how to send control codes via "???" to receipt printer

Hi All,
I am writing a POS system and using a receipt printer (Epson TM-U220D). Unfortunately the printer drivers from Epson didn't work & hence I resorted to using the Windows Generic/Text printer. I am using a series of to output to the printer, which works fine. My problem is that I need to do some form of simple formatting on the receipt, e.g. make company name bold, etc. My question is, how do I send the control codes to achieve the above

Thanks all.

    Look at the printer manual for the codes you need and sendt hem as CHR(x).

    e.g.
    CHR(15)+"This is some text"

    Hi,

    additionally to the direct embedding of that CHR() codes, the command has a lot of Macros like

    "{ESC}A This is plain text {Ctrl+A}Something different"

    For a more indept list (which is not in the helpfile),

    Another possibility is to include the printer code in curled braces:

    "Plain text, {27}{69}bold{27}{70}, plain again"

    This syntax is the reason why you need to print curly braces as "{123}". 123 is the ANSI code for "{".
