ZPLII thermal label not printing Fedex web services

Question

I have a c# app that connects to FedEx webservices, and want to print a shipping label on a thermal Zebra printer. I request the response to be in ZPLII type and save that response to a .txt file. I have talked to Zebra and FedEx and they both say that this should work. I use a generic print driver to connect to the zebra printer and still the printer is printing out tha actual characters of the txt file, not converting it into a label. Are there any characters that I am missing that FedEx does not automatically iunclude - like maybe a 'start print' , 'end print' character? Or does anyone have any idea to get this txt that I am recieving from web services to print? here is ZPLII response:

^XA^CF,0,0,0^PR12^MD30^PW800^POI^CI13^LH0,20
^FO12,139^GB753,2,2^FS

^FO224,10^AdN,0,0^FWN^FH^FD(408) 986-4804^FS

I cut out the middle, I think the begining and end are the important parts, since the printer is not converting this text into a label

Answer 1

It turns out my ZPL II code is fine. If anyone else comes across this , as far as I know - from what everyone has told me you cannot connect to a clients printer to send raw data to it from a c# web site or from any c# web app. The solution is to use either a java applet, flash, or silverlight to connect directly to the clients computer. I used jZebra java applet that communicates with jQuery front end and c# back end.

Answer 2

I usually just send the raw data to the printer port as a fileCopy (I.E. Filecopy "c:\Label.txt" \computer\printersharename)
