I ran into my first major hiccup with Yosemite, I can't print from my iMac. The printer is a Kodak ESP 9250 connected over our wifi network. What happens is a page starts to print then it gets held up, like a paper jam but there is no jam. If I pull up the printer queue, an error shows up, check printer and try again, and a error number 100305. If I cancel on the printer, the printer ejects the page and the queue shows an error "Filter" failed, and a popup in Yosemite says that the printer driver quit unexpectedly. What I have tried is removing the printer in the Printers and Scanners section and re-adding (several times), uninstalled the Kodak software and reinstall, and rebooted and re-added the printer, nothing helped. I checked Kodak's site and I'm running the latest drivers and software. Using the scanner from the Mac works normal and copy-print from the printer works normal as well.
