I am VERY excited about this open source printer project. We are pretty light users of our HP inkjet printer, so much so that we've had ink cartridges dry on us, forcing replacement. The ability to refill cartridges would mean that I'd be able to set up a cron job to do a test print every once in a while to keep the cartridges from gumming up.

Not to mention being out from the "phone home" DRM/auto-update bullsh*t.

@pluralistic would be proud

@knasman @pluralistic Supported paper formats
North American letter, tabloid, and 11-inch wide paper roll
European A4, A3, and ***27 mm-wide*** paper roll

I suspect "27mm" is a typo, but I also hope they don't really mean "27 cm-wide", because 27 cm is not wide enough to allow A4 landscape. That would require 297 mm (11.7"). The missing 9 is probably the typo.

@winterknell @knasman @pluralistic the ISO paper sizes aren't really just European - they're international, just that USA seems to still also use traditional paper sizes. (I've seen US companies that use A4, and it's possible but rare to source 8.5"x11" paper in Europe.). Back in the 1980s, a lot of European users of dot matrix printers used fanfold 8.5"x11" paper because the software at the time of US origin didn't think A4 was a thing.

@zymurgic @winterknell @knasman @pluralistic Still have most of a carton of fanfold from ~1985-86. It’s surprisingly good quality paper, which separates to true A4 (after stripping off the two tractor-feed strips). The tractor feeder for my Juki 8100 was too expensive for me.
