Mai 15 20:36:20 phantom-pc cupsd[1805]: [Job 55] Backend ipp returned status 5 (cancel job)

I marked the relevant log line. Printing itself works beautifully on my LP2844, but when using the native Chrome dialog it fails probably because they send something unintelligible regarding color. Would it make sense to ignore this?

Second problem: I cannot use ipps on my machine (Nobara 39, which essentially is a latest greatest Fedora) because I get an error that the CUPS pki is invalid. When I modify the local connection address to just ipp it works. Is this expected?

EDIT: Firefox does not have the issue but they also list an explicit color setting which is set to black and white and can't be changed.

michaelrsweet commented 1 month ago

WRT "ignoring" unknown values, Print-Job and Create-Job will do so (assuming "ipp-attribute-fidelity" is false) but Validate-Job explicitly has to report unknown/unsupported/conflicting values or attributes (that's its purpose...)

Can you enable debug logging for LPrint (open web interface and toggle the log level in the View Log File page) and CUPS (cupsctl --debug-logging) and attach the logs to this issue? That will help me determine where the problem lies.

WRT the PKI errors, again having debug logs would be useful.

I am not seeing the log option for lprint in the web interface weirdly enough unless I'm blind. any more specific hints? Cups I was able to enable debug logging, see below.

The funny thing is lprint logs taht the connection is now encrypted, still cups seems to get a PKI error back (see screenshot)

modded the systemd service file but the output is not really any more plentyful. lprint does not complain in the logs but it does apparently to CUPS

Ok so lprint is ot printing any debug info for this print trial, I again confirmed on the console it is in fact printing debug info on startup (see the 'D' markers), but when I try to launch the job the causes the CUPS error only cups complains, lprint just prints infos and seems happy. weird.

As for the Chrome issue, I switched back the printer to ipp protocol so that the connection works, and I have attached the resulting logfile.

Here there is a lot more lprint debug output in there. This issue exists with both printers (the Zebra LP2844 and the DYMO, Dymo example in the log).
