Getting a networked printer hanging off an Ubuntu server to print
Notes to self:
In this case, a new PPD had to be used (on the client machine), since the old one magically and suddenly stopped working. Very non obvious and a reminder that Linux is still the land where you sometimes are faced with complexity that makes it similar to IT consultancy work just to print something.
The printer is a HP LaserJet M1522n MFP hooked up to an old laptop that functions as a printer server, with the printer shared on the network; I changed (on the client machine not the Linux server since that one printed fine) to a driver with a different suffix somewhere at the end of it all (the full name that is).
