Office XP

My client had a Win98 Box with Office 2000 and a HP 950 DeskJet.
I upgraded his box to a P4 and he wanted Office XP instead of Office 2000. I gave hime a freah Win98 box and loaded Office XP and transfered all his data files only.
He can view and print his word files that were created in Office 2000 to his local printer, but cannot print his excel files to his local printer. He can print them to a network printer (HP 656 usb)but not to his local printer(HP 950 DJet). If he created a fresh spreadsheet using Office XP it prints out fine on his local printer.

Please help!
