I have a workstation printing to a Kyocera copying machine that is on the network. When she prints from Firefox, it sends the print request to the wrong cassette. I have reset the printer information in about:config. Removed and re-installed the network printer numerous times on the workstation. The workstation is running version 27.0.1. I have 10 different workstations all on the same network running the same version of Firefox and this is the only workstation I have an issue with. Any help would be appreciated.
