CUPS support

Can we send data to cups server and print from there instead of usb or serial? I tried Network but seems not working. I also tried PR#348 but failed-perhaps it is incompatible for today’s python-escpos.Any solutions?

I use pip install -U git+https://github.com/belono/python-escpos.git@f07d5e06109e37aa45a5a139f49f56d6399b98d3 instead of pip install -U git+git://github.com/python-escpos/python-escpos/pull/348/commits/f07d5e06109e37aa45a5a139f49f56d6399b98d3. Pip failed to clone pr via git+git://, so I used the former one. I made some changes to your code (constructor of CupsPrinter(Escpos)) to enable connecting to remote CUPS server:

def __init__(self, host=None,port=None,printer_name=None, *args, **kwargs):
            Escpos.__init__(self, *args, **kwargs)
            if host!=None:
                cups.setServer(host)
            if port!=None:
                cups.setPort(port)
            self.conn = cups.Connection()
            self.tmpfile = None
            self.printer_name = printer_name
            self.job_name = ''
            self.pending_job = False
            self.open()

And according to your instruction I ran

import escpos.printer as printer

cups_conn = printer.CupsPrinter(host="192.168.2.1",port=631,printer_name="XP-58IIH")  # Default CUPS printer
cups_conn.textln("Hello CUPS!")  # or any python-escpos command
cups_conn.close()

It works!

Here are detailed info of my devices. Hope they’re useful to you.

CUPS server: raspi zero w, Linux raspberrypi 5.15.32+ #1538 Thu Mar 31 19:37:58 BST 2022 armv6l GNU/Linux Printer: XP-58IIH print request sender: an simple armv7l device based on armbian
