We have an HP 4250 printer that just started showing a 49.4C02 error today. Looking around online, it looks like everyone says it has to do with Adobe or other PDFs but this printer is doing it no matter what I print. I've power cycled it, cleared the print queue but nothing has fixed it. I've tried printing Word documents, test page, etc. but every time I do, it immediately gets the 49.4C02 error.
