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.

  • PS.: I also installed a DYMO LabelWriter 450, and it works fast as expected, including a number of copies. – ddlab Oct 4 '17 at 8:30
  • Have you tried setting your printer as a RAW printer? – Dr.Rabbit Oct 4 '17 at 9:07
  • PS2.: I gave python a try, using python-cups and a python script with printing commands. It's working, but with same results, prints slow. – ddlab Oct 4 '17 at 9:10
  • @Dr.Rabbit Yes I did, it's printing fast, but it doesn't print my .pdf, which is generated on the server. Instead I got 3 meters garbage paper :-) – ddlab Oct 4 '17 at 9:12

    Hmm, maybe try something like python-escpos in conjuntion with pdf-miner – Dr.Rabbit Oct 4 '17 at 9:32

I tried the package from plinth666 but the raster wasn't quite proper and the print timing waas quiet long.

I used then a bunch of free code from Epson, a PPD file from another printer and modify them to produce this new package: https://github.com/groolot/epson-tm-t88v-driver

Better rasterization, cash drawer and buzzer, all is operational.

Hope that could help someone like I was: in pain.
