You need to explain what error and state what the status shows in Command Workstation.
And realistically, what OS, version of Excel, how you are selecting what sheets to print etc etc.
A link to the excel file wouldn't hurt either.
We have a C60 with Fiery. When we try to print multiple Excel sheets (2-3 sheets are selected), the first sheet prints but the other sheets error out and do not print. Anyone have any suggestions?
