This error happens primarily on windows 7 (both x86/x64) but we've seen it on windows 10 before. It pops up dozens of times and it is possible to end the process in task viewer but still impedes printing. We have tried installing drivers from the printer's utility (XeroxSmart Start) with the same issue. We have tried universal pcl and ps drivers. We are pushing some drivers through gpo but even the manually installed ones do this for these users. Any tips would be awesome! Thank you in advance!
