Bug 1694797

I now think that this is a cups issue, because printing a test page via the web interface at: http://localhost:631/printers/HP-ColorLaserJet-MFP-M278-M281 results in the same error message on the printer display.

I do not understand why assignee was not moved...

Hi Jan!

thank you for reporting the issue! Would you mind providing files with outputs of:

1) $ lpstat -t
2) $ sudo lpinfo -l -v
3) $ cat /etc/cups/ppd/<your_print_queue_name>.ppd
4) turn on debug2 log level in cupsd, restart CUPS, try to print a test page and attach journal logs for the job or time frame when you issued a job.

Generally, the things which are described in https://fedoraproject.org/wiki/How_to_debug_printing_problems .

Hi Zdenek,

After installing the plugin by running
hp-plugin -i
as suggested in bug 1694663, I can print the test page.

Are you still interested in the requested information?

Would it somehow be possible to indicate that the plugin is missing in the GUI? I did not think of this possibility, because I specifically selected this printer because I thought that it did not require a proprietary plugin, as indicated on https://developers.hp.com/hp-linux-imaging-and-printing/supported_devices/index.

Yes, it should print test page at least ;) - IMO plugin is needed only for scanning (until we will prove different thing :) ), printing should work, especially as it seems it is IPP everywhere enabled printer - but there could be an error in IPP server in printer, so that's problem sometimes. And can you create a print queue in gnome-control-center when you issue an IP address? Then g-c-c should find your printer too.

Ad investigating the issue:
You can check files which does to CUPS and out:
1) to CUPS:
- in /var/spool/cups should be a file starting by letter 'd' - it is file from app (g-c-c) to CUPS - please check if it is test file and attach it too
2) out of CUPS:
- it is already filtered job - you can get it by creating new filedevice printer (set FileDevice to Yes in /etc/cups/cups-files.conf and restart cups) with lpadmin, but with ppd of your printer:

$ sudo lpadmin -p test-printer -v file:/tmp/ps -P /etc/cups/ppd/<ppd_file_of_affected_printer>.ppd -E

- then try to print test page to it - there will be 'ps' file in /tmp dir after 'printing' is finished - please attach it too.

Do you mean in gnome-control-center? Unfortunately, I do not think so - it would need to depend on a database, but as you can see, there is no reliable one...

Start:
All via g-c-c:
1. Remove all printers
2. Wait until printer appears again via DNS-SD
3. Add... printer
	Add...
	Select discovered printer
	Add
4. Wait until the added printer appears in the Printers pane.
5. For the added printer, go to Printing Options, click the Test Page button.
   This happens
	* On the LCD display of the printer the following appears: "Unable to print file. File is corrupt."
	* The ink levels of the printer appear for the printer in the Printers pane.
6. Note: once this ink level has been established, it stays visible, even after closing and starting g-c-c.

Removed all files in /var/spool/cups
   (files starting with c, d, and a tmp directory)


made lpstat.txt
made lpinfo.txt

made *.ppd files strange enough there are two of them.
[jan@nyx ppd]$ ls -sla /etc/cups/ppd/
total 32
 4 drwxr-xr-x. 2 root lp  4096  3 apr 11:41 .

12 -rw-r-----. 1 root lp 11587  3 apr 11:41 HP-ColorLaserJet-MFP-M278-M281.ppd.O
The only difference is the paper size, I cannot remember that I changed this manually. I am using A4 paper.

Enabled cups debug level 2
Tried to print a test page. See cups_journal.txt for the log messages

Interestingly printing to the printer works, except for the test page from g-c-c.

Yes, that is what I meant.


Separate remark:
Note that messages about a wrong paper size go to the LCD screen on the printer. I can accept there to continue with the loaded format. I do not get this feedback on my Fedora system.

Hmm... output of filters is corrupted - these filters are part of cups-filters, reassigning component.

Reported upstream https://github.com/OpenPrinting/cups-filters/issues/104 .

Jan, I found out the crash is fixed in newer cups-filters (printing does not crash, but one line is cropped - I do not find it critical though), would you mind testing https://koji.fedoraproject.org/koji/taskinfo?taskID=34046177 if it works for you too?

Zdenek, I confirm that I can print a test page with the new build. Thanks for your great work!
