Printing Barcodes

Hello all,
We are in a similar situation where we need *generic* Barcode print
capability, i.e. To print Barcode to *any* printer supported by CUPS without
dependence on hardware support or fonts.
I have cooked a solution for this - it is near completion - but I need to
figure out the right / elegant way to integrate into CUPS' filters.
My initial thoughts:
1. Send, with the job, an attribute (option): barcode=type;left-x;lower-y
e.g.: lp -o"barcode=code39;50;150" text_with_barcode_marks.txt
2. In the print file place a mark: ESC B 0123456789 ESC B
ESC is 0x1b, spaces are for readability and the data follows.
The mark can be placed anyware in each page that contains a barcode.
3. Hack texttops to recognize the ESC B sequence. texttops will treat it
as zero length.
I would appriciate (very much so) comments.
Thanks,
Opher Shachar.
