Hello All, I have a Kyocera FS-1200 PS printer, which has been excellent for donkey's years. For a while now, can't be sure how long, maybe a year or so...the printer isn't used very much, the printer sometimes throws errors. I have spent the last couple of days trying to track down what is going on. When printing some pdf files from 'Document Viewer' in Fedora, and most pdf sent from a Win7 laptop (the printer is networked) it throws an error "ERROR: rangecheck OFFENDING COMMAND: filter STACK 120585 --nostringval--..." Pdf files that fail to print, from either Fedora Document Viewer or Win7, can be printed without error from Fedora via Xpdf. All test pages sent from the printer-config on Fedora throw the same error, the stack number varies. I have looked at the on board printer setup, and fiddled with the emulation (it can use PCL 6, KPDL 2 and others). Changes to emulation have no effect, and it always reverts to KPDL. Fedora printer-config provides a number of printer drivers for this device, and I have had it set to the recommended, and tried a few others...nothing seems to change the behaviour. Anyone have any thoughts on this? PS I did post a question on Linux Questions a few days ago but had no response, so thought it OK to ask here. Cheers, -- Regards, Terry Duell
