You need to Add escape Chars to do your job.
Like
Chr(27) + "E" for Normal Bold face on
Chr(27) + "F" for Normal Bold face off
Chr(27) + Chr(14) for Double soze bold face
Chr(27) + Chr(18) for Double soze bold face off
etc.

Check printer documentation or Search Google for Printer escape Chars for more chars

Solution 1

To print without a print driver, you'd have to communicate directly with the parallel port, I'm not sure if there's a standard for that or if you'd need the manual for your printer.
