There are at the very least potential Koha users who want to use barcode generation. I have not experimented with actually using the barcode generation in Koha, myself. PREVIOUS DISCUSSION There was a conversation between owen and tim on #koha on 5 August 2005 about trying to use the barcode generator. tim seemed to have misidentified the script being called to actually generate the barcodes in referring to them as code 39, or 3 of 9. I followed his example later that night without looking at the code calling the correct script. There is in fact an old script in /intranet/scripts/misc/barcodes.pl for generating much simpler code 39 barcodes. CODE INTERPRETATION The script integrated into the Koha intranet is supposed to generate code 128 barcodes. Vault Information Services. Code 128 symbology. barcodeisland.com . http://www.barcodeisland.com/code128.phtml A useful page for understanding code 128. You might check as to whether your scanner is reading code 128 barcodes correctly. Although, it should really fail absolutely instead of giving an erroneous string. One possibility is from an online form. Carl A Sewell. Create code 128 bar code. http://home.hiwaay.net/%7Ecsewell/CreateCode128.shtml. Otherwise, try using the module used for Koha barcode generation directly. There is probably enough documentation for PDF::API to quickly determine how to generate barcodes with the module outside of Koha to use for testing. Alfred Reibenschuh. PDF::API2. http://search.cpan.org/~areibens/PDF-API2-0.45/lib/PDF/API2.pm . LIKELY PROBLEM A leading '00' would most likely be from setting the country code to USA in the template. A trailing '0' would most likely be the check digit. It would seem that something is missing or not being interpreted correctly for using that code in Koha. The intended design may be either to have the scanner not return the check digit after validating the code or some missing script is supposed to interpret the check digit in addition to the country code. PEOPLE WHO REALLY KNOW The email addresses of Veleda Matias and Castañeda Sebastian from Physics Library UNLP, Argentina, authors of the barcode generation component, are given at the top of the files such as /intranet/barcodes/barcodes.pl . A year after the barcode component was contributed it ought to be working. I would suggest contacting them to ask how the component is implemented on their system and how they actually make use of the country codes. I expect that I would use this code if it were working well and could be easily adapted to my required workflow. Thomas D Quoting Joshua Ferraro <jmf@liblime.com> :

Hi all,
Is anyone using barcode printing on a production system? I recently tried to get them working and although I can get it to produce barcodes there are two problems:
1. The file that's exported has an extension of .pl ... this means that most OSes can't determine that it's a PDF by default. What's the best way to export it as a useful filename and extension?
2. The barcodes that are generated have leading zeros and one zero after the barcode. So they're almost right, but in their current form aren't really useful (don't scan correctly).
Anyone else experiencing the same problems? Any solutions out there?
