Some printers and/or printer drivers accept a setting for multiple copies, but do not actually print multiple copies.
For this reason, the QuickBooks WPR.INI file contains the Copy Fibs section. If a printer is listed here, the program will print extra copies rather than leaving it to the printer driver.
Solution: Add the printer to the [Copy Fibs] section of the WPR.INI file
Note: The printer name must be identical to the name in the Windows Printers and Faxes window.
