EPL2 language

  • The Eltron or Zebra printer needs to be installed with a RAW driver/queue. If stuff doesn't print right, check that first.
  • Each command sent to the printer needs to end with a LINEFEED only (\x0A). You can't just use '\n' or '\r'
  • The bare minimum to print a label:
N\x0A
ZT\x0A
P1\x0A
  • Because the GW command requires BINARY data, you can't view the file with a text editor. You'll need to use a HEX viewer to see the actual contents
  • The image format is pretty specific. PCX is almost extinct but Gimp or IfranView can export to that type. The image should report Colors: 2 (1 BitsPerPixel). GRAYSCALE won't work, thermal printers only have 1 shade of gray.
  • It's possible some of the image (the last column of pixels) will get chopped if it doesn't end in a proper byte
