I need to setup a RasPi for some hardware things in a p.o.s. environment, like scanners, scale and printers (3 printers). So I took a brand new RasPi, did a complete new installation with apache2, cups and the epsonsimplecups driver, found here on youtube and here on Github and connected a thermo printer Epson TM-T88IV. Everything went without any errors, including setup CUPS for external access. Now I can print local files and over network, so good so far.
But it prints terribly slow, which doesn't mean minutes, but 10 to 12 seconds for a small receipt (.pdf) as well as a 20 lines plain text file (.txt).
May it lacking on the RasPi side, or should I test another printer like TM-T88V instead of TM-T88IV ?
Any experiences anybody ? Thanks for sharing.
