I suppose should be really specific and say, is that an ethernet (or WiFi) connection between printer and router, or is the printer connected to a USB port on your router (which may entail fun and games as how the router presents a printer to the network). > I need the Epson driver for Fedora and Ubuntu as cups has no support > for my device whatsoever.

I can't recall you saying what the printer actually is. You've said you've installed an Epson driver, perhaps it doesn't name itself in a unique manner? Perhaps it's not really a printing "driver", just making it appear to the system? If the printer directly accepts PostScript, PDF, or one of a few common languages, perhaps CUPS does the actual print driving. > None of these drivers impress me with their level of support for the > printer.

A lot of printers are just 600 dpi printers, with software doing some pretending to make the printing look crisper. Selecting paper types may make no noticeable difference, it depends on what the printer does with the information, it could affect any of: Changing dithering patterns, slightly changing distance between the print head and the paper, changing drying times, which inks it uses, changing toner temperatures, simply selecting the right paper tray to print from or too (e.g. cardstock requiring a straight through path), offering/refusing double-sided printing, the range of print resolutions it offers. I distinctly hate having to deal with printers. Firstly you have to get it working, which can be a nightmare, even on their supported OSs. A year or two after getting one you may find it impossible to get ink or toner, or it's become ridiculously expensive. Or they only supplied a badly working driver for an old OS that can't be used on a newer one. -- [tim@localhost ~] -rsvp Linux 4.13.16-100.fc25.x86_64 #1 SMP Mon Nov 27 19:52:46 UTC 2017 x86_64 Boilerplate: All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I only get to see the messages posted to the mailing list. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
