Created attachment 1613675 [details] cups whole log Description of problem: Adding the printer via printer-gui (in settings) added an entry in the menu, but no printing options or details within it. Neither printing (test page) nor scanning was possible. I used HP Device Manager (HPLIP) instead. The 'setup' process correctly detects the device (and even the fax). 'Add printer' results in an error message: Printer queue setup failed. Error : successful-ok-ignored-or-substituted-attributes However, the fax is added. Find the full log attached. The printer works properly on another laptop of mine. Same setup (Fedora 30, Gnome), same versions of related components (as far as I know). I tried copying the PDD file from the laptop with the working setup following [this](https://forum.manjaro.org/t/printing-not-working-and-cant-install-new-printer-either-after-yesterdays-update/101721/18) answer, but no success. It may be worth mentioning that sudo systemctl stop org.cups.cupsd.service was denied with the hint that the service wasn't running and sudo systemctl start org.cups.cupsd.service was denied, too: Failed to start org.cups.cupsd.service: Unit org.cups.cupsd.service not found.

Hi, thank you for reporting the issue! First, it seems you broke your cups daemon with your manual change from link you shared, deducting this from log entry: "Sep 10 19:26:05 ruediger cupsd[28448]: Unable to finalize "/etc/cups/printers.conf": Permission denied" 1) Please stop cups daemon (it is called just "cups.service" in Fedora, that answers why you found out org.cups... does not work) $ sudo systemctl stop cups 2) remove any /etc/cups/printers.conf* - this will remove all your installed print queues 3) start cups again $ sudo systemctl start cups I have several questions, please look into them further down: (In reply to lurxen from comment #0) > Created attachment 1613675 [details] > cups whole log > > Description of problem: > Adding the printer via printer-gui (in settings) Would you mind telling me what do you mean by this?

Do you mean print queue was created, but printing did not work? Can you try to catch logs for GNOME created queue when you try to print?

I have essentially the same issue. Except, everything was working on Fedora 30. A recent package upgrade that included the following (not NOT hplip): Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: wavpack x86_64 5.1.0-16.fc30 updates 180 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: libevent x86_64 2.1.8-7.fc30 updates 231 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: kmod-libs x86_64 26-3.fc30 updates 58 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: kmod x86_64 26-3.fc30 updates 115 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: cups-libs x86_64 1:2.2.12-1.fc30 updates 252 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: cups-ipptool x86_64 1:2.2.12-1.fc30 updates 5.7 M Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: cups-filesystem noarch 1:2.2.12-1.fc30 updates 12 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: cups-client x86_64 1:2.2.12-1.fc30 updates 64 k Sep 03 23:30:05 pyewachet.ga.holmgrown.com dnf-automatic[18533]: cups x86_64 1:2.2.12-1.fc30 updates 1.4 M After that, printing a PDF to the printer resulted in RAW PDF, not formatted pages being printed.

Hi Howard, thank you for letting me know! It is helpful, but I still need to locate the issue more precisely. Would you mind installing the print queue under cups-2.2.11, then upgrade cups, enable its debug logging, try to print and attach the debug log for the job (described at https://fedoraproject.org/wiki/How_to_debug_printing_problems). Plus please attach the ppd for the queue, if it exists.
Hi Zdened! Thanks for the super fast, friendly and competent reply – and sorry for my delay answering it. We are working on the infrastructure for open source hardware and there's quite a lot going on lately. I just executed your suggested commands. See my answers below ↓ (In reply to Zdenek Dohnal from comment #1) > Hi, > > thank you for reporting the issue! again: thank you for your efforts here :) > > First, it seems you broke your cups daemon with your manual change from link > you shared, deducting this from log entry: > > "Sep 10 19:26:05 ruediger cupsd[28448]: Unable to finalize > "/etc/cups/printers.conf": Permission denied" > > 1) Please stop cups daemon (it is called just "cups.service" in Fedora, that > answers why you found out org.cups... does not work) > > $ sudo systemctl stop cups > > 2) remove any /etc/cups/printers.conf* - this will remove all your installed > print queues > > 3) start cups again > > $ sudo systemctl start cups Done.

When I click on 'details' or 'printing options' in GNOME Control Center, I won't see any details or printing options. Printing queue is always empty, too. > > > I used HP Device Manager (HPLIP) instead. The > > 'setup' process correctly detects the device (and even the fax).

Did it. During the setup (as a network printer) I unchecked the box for setting up the integrated fax and marked the checkbox for printing a test page after the setup. By the way, setting up the fax always works.

Hi, it is actually upstream issue https://github.com/apple/cups/issues/5639 . The setting PPD fails because ppd contains 'Custom' option, which is now denied. I can reproduce it by 'lpadmin' command: lpadmin -p test -v socket://IP:9100 -m drv:///hp/hpcups.drv/hp-officejet_pro_7740_series.ppd -E lpadmin: Unable to open PPD "/tmp/046c85d818b45": Illegal option keyword string on line 303.
Cool, thanks for checking this out! Do you know of any workaround, how I can do the printer setup with the 'regular' option in order to avoid this issue?
If you have some old ppd for 7740 left in /etc/cups/ppd, you can substitute all 'custom' for 'customsize' and all 'Custom' for 'Custom Size' and reinstall your print queue by lpadmin like: $ sudo lpadmin -p <your_print_queue_name> -v hp:/net/OfficeJet_Pro_7740_series?ip=192.168.178.50 -P /etc/cups/ppd/<name_of_your_edited_ppd>.ppd -E If there is no ppd in /etc/cups/ppd, you can go for /usr/share/ppd/HP/hp-officejet_pro_7740_series.ppd.gz, decompress it, make changes and try to install print queue again - after this it should work even from hp-setup or gnome control center. (similar lpadmin command would work too, but gnome and hp-setup are user friendly...)
Thanks much. Updating the PPD as described fixed my problem and I was able to successfully use cups-2.2.12.
Thousand thanks @Zdenek! I copied the corresponding PDD from the old laptop, did the changes (only Custom → Custom Size), reinstalled the print queue as described and I got full control about the office printer again! Same cups version as Howard by the way. Thanks again & have great day!
