How to check if printer is out of paper

How can I check if cups printer is out of paper using commands only (no gui). EDIT: Is it possible to check that using python? EDIT2: I tried it with different printer (EPSON TM-m30). When I try to print without paper it stuck in Processing. printer-state = processing
printer-state-message = Rendering completed
printer-state-reasons = none But I still cant get info about paper. I am not sure if it can help you, I created json file from some python code which reads printer attribues: https://pastebin.com/u97U9TnQ # Update We bought another printer (Star Micronics TUP542), the printer has out of paper sensor: Near End Paper Sensor , but I can't find any manual how to work with this sensor (sensor is plugged into printer). Does cups have some command for it? Or do I need to use some different tool? I tried to get attributes using python, here is the result (json): https://pastebin.com/Z3Tiz5g9 BTW, *printer-state* is always 3, with or without paper. Is it supposed to change when printer is out of paper? I think *printer-state-reasons* should say something about missing paper, but there is always ['none'] # Update 2 Maybe I should try ESC/POS commands (here ). I found some codes on page 157 *Transmission of status*. > n = 1, 49: Sends paper detector status But I am not sure what does mean n = 1, 49 Is it string or decimal or hex values? Why there is comma between 1 and 49. I tried this python code:

command = [0x1D, 0x72, 1]
dest="/dev/usb/lp1"

with open(dest,"wb") as file:
	file.write(bytearray(command))

with open(dest,"rb") as file:
    data = file.read() # hangs
    print(data)

But read function hangs and never returns. PS: I also tried different values ([0x1D, 0x72, 49], [0x1D, 0x72, 1, 49], [0x1D, 0x72, 1, 0x49]), but without success. By the way, when I use sudo cat /dev/usb/lp1 it prints lot of ###. When I use hexdump after cat I see this repeating sequence: 23 06 00 00 00 00 00 00 00
