Hey all, I am having a lot of trouble getting CUPS to work on my Raspberry Pi Zero W running Raspbian OS bullseye (32 bit), here are the steps that I took.
(Guide that I am using for reference.)
- I used Raspberry Pi Imager to flash the SD Card, enabled SSH, and connect to Wifi.
- Once SSHed into the Pi, I ran:sudo apt updatesudo apt upgradewhich upgraded libfuse2
- Then I ransudo apt install cupsonly to find out that CUPS 2.3.3op2 is already included in the newest version of Raspbian
- Afterwards I reboot the Pi and ransystemctl status cupsto make sure that CUPS runs at boot
- Once rebooted I ransudo usermod -a -G lpadmin pito add the 'pi' user to lpadmin and confirmed that it was added by runningcat /etc/group | grep lpadminand gettinglpadmin
117:root,piin return. - Next I ransudo apt-get install foomatic-dbto install all of the needed printer drivers. Runningapt list –installed | grep foomatic-dbfailed and return this errorE: input:0-12: error: Expected pattern–installed^^^^^^^^^^^^
- After I restarted CUPS withsudo systemctl restart cupsand went onto the WebGUI
- On the WebGUI, I logged into the admin page and selected my Samsung printer. Once I clicked 'continue' on this page, I got the error message:unable to get list of printer drivers:success
117:root,piin return.For troubleshooting, I have tried the following:
- I ran/usr/lib/cups/driver/foomatic listwhich returned a long list of printer drivers / PPD files which included:foomatic:Samsung-SCX-4x25-lj5gray.ppd" en "Samsung" "Samsung SCX-4x25 Foomatic/lj5gray" "MFG:Samsung;MDL:SCX-4x25 Series;CMD:PCL5E,PCL6,FWV,EXT;DRV:Dlj5gray,R0,M0,TG;""foomatic:Samsung-SCX-4x25-pxlmono.ppd" en "Samsung" "Samsung SCX-4x25 Foomatic/pxlmono" "MFG:Samsung;MDL:SCX-4x25 Series;CMD:PCL5E,PCL6,FWV,EXT;DRV:Dpxlmono,R0,M0,TG;"So, the driver for my printer is there and on the Pi.
- I tried the whole thing again on a different Raspberry Pi Zero W, got the same error. And with a different printer.
- Ransudo tail -f /var/log/cups/error_logto see error messages, which returned

Has anybody encountered this? Any fixes? Am I missing something?
