Welcome to the HP Support Community. I'd be happy to assist you with the slow printing issue.
To better assist you -
1) How's the printer connected - wired or wireless?
2) Are you experiencing this issue while making a copy as well?
3) What's the application that you are printing from?
4) What's the paper size and type? Check the print driver settings. Selecting certain paper types or printing in Best or Maximum DPI quality can slow print speeds. Print with plain paper in Normal or Draft quality for faster print speeds.
