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.
If this solution does not resolve the issue, you can read discussions and post messages and questions relating to your issue on the Intuit QuickBooks Community site. You can also review other available QuickBooks support options for additional guidance.
