Hi lainalex,
Thank you for using the Support Forum. Please make sure you are choosing the print entire workbook selection and that you choose the number of copies in the printer properties. If it still will not print multiple copies please try another and file to see if it is an issue with just one document. If it happens on more than one Excel document then please consider contacting your support centre for further assistance.
I am attempting to print with from Excel 2010 and have multiple copies. Say I select print 5 copies the printer will only print one copy. This is a Xerox Phaser 7800 and the PS driver through a Windows Server 2008 R2 print server.
