I just installed a brand new HP DeskJet 9650 printer on all our office workstations. Mine has AutoCAD 2002; the others have AutoCAD LT 2002. The printer error message, "Printer name is invalid," occurs only on my machine, and it occurs each time I try to print to the new printer or to any other previously installed printers, which used to work fine. Although the error message is displayed, I can still print to the selected printer just fine. How can I correct this nuisance?
