ID Card Printing Under Linux?

peng1can asks: "I'm searching for a way to print ID cards in a an LDAP and preferably open source environment. We use LDAP heavily, and ideally we want to be able to pull user information and photos from LDAP and print onto ID Cards. Thus far, I've come up against two roadblocks: 1) Trying to make the ID station work under linux would be great, especially if I can script gphoto. But, I can't find an ID-card printer that doesn't supply windows-only drivers. The closest thing I can find is that Eltron provides a programming manual for their printers, but I have no knowledge of how to write a CUPS/LPRng printer driver. 2) If we had to resort to a Win-based workstation, I can find no method for accessing LDAP in a way that would work with an ID card system without spending thousands of dollars per station on an LDAP/ODBC gateway. I could try to write something in PERL for Win32, but can't find a way to control a digital camera that way. Any suggestions would be greatly appreciated."
