After an Adobe upgrade, PDF's cant print to Sharp 450 models. Simply says "the document can't be printed" However, if we check "Print as Image" it's prints with no errors. This issue is printer specific because pdf's are able to print ok to other Sharp printers on the network. Clients are running Win XP Professional. We have uninstalled and reinstall Adobe and we have the updated 450 driver from Sharp. Has anyone seen this specific issue, or at lease with other printers. Thanks for your help.
