Setting up a printer in KDE and Leap 16 Alpha

rbeef · April 23, 2025, 11:56am

In Leap 15.6, the printer was easily set up from YaST2, by providing its IP (it’s a network printer, and it worked without an issue. Now, on 16-Alpha, YaST2 Control Center is gone and although Printers section from KDE’s System Setting correctly detects and lists my printer, I can’t use it, no matter if I connect trough socket, http, ipp: trying to Print a Test Page gives me Failed to perform request: No such file or directory error. And before that, when adding it, CUPS requires root password, something I don’t recall happening on Leap 15.6 (although I might be wrong about that one). Is there a way to have my printer working in current Leap 16 Alpha?

Tell us the printer modell.

rbeef · April 23, 2025, 12:10pm

Right, sorry, forgot to mention printer’s name: it’s Ricoh MP C3003, using Ricoh MP C3003 - CUPS+Gutenprint v5.3.4 drivers (as suggested by the KDE’s Printers dialogue).

Can you configure the printer successfully by accessing the CUPS web interface via a browser?
http://localhost:631

This printer model should support the IPP Everywhere printing protocol, although it might need enabling via the printer’s front panel interface first. CUPS should then discover the printer (via DNS-SD) without any CUPS configuration required.

Is it discovered via the following commands?
ippfind
avahi-browse -t _printer._tcp
You may need to install ‘avahi-utils’ first for the last command.

rbeef · April 24, 2025, 7:05am

The printer is visible at http://localhost:631/printers, as it is visible on Printers section from KDE System Settings. Trying to print a test page from the above mentioned link gives me the same Unable to print test page: No such file or directory, as I get when trying the same thing from KDE Printers window.

Trying to print anything from Libre Office gives me an error (Could not start printer. Please check your printer configuration)

ippfind or ippfind -ls outputs nothing.

lpinfo -v finds my printer as network socket://192.168.1.96 (among other printers in the network), however specifying that address on KDE Printers dialogue makes no difference, it still won’t print.

deano_ferrari · April 24, 2025, 7:11am

That’s only reporting what you have configured already?

What does a port scan return?
nmap -F 192.168.1.96

deano_ferrari · April 24, 2025, 7:14am

Are you the administrator for the printer? Is IPP printing enabled on it?

I’m not sure about IPP, but it worked without a problem a week ago, when I was using Leap 15.6 and YaST2 to configure it.

deano_ferrari · April 24, 2025, 7:20am

Yes, but you were using a gutenprint driver right? Did you keep the printer ppd config from the /etc/cups/ppd/ directory?

rbeef · April 24, 2025, 7:22am

Nope, because I freshly installed Leap 16.0 and formatted the former Leap 15.6 instalaltion.

deano_ferrari · April 24, 2025, 7:25am

Ok, let’s stay with your existing Leap 16 config. Show the results from
sudo egrep -i "name|model|filter" /etc/cups/ppd/*

That all checks out fine. Try to print a simple text file or PDF file you have at hand eg
lpr -P MP_C3003 /path/to/file.txt
Does that succeed?

rbeef · April 24, 2025, 7:40am

I created a TXT for testing, and I got this:

lpr -P MP_C3003 file-to-print.txt 
lpr: Unsupported document-format "text/plain".

Then I exported the TXT file as PDF and tried again:

lpr -P MP_C3003 file-to-print.pdf
lpr: Unsupported document-format "application/pdf".

deano_ferrari · April 24, 2025, 7:44am

Hmmm…are you missing the ‘cups-filters’ package?

rbeef · April 24, 2025, 7:53am

Possibly, since I get this:

Refreshing service 'openSUSE'.
Loading repository data...
Reading installed packages...
Package 'cups-filters' not found.
Resolving package dependencies...
Nothing to do.

Shouldn’t this be installed by default or at least be available in the official repos?
