This code is not helping me print my label. The document goes to the print queue but nothing happens after that. Although the printer is correctly configured and I have successfully printed with Zebra Designer.
Also I'd like the above code such that it prints 3 labels in one row, since I have the media which has 3 stickers in one row. How can that be achieved?
My printer model is ZDesigner GT800 (EPL).
StringToCoTaskMemAnsi
, useSystem.Text.Encoding.Ascii.GetBytes
. You also don't need to start pages, you are writing raw print data to the printer, only useStartDocPrinter
andWritePrinter
