Print42 - thermal printer software for Free42

[tcab]

Hi - great to hear about your thermal printer purchase!

Before I go to the effort of making a linux version of Print42, we need to verify if your bargain printer responds properly to ESCPOS commands and is compatible with the python escpos library that Print42 uses, https://python-escpos.readthedocs.io/en/latest/.

Please install the escpos python library with

Code:


pip install python-escpos==3.0a4

You need to know your printer's vendor and product id e.g. the values for my epson are
"vendorid": "B000",
"productid": "0410"

Then use something like this code to see if it communicates with your printer:

Code:


from escpos import *
x = printer.Usb(0x04b8,0x0202)  # replace with your own printer's vendor and product id
# Print text
x.text("Hello World\n")
# Print image
x.image("logo.gif")
# Print QR Code
x.qr("You can readme from your smartphone")
# Print barcode
x.barcode('1324354657687','EAN13',64,2,'','')
# Cut paper
x.cut()

cheers,
Andy
