Debian Jessie, Xfce4 ver. 4.10, HPLIP ver. 3.14.6 **UPDATE:** This issue is still present as of Debian Buster... After upgrading from Debian Wheezy to Jessie (yeah, I know...), started getting the following (level 1/alert) notice in the boot logs: hp-systray[PID]: error: option -s not recognized Closer scrutiny of the subject log entry revealed that the command /usr/bin/python /usr/bin/hp-systray -session .... had been attempted at some point during the login process. Running said command in a terminal does indeed produce the subject error squawk. Turns out that -session is not a valid switch for this command... Never saw said notice when running Wheezy. Internet research yielded the observation that this problem seems to be relatively rare, seemingly innocuous, has been around for at least 10 years, and has never been explained. I have noticed that, if I kill the hp-systray process before shutdown, the problem is not there upon the subsequent boot, but will return for any follow-on boot not preceded by said "kill" operation. Any ideas?

I'm running Chaos Calmer 15.05 (openwrt firmware) in a TPLINK WDR3600 and I'm trying to install SANE + HPLIP in order to get scanner over lan network. I installed sane-libs and sane-daemon + dependencies from official distribuition feed (for Chaos Calmer) and because HPLIP is not available for Chaos Calmer, I had to install HPLIP for 14.07 in third distribuition url , I don't know if the error below is because of this "version", but.... Well... Using sane-find-scanner I get scanner found out by the system, and scanimage -L returns me: > device > `hpaio:/usb/HP_LaserJet_Professional_M1132_MFP?serial=000000000SS17TR2PR1a' > is a Hewlett-Packard HP_LaserJet_Professional_M1132_MFP all-in-one Although scanimage -T returns: > scanimage: open of device > hpaio:/usb/HP_LaserJet_Professional_M1132_MFP?serial=000000000SS17TR2PR1a > failed: Error during device I/O Can someone help me?

I was investigating further an issue already reported here . The problem is: after having upgraded the **hplip** driver to **3.16.2**, the scanner in my all-in-one printer **HP Color LaserJet Pro MFP M277dw** does not work any longer (while the printer does). Today I found other oddities that seem specific to **hplip** rather than to **sane**, whereby this other post. I use **Ubuntu Linux 14.04 LTS**. In all that follows the device is connected and powered-on. The hplip page for that device is here . # Evidences # **a.** Moving on from the **sane** community page on Ubuntu , I followed the suggestion to run sudo hp-setup. The answer is warning: CUPSEXT could not be loaded. Please check HPLIP installation. **b.** If run hp-doctor, the welcome message is error: This distro (i.e ubuntu 14.04) is either deprecated or not yet supported. This sounds utterly odd to me, because the previous hplip did not dare to complain this far of the very same distro. The complete output of hp-doctor is available from here on Paste Ubuntu . **c.** Ever more puzzling, if I open the HP device manager, I am presented with the window which seems a false statement to me, since the device works as a printer at the very least. If I click on Setup device... I get again the same dialogue window. And **CUPS** on localhost:631 indeed confirms that the printer is there ready to be found, nice and idle. # Questions # Is there a way to have the commands hp-setup and hp-doctor run smoothly so that I can fix the scanner issue down the line? If not, how do I downgrade the hplip driver to the previous stable version? Installing 3.16.2 has led to more havoc than joy.

Using my BananaPi as a printer server (Armbian Debian 10 (buster)) Ran the following commands: - aptitude install cups - aptitude install printer-driver-escpr - aptitude install hplip - aptitude install hpcups Printers were added to the CUPS server through the webgui. The Epson printer works, but sending jobs to the HP printer causes the following error:

"Filter failed"

(I did have this working on my raspberry pi at one point, but after an apt-get update/upgrade it started getting the filter error, so I erased the OS and started new on a new device) All the solutions I could find for this problem seem to indicate I need new drivers. I found two driver sources for this printer (hp m1319f): - https://developers.hp.com/hp-linux-imaging-and-printing/gethplip (Latest: 3.20.6) - https://www.openprinting.org/driver/foo2zjs-z1 The driver installed by aptitude was 3.18.12. From what I can tell there are no older/newer versions I can choose from in the package manager. I tried manually downloading the latest hplip and executing the .run file but that results in this: Traceback (most recent call last): File "/usr/lib/python2.7/site.py", line 70, in import traceback ValueError: bad marshal data (unknown type code) Traceback (most recent call last): File "/usr/lib/python2.7/site.py", line 70, in import traceback ValueError: bad marshal data (unknown type code) ./hplip-install: line 20: [: : integer expression expected Traceback (most recent call last): File "/usr/lib/python2.7/site.py", line 70, in import traceback ValueError: bad marshal data (unknown type code) If I manually execute ./configure I get the following output: ... checking for python3 version... 3.7 checking for python3 platform... linux checking for python3 script directory... ${prefix}/lib/python3.7/site-packages checking for python3 extension module directory... ${exec_prefix}/lib/python3.7/site-packages checking for path to Python.h...

One oddity I noticed is that driver says my printer is color: (HP LaserJet m1319f MFP, hpcups 3.18.12, requires proprietary plugin (color, 2-sided printing)) I am stumped. I saw this solution for bad marshal data, but I don't it will work in my case: https://stackoverflow.com/questions/30861493/how-to-fix-python-valueerrorbad-marshal-data

This thread is derived from an askubuntu-thread There the thread-opener tried to install hplip-libraries, but failed because hplip handled his system as a pure Debian one, instead of an Ubuntu one. A very related problem affects users of distros other than Ubuntu -- because Ask Ubuntu is for Ubuntu only, I am opening this thread here to hopefully help some people of other distros. The symptom of the problem is: during the execution of hplip-*.run, you are asked for your root password, but, entering your correct password, the installer will tell you your password is wrong. This only affects people with a disabled root account (people using sudo). How can one fix this problem and install the hplip on a machine that has the superuser disabled?

I posted this to raspberrypi.stackexchange yesterday with no responses and only 4 views, so I'm reposting and expanding the original post here to reach a wider/different audience. I have an old Pi-3 running Stretch. I have what apt-get install tells me is the latest version of everything installed. I plug in an old HP PSC 750xi All-In-One USB printer/scanner. The Pi recognizes the printer features of the device, and I can successfully configure CUPS to use the printer. But I cannot get the Pi to recognize the device's scanner. I have a separate laptop running Ubuntu 20. When I plug the USB device into that laptop, I can use hplip's hp-scan tool to successfully scan. But none of the Pi's hplip or sane tools (hp-setup, hp-probe, hp-check, hp-scan, scanimage, sane-find-scanner ...) recognize the USB scanner. Clearly, as the Ubuntu test proves, hplip **does** support scanning for this all-in-one printer/scanner. And hplip documentation indicates that the device is supported both for the Pi hplip version (3.16.11) and for the Ubuntu version (3.20). I also have an HP 6978 Network printer/scanner that the Ubuntu system sees on the network and can manipulate with the hplip tools. The Pi's CUPS server sees and can use that network printer. But, like the USB device, the Pi fails to 'see' the network scanner. My understanding is that these scanners are supported through use of the libsane-hpaio backend. Yes, I have installed the libsane-hpaio package on the Pi. I've run scanimage on the Pi with SANE_DEBUG_DLL=128 and SANE_DEBUG_HPAIO=128 but the output simply reports no scanners found without indicating any errors of any kind. On the Ubuntu system, the same debug output shows successful discovery of both the network scanner and the USB-connected scanner. But there appear to be more fundamental issues. The full lsusb output is now reporting:

It's that very first line I'm concerned about. I'm thinking this is a possible Python version issue as python -V reports Python 2.7.13. But Python3.5 is installed too (though I have no idea which package might have installed it,) and python3 -V reports Python 3.5.3. So, I'm thinking half the packages are using python v2 and half are using v3 and I don't know which is using which. Nor do I know how to configure them to use a different version. Plus, I'm a bit hesitant to even try to reconfigure/upgrade the base python from v2 to v3 for fear of breaking the entire system. And I'm concerned that the libusb and usbutil packages are so old, while hplip and its companions are much newer ... some kind of a mismatch somewhere, but I hardly know where to start. I hate to rebuild the Pi from scratch because I don't want to have to rebuild its LAMP stack, web server, nextcloud server, etc. but that may be my only option. I cannot find any missing packages or dependencies on the Pi. I have tried removing and re-installing hplip and a number of other packages. Clearly, there is some configuration difference between the Pi and the Ubuntu platforms. But after several days of struggle, I'm stumped. Anyone have any ideas?

My OS is Debian 11 and my printer is an HP LaserJet Pro MFP M28a. After the first install using the hplip package, both printing and scanning were working fine but, for some reason, I had to reinstall the printer and then the scanner became unreachable from XSane at all. I have tried several options and I either get error message code 9 ("error: SANE: Error during device I/O") or 10 ("error: SANE: Out of memory (code=10)") when trying to launch XSane. Is it actually an error from XSane or from the whole configuration on my computer? By the way, here is the output from hp-check:

I know there is some warning telling me Debian 11 is *not supported* and that some required packages are *missing* (and I did not remove them since then), but I **did manage** to make the scanner work at first, so there must be a way to get it back running (without messing too much with the packages).

I have (LMDE2) debian 8 (jessie) and want to install network printer. My printer is supported in hplip v3.18.5 but only v3.14.6 is available, therefore I need to compile hplip from source. There is list of Dependency Packages which I am looking for.

I have a HP LaserJet CP1025NW (color) printer installed on a Linux Mint 20.1 machine using HPLIP (required plugin installed, version 3.20.11). For some reason, whenever I try to print a document (e.g. PDF, a text file, etc.) with black text inside, the text is *always* printed using the three CMY colors. The result is not as pretty looking as if the text had been printed using the black cartridge only; also, it is a waste of ink. Notice that if the *same* document is printed via a Windows machine on the *same* printer, I get the expected result of black text printed in pure black. I could not find any option (neither in CUPS, nor in HPLIP) to adjust this undesired behavior. Any help is appreciated.

I have a plug computer that I want to use as scanner server using sane. It already worked with a different plug, so I know for sure that the scanner and sane are workable together. If I issue scanimage -L as root I get this output: device `hpaio:/usb/Deskjet_F300_series?serial=CN73CGJ05504KH' is a Hewlett-Packard Deskjet_F300_series all-in-one which is what I am expecting, but when I call the command as saned I get this output: No scanners were identified. [...] If I call sane-find-scanner as saned it brings up: found USB scanner (vendor=0x03f0, product=0x5511) at libusb:001:015 Now the interesting part is that the vendor and product is not detected here, but when I do the same as root this is the result: found USB scanner (vendor=0x03f0 [HP], product=0x5511 [Deskjet F300 series]) at libusb:001:015 So, somehow the root user has access to the list of vendors (and thus is able to detect the scanner) while saned is not. I don't want to run the saned server as root so I need to figure this out. All settings I did in saned.conf are for the network interaction, but my problem is on the local host, so I skip the config file (but of course can provide it if necessary) saned groups: saned scanner I assume that I need to change the privileges of the file where vendor and product are mapped (/etc/sane.d/hp.conf), but that is already readable by sane. -rw-r--r-- 1 saned scanner 396 Dec 12 2010 hp3900.conf -rw-r--r-- 1 saned scanner 76 Dec 12 2010 hp4200.conf -rw-r--r-- 1 saned scanner 238 Dec 12 2010 hp5400.conf -rw-r--r-- 1 saned scanner 497 Dec 12 2010 hp.conf -rw-r--r-- 1 saned scanner 22 Dec 12 2010 hpsj5s.conf Same for /etc/sane.d/dll.d/ -rw-r--r-- 1 saned scanner 38 Dec 10 2013 hplip Interesting is that neither of these files contain the Deskjet_F300_series information, so maybe there is another file? Also, while the scanner does have a printing option, I'm not interested in this. I did read [this post](https://unix.stackexchange.com/q/184367/54677) , but I would prefer not to do what is described there, because somewhere the information is already present and I would like to access that place, from the saned user.

I have installed Void linux which is otherwise working very well. It certainly is a smooth and stable distribution with a great package manager (xbps) which does dependency resolution also. The packages in repository (e.g. LibreOffice) are fairly recent. However, I have not been able to make my Void Linux installation work with my HP Laserjet M1136 MFP printer/scanner. I have installed hplip and cups. I have tried to install it using command sudo hp-setup -i and also using localhost:631 on browser. The printer is recognized but on there is always 'Filter failed' error on trying to print. This printer/scanner works well with a Debian Stable Linux installation on a separate partition of same desktop computer. I found that there is a package called hplip-data installed on Debian but this package is not present in Void Linux repository. What could be the problem and how can it be solved? Thanks for your help. Edit: /etc/printers.conf file is shown below: NextPrinterId 12 PrinterId 11 UUID urn:uuid:64208fbb-c084-36f7-6ffd-55aa73ae7885 Info HP LaserJet Professional M1136 MFP Location rnhome MakeModel HP LaserJet Professional m1136 MFP hpijs, 3.20.9 DeviceURI hp:/usb/HP_LaserJet_Professional_M1136_MFP?serial=000000000QHBV1CYPR1a State Idle StateTime 1617539017 ConfigTime 1617539027 Type 8425484 Accepting Yes Shared No JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer Edit: Printer started working after I used hp-plugin -i command.

I am trying to run HP's printer software which was upgraded recently and broke all my printing. I run a constantly upgraded Arch (which is 5.10.14 as of Feb 28, 2021). Apparently they use Qt now so it is some kind of requirement so I spent 2 hours building all this Qt stuff. It seems crazy that HP is requiring linux users to spend hours building obscure packages just so they can print. lpstat -a says the printers are ready and working/idle, but nothing can print to them. The cups log says the print failed to a "backend error". Anyway, hp-setup now just hangs on startup and hp-check gives an error that PyQt4 cannot import QtCore, which is the standard way PyQt users try to verify the version of Qt they are running under. So, apparently there is some kind of version conflict between the two. Here is the relevant section of my pip list:

PyOpenGL              3.1.5
pyOpenSSL             20.0.1
pyparsing             2.4.7
PyQt3D                5.15.2
PyQt4-sip             4.19.24
PyQt5                 5.15.2
PyQt5-sip             12.8.1
PyQtChart             5.15.2
PyQtDataVisualization 5.15.2
PyQtPurchasing        5.15.2
PyQtWebEngine         5.15.2

So, is the problem that I have PyQt5 on my system and the HP software wants PyQt4? If so, can I have both on the same system? What is the procedure to diagnose this?

Problem Description - Unable to print Device name : HP LaserJet M1005 MFP USB printer OS : Linux 3.8.13-1-MANJARO #1 SMP PREEMPT x86_64 GNU/Linux Error Description : 1. Cups is working well and fine. 2. I am able to access localhost:631 3. Hplip is installed 4. Tried to print a PDF file. 5. After issuing print command, the print queue shows the error "Processing - Not connected?" 6. Further exploration for the print job error led me to an error "Filter failed" What I have tried so far : - Removed and added the printer through the cups web interface - Tried installing the printer using hp-setup under root. I am not sure what to do at this point. Could someone please tell me what to do or atleast where to look next to have a chance at solving my problem...

In order to install HPLIP 3.20.6 I need to install the dependency python3-pyqt4. > error: A required dependency 'python3-pyqt4 (PyQt 4- Qt interface for Python (for Qt version 4.x))' is still missing. > error: Installation cannot continue without this dependency. > error: Please manually install this dependency and re-run this installer. When trying to install through apt I get the error that it cannot be found. > E: Unable to locate package python3-pyqt4 How can I install this dependency? I need to install HPLIP 3.20.5 or greater in order to be able to use a new printer so any help in resolving this is much appreciated. Thank you. Edit: To further clarify. The printer I am trying to connect to is HP Envy 6020. On the HPLIP list of supported devices the Envy 6000 series is supported but it requires a minimum of 3.20.5 HPLIP to run. Ergo, I need to install that version and it is requiring python3-pyqt4 in order to install.

I am dual booting my Windows 10 laptop and I chose the Linux Mint 19.3 distro to run alongside windows with the dual boot option. When I boot into Linux I'm not having any success connecting to my USB printer which is a LaserJet M1212nf MFP and that printer is supported by HP. I've got hplip 3.17.10 and hplip-gui 3.17.10 installed and I also ran hp-plugin to install the plugin. When I run hp-setup from the command line I select USB on page one and then when I click on Next I get a "No devices found" message. Just for good measure I plugged in my usb printer before running hp-setup. Update: I've tried running hplip.3.20.5.run and I'm getting this message: Following dependencies are not installed. HPLIP will not work if all REQUIRED dependencies are not installed and some of the HPLIP features will not work if OPTIONAL dependencies are not installed.

I'm using this command to print multiple files with lp in linux but each document is being finished with stapler: lp -d printername -o "HPPaperSource=Tray3" -o "HPStaplerOptions=1StapleRightAngled" /file/1.pdf /file/2.pdf Printer driver is HPLIP. What i want to achieve is to finish both documents with one staple and not each document with one staple.

* OS: Arch Linux * uname -r: 5.5.4-arch1-1 * pacman -Q hplip: hplip 1:3.19.12-1 I usually leave the setting for printing double-sided on "Long Edge" or whatever exactly it is called in English. Printing a document which has only 1 page makes the printer print the document in double-sided mode, which is expected behavior. So the printer then prints one page of the document, turns the sheet, does not print anything on the empty page and then ejects it. Is it possible to have the printer/driver automatically recognize that the document is only 1 page long and can get printed in single-sided mode, i.e. without the sheet turn?

Santa brought me a new printer - an HP Envy 5010 but I can't get it working. The paper documentation supplied with the printer was useless (omitted to mention that you need to / how to open the case and install ink cartridges) and the only setup information was to "download the app for iphone or android". Running this app on my tablet, it discovered the device without any problem. hp-setup cannot find the printer - I've tried the 3 auto-discovery methods in hplip (SLP, bonjour/mdns, avahi) even if I tell it the printer's IP address (as reported in lcd screen on the printer). I have tried each of 1-4 as options for "jetdirect port". There is no firewall between my Linux host and the printer. From the command line, I can connect to ports 631 and 9100 using telnet, and to the http and https admin consoles. But I can't connect to 161 and 162 which are described in the troubleshooting at https://developers.hp.com/hp-linux-imaging-and-printing/KnowledgeBase/Troubleshooting/TroubleshootNetwork Cups has discovered the printer (twice!): Discovered Network Printers: HP ENVY 5000 series [0531AC] (HP HP ENVY 5000 series) ENVY 5000 All-in-One Printer series (HP ENVY 5000 series) Meanwhile, HP says they don't provide *any* drivers for it at https://support.hp.com/us-en/drivers/selfservice/model/14095645 (but that is auto-detecting my Linux OS, shame HPLIP wasn't so good) Unfortunately none of the drivers listed for other OS seem to have a seperate PPD file and my CUPS installation doesn't have one for an Envy 5010. The one for a HP Envy 5530 seems to be working with the test page). Has anyone successfully configured an HP Envy 5010 to scan? How? Should I expect to have to reconfigure CUPS if the IP address changes?

I can get it working over USB, but we really want this on the network. The printer is an HP LaserJet Pro MFP m26nw, the OS is Mint 19.1 64 bit Mate. After installing, the test page job changes to a "stopped" status and an error pops up that says, "there was a problem processing document 'test page'".

I've tried with Jetdirect and IPP and the hp protocol. I'm using an exact match driver from Hplip / foomatic when prompted for one (although one of the methods didn't ask for a driver). All produce the same results. What can I try?

I installed HPLIP on my raspberry pi to use CUPS as per [here](https://unix.stackexchange.com/questions/511669/cups-selecting-a-driver-for-a-hp-printer/511673#511673) but some packages are simply not installing. I have tried:

apt-get -f install hplip

,

apt-get install qt4-default qt4-designer qt4-doc qt4-dev-tools python-qt4

and the same for PYQT5,

apt-get install qt5-default

and countless other things. Does anyone know what to do. My latest string (after doing all of the above and more for nearly 2 hours) is this: **couldn't get the code snippet mode to work - don't know why.** MISSING DEPENDENCIES -------------------- Following dependencies are not installed.
