some 20 years ago, when I bought a new printer, I used to "pixel-play" with it: Try printer commands, see how far I can push it using the highest possible resolution, see how fast I can print graphics ...
So, recently I had to bury my loved HP-LJ 4M (600 dpi laser) and bought an Epson ET-M1140 (1200x2400 ink) and I'd like to see what I can do with it. First I bought different types of paper and tried paper handling, two sided printing and such. BTW: Once I used to work as an DTP operator.
Now, how can I try out printing in 1200x2400 dpi? Since angled lines look kinda "stairy" I guess CUPS doesn't use the printer's full capabilities. So, what to do?
Any hints anybody?
TIA

PPS: Inkscape is faulty. It doesn't really embed images. So, here you are: http://test.szaktilla.de/scheibe1.png

Start by examining the available printer options (as reported by the printer or associated PPD).
I changed the print quality in some way - well, at least printing takes more time now.
But it didn't change any resolution aspects. Circles, angled lines, text and so on still show some kind of „saw tooth“ edges. Now grey areas don't show „line feed stripes“ as it was before but text/bitmaps still look like 300 dpi (ugly for someone like me). It seems that there simply doesn't exist a way to change the resolution to something other than 300x300 dpi - so to me it seems that Epson has some major problem with their printers under Linux/CUPS. Looking at this problem with my DTP operator's eyes it is a really HUGE problem.
And searching the Epson Homepage I didn't find out how to tell/ask them about it. Huh?! Don't they offer any support?
Even the most recent version of Debian 11 doesn't support this printer in any way other than use it with the driver for the (older) ET-M1120 ...
