We had a similar situation. We setup a PC to be a printer server for the zebra printers. I had to purchase a software called WASP labeler V6. The programers wrote a program to transfer a spoolfile to a pc file and deposit it to an IFS folder. The Printer server monitors this ifs folder. Using the wasp labeler software it puts the proper bar code and prints the label. It took the programmer about a day to complete.
