I have a project that requires a barcode and other information to be printed onto a label using a Thermal Printer (i.e. Zebra, TEC)

I have a print routine that will print plain text using "Generic Text" driver and has been tested for output using Dot-Matrix printers in other projects.

But when i try to print to the Thermal Printer the data light flashes but it won't print.

Has anybody got a copy of the syntax for these printers or any other information?
