[Koha] patron list and printer driver

Hello, I am the director of a small public library and run koha on Ubuntu Linux. I am having trouble printing a list of registered borrowers. For some reason, when I pull up the list of "members" they will all display on the screen but only two pages worth will print. Any clues? Also, I really would like to be able to use my old slip printer with koha. Has anyone written a Linux driver for slip printers? Ours is a Citizen, model iDP3550. I know of another library with a similar printer, that is considering switching to koha, but won't do it without their slip printer. If anyone wants to tackle this, I'd be really grateful. Thanks, Kim Olson Auburn Public Library auburnpl@iowatelecom.net
