Description of problem: Chromium is not able to use CUPS temporary queue for printing and enforces users to install printers permanently, even for models where it is not needed. Permanent installation of printers will be removed from CUPS 3.0 (arrives in one/two years), so if chromium is not migrated to the latest (6 years old) CUPS API, its users won't be able to print. Basically the required change is to use cupsGetDests2() for listing printers and cupsCopyDestInfo() for getting all printer options. Version-Release number of selected component (if applicable): chromium-104.0.5112.101-1.fc38.x86_64 How reproducible: always Steps to Reproduce: 0. have a driverless printer or a another machine with running cupsd and sharing queues 1. '$ lpstat -e' shows the temp queue, but '$ lpstat -a' doesn't 2. open print dialog Actual results: no temp queue Expected results: temp queue is seen and user can print to it
This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle. Changing version to 38.
it's already supported in latest 114.0.5735.198
Created attachment 1976125 [details] Chromium print dialog screenshot Unfortunately that doesn't seem to be working: This is the list of available destinations from CUPS: $ lpstat -e Canon_MF440_Series Canon_MF440_Series_USB_1 hp-m277-hplip hp-test hp-test/gray HP_Color_LaserJet_MFP_M277dw_516EE8 test tpbb-it tpbc-north tpbc-south and the attached screenshot is what Chromium shows under 'See more' when you want to choose a printer in print dialog. The temporary queues - Canon_MF440_Series , Canon_MF440_Series_USB_1 , HP_Color_LaserJet_MFP_M277dw_516EE8 - are not visible in default Chromium print dialog. Canon printer is connected by USB and by network cable, HP by network cable only. Version: $ rpm -q chromium chromium-114.0.5735.198-1.fc38.x86_64
The temporary printers are seen if user clicks on 'More settings' and then 'Print using system dialog...', which is written in GTK3 with temporary queue support, but the default Chromium dialog does not support them/show them.
