Finally made it back to my desk. Here’s a chopped down version of what I use.
from java.net import Socket
from java.io import DataOutputStream
partnum = 'ABCBEFGH'
serialNum = '12345678'
strMessage100 = "^XA"
strMessage110 = "^BY3,3,60^FT065,120,^BCN,N,N,N,N^FDP%s^FS" % partNum
strMessage111 = "^FT170,040^A0N,40,45^FD%s^FS" % partNum
strMessage112 = "^FT065,260,^BCN,N,N,N,N^FDS%s^FS" % serialNum
strMessage113 = "^FT170,170^A0N,40,45^FD%s^FS" % serialNum
strMessage199 = "^PQ1,0,1,Y^XZ"
strOut = strMessage100+strMessage110+strMessage111+strMessage112+strMessage113+strMessage199
printerIP='192.168.140.61'
port=9100
try:
# Open Socket Connection
clientSocket=Socket(printerIP,port)
#Open data output stream
outToPrinter=DataOutputStream(clientSocket.getOutputStream())
#Send Data to Printer
outToPrinter.write(strOut)
#close data stream and socket
outToPrinter.close();
clientSocket.close();
except IOError:
print "Error", row
