I ran a bunch of updates on my Manjaro Linux laptop and noticed that printing from the laptop stopped working – this is the same setup where I was happy with how easy the setup was to print wirelessly to my MP620.
The issue turns out to be the update doesn’t automatically update CUPS configuration to use the latest postscript printer definition (ppd) file – if you see the error “The PPD version (5.x.x) is not compatible with Gutenprint 5.y.y. Please run `/usr/bin/cups-genppdupdate' as administrator.” this is almost certainly the problem.
The fix is to go to the CUPS admin page – open your browser to localhost:631 – then Printers > Your Printer > Modify Printer (In the Dropdown) > Continue > Continue > Pick the new MP620 Driver from the List > Modify Printer > Type root and password when prompted and your printer should be working again. Hope this helps if you ran into a similar problem.
Thank you very much for this info!
I’d like to add that I have an Epson Stylus SX535WD, which wasn’t listed at the “pick new driver” stage. I selected the closest (SX535FW) and it works.
