I was able to reproduce the bug with the IPP printer emulation utility ippeveprinter (package cups-ipp-utils).
It is actually 2 bugs: One is that cups-browsed (which automatically creates a CUPS queue for your printer) sends PDF and not Apple Raster to your printer, and your printer is slow on processing the complex PDF format. I have done a fix on the upstream code now that if the destination printer supports both Apple Raster and PDF, the former gets preferred. This way the computer and not the printer renders and rasterizes the PDF input, and the computer has usually a much higher performance for doing this work. Upstream fix in cups-browsed: https://github.com/OpenPrinting/cups-browsed/commit/3eb66da The monochrome output is due to a bug in the PPD file generator for driverless IPP printers. If the printer reports "auto" as default for the color output mode, it selects gray instead of RGB as default. This I have fixed in libppd now: https://github.com/OpenPrinting/libppd/commit/1934a6c341 These fixes will be included in the next uploads of libppd and cups- browsed. ** Changed in: cups (Ubuntu) Importance: Undecided => High ** Package changed: cups (Ubuntu) => cups-browsed (Ubuntu) ** Also affects: libppd (Ubuntu) Importance: Undecided Status: New ** Changed in: libppd (Ubuntu) Status: New => In Progress ** Changed in: libppd (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/2014976 Title: CUPS doesnt work anymore with my HP Printer Status in cups-browsed package in Ubuntu: In Progress Status in libppd package in Ubuntu: In Progress Bug description: With 22.10, the autogenerated PPD has much more info inside then with 23.10.
