Not work in Zebra 220XiIII Plus (300dpi) printer

Dec 12, 2008 at 5:47 PM
I am wondering why I can not use this dll to print the bar code. The printer is Printer: Zebra  220XiIII Plus (300dpi). I use this by TCP/IP. When I tried to print a bar code using the example of source, nothing was be done.
So, could you give me some ideas for this pinter?
Thanks!
