POS Application, printing control fonts (possibly using WORD API)

[jeweladdict]

In order to open a cash register hooked up to my receipt printer, I need to send 'G' using the CONTROL font to the printer. Using PrintDocument does not work because all of the text gets turned into a picture before it gets printed and so the printer does not recognize the special font. The printers are on USB and Ethernet and so it's not as simple as sending a code over the desired port... how do I actually send the string to the printer? One way that I think will work is if I send a string to a WORD document with the specified font and print it (with visibility set to false to make it transparent). Can someone point me in the right direction to do so? Thanks!
