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.

Low ink levels

Check the estimated ink levels in the ink cartridges.

NOTE: Ink level alerts and indicators provide estimates for planning purposes only. When you receive a low-ink alert, consider having a replacement cartridge available to avoid possible printing delays. You do not need to replace the ink cartridges until print quality becomes unacceptable.

The ink cartridges might have insufficient ink. Insufficient ink may cause the printhead to overheat. When the printhead overheats, the printer slows down to allow it to cool.

NOTE: Turn off the HP all-in-one by pressing the Power button located on the product. Wait until the Power light turns off before unplugging the power cord or turning off a power strip. If you improperly turn off the HP all-in-one, the print carriage might not return to the correct position causing problems with the ink cartridges and print quality issues.
