Make sure your computer has enough resources to print the document in a reasonable amount of time. If the computer meets only the minimum system requirements, documents might take longer to print. For more information on minimum and recommended system requirements, see System requirements. In addition, if the computer is too busy running other programs, documents can print more slowly.

Check the device software settings

Print speed is slower when Best or Maximum dpi is selected as the print quality. To increase the print speed, select different print settings in the device driver. For more information, see Change print settings.
