python 'hphack' - change display of HP printer

[Jeff]

greetings,

here's a (very) quick script I wrote based on code posted to freshmeat
(http://freshmeat.net/appindex/2000/06/22/961716715.html)

all it does is change the display of an HP laserjet printer from "Ready" to
16 characters of your choosing. it shows the basics of socket calls in
python (vs. the C version), and is very short.

if anyone has suggestions as to how the code could be improved, please mail
them to me directly or post to the list. 

I hereby release this version of the code as GPL.

-- begin --
#!/usr/bin/env python

import sys
import getopt
import socket

_RCSID = "$Id: hphack.py,v 1.1 2000/06/25 13:36:59 jam Exp $"

UEL = chr(0x1B)+chr(0x25)+chr(0x2D)+chr(0x31)+chr(0x32)+chr(0x33)+chr(0x34)+chr(0x35)+chr(0x58)

def help():
	pass

def version():
	print _RCSID

def main():
	opts, sopts = getopt.getopt(sys.argv[1:], "", [ "help", "version" ])
	for n, v in opts:
		if n == "--help":
			help()
			return
		elif n == "--version":
			version()
			return

	if len(sopts) != 2:
		print "takes two parameters: ipaddress and message."
		return

	dest = sopts[0]
	message = sopts[1]

	s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
	s.connect(dest, 9100)
	buf = UEL + '@PJL RDYMSG DISPLAY = "%s"\n' % (message) + UEL + "\n"
	s.send(buf)
	s.close()

if __name__ == "__main__":
	main()
