How can I make my printer actually print, not just accept print jobs and delete them from queue?

I installed a mint Raspberry Pi 4 with Raspbian and wanted to connect my Brother HL-2240D printer to it. I used the Driver Installation tool provided on https://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&lang=en&prod=hl2240d_all&os=128 and followed the steps to install the lpr and cupswrapper. The whole transaction looks like this: sudo bash linux-brprinter-installer-2.2.2-2 Input model name ->HL2240D You are going to install following packages. hl2240dlpr-2.1.1-1.i386.deb cupswrapperHL2240D-2.0.4-2.i386.deb OK?

Afterwards the printer showed up in the Raspbian printer config and in CUPS, so I tried to hit the **Test Print** button as well as sending a simple text file through

-d HL2240D /usr/share/cups/data/testprint

. All of this works, the queue counts up my attempts and is cleared after some seconds, but the printer does not spit out any page.

-p

shows my printer is idle and if I am unplugging the USB and send another print request, it shows

for the printer to become available

, plugging it in, it becomes available, but doesn't print. What am I doing wrong and what else could I check?
