direct output to printer

[Uwe Schmitt]

Hi,

I'd like to print barcodes with a special barcode printer.
Therefore I have to send raw ASCII data to the printer.
How can I do this using Python under Windows ???

Greetings, Uwe.

there is a raw print function in win32all, but i haven't used that. for the
barcode-printer i used, i sent a bitmap with the barcode. that way you can
print the same barcode on paper or preview on the screen (i used wxPython).

there are some free barcode fonts around. i use this one:

Same way you'd do it in MSDOS
(if you have it connected to a parallel port):

>>> lpt = open("lpt1:", "w")
>>> lpt.write(BarcodeDataString)
>>> lpt.close()

You can also use "prn:" instead of "lpt1:"

pd: Win's just MSDOS with icing on top. ;-)
