Yup, reportlab has really good barcode generation stuff. I use it to generate labels with barcodes on for asset tracking :-) http://the-gay-bar.com/index.php?/archives/221-Howto-generate-barcodes-in-Python-with-reportlab/ Chris -- Simplistix - Content Management, Batch Processing & Python Consulting - http://www.simplistix.co.uk -- http://mail.python.org/mailman/listinfo/python-list

Re: Barcodes
My company needs a small inventory management app. Does python have any libraries to help with reading and writing bar codes? I've written bar code apps and python really doesn't enter into that part of things. Printers generally have bar code printing capabilities so you just send the right escape sequences and you get the bar codes. To read them, bar code readers scan and translate before sending the values through typically a keyboard wedge or serial port. To add to what Emile mentions, most barcode readers present a keyboard-wedge interface, so that scanning a barcode merely appears as if you typed it at the keyboard (USB readers show up as a HID profile). Often they'll have configuration barcodes that you can scan to tweak the profile (such as pressing , or an arrow-key after sending the barcode; controlling beep tone & volume, etc). For printing barcodes, you can use any number of solutions -- the most popular usually just involves installing a "barcode font" and then rendering text in that font to your desired output canvas. I believe there are some native rendering solutions as well, but I've not investigated since the font method was more than sufficient for my wants. -tkc -- http://mail.python.org/mailman/listinfo/python-list
