Please do the following tests and tell in which cases you get useful printouts (and if so, also tell whether there are quality differences, the PPD files are ones which you had attached in comment #2, file.pdf is an arbitrary PDF file): lpadmin -p oldppd -E -v ipp://EPSON25B56D.local:631/ipp/print -P EPSON-WF-3620-Series17-04.ppd lpadmin -p newppd -E -v ipp://EPSON25B56D.local:631/ipp/print -P EPSON_WF_3620_series17-10.ppd lp -d oldppd -o cupsPrintQuality=Draft file.pdf lp -d oldppd -o cupsPrintQuality=Normal file.pdf lp -d oldppd -o cupsPrintQuality=High file.pdf lp -d newppd -o cupsPrintQuality=Draft file.pdf lp -d newppd -o cupsPrintQuality=Normal file.pdf lp -d newppd -o cupsPrintQuality=High file.pdf For these tests please also follow the instructions of the section "CUPS error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1712019 Title: Driverless printing only prints a blank sheet 17.10 Status in cups package in Ubuntu: Incomplete Bug description: Driverless printing works perfectly in Ubuntu 17.04 with my Epson WF 3620.
