I’m triyng to use the code on the link bellow but it doesn’t work’s.  
[inductiveautomation.com/forum/v … =70&t=9727](https://inductiveautomation.com/forum/viewtopic.php?f=70&t=9727)  
I have a cab PX4L \300 Printer to print Labels.

You can see my code bellow:

#========================================================================================

# cab PX4L/300 commands

#========================================================================================  
strMessage = “t0/n/r”

#========================================================================================

# Import Socket Library

#========================================================================================  
import socket  
#========================================================================================

# Get Printer IP

#========================================================================================  
strIP=‘10.11.91.33’  
#========================================================================================

# Send Data to Printer

#========================================================================================  
port=9100  
try:  
# Open Socket Connection  
clientSocket=Socket(strIP,port)  
#Open data output stream  
outToPrinter=DataOutputStream(clientSocket.getOutputStream())  
#Send Data to Printer  
outToPrinter.write(strMessage)  
#close data stream and socket  
outToPrinter.close();  
clientSocket.close();  
except IOError:  
print “Error”

Please, check the message that appears:  
Traceback (most recent call last):

File “event:mouseClicked”, line 21, in

File “event:mouseClicked”, line 21, in

NameError: name ‘Socket’ is not defined

Ignition v7.7.4 (b2015033012)  
Java: Oracle Corporation 1.8.0\_65

I don’t know how can I solve that problem. Could you help me???  
Regards,  
Leandro

“Socket” is not defined because the Library is called “socket”, case sensitive.
