How is the printer connected to your computer (network, USB, etc.)?
Does this happen with specific programs or all programs?
When did this start happening (how long ago, any specific changes like cartridges, etc.)?
I have included a general slow printing guide from HP. I recommend following all steps except for the ones that do not apply. For example, if it is wireless then you would ignore any USB or Ethernet steps.
I noticed PrintDoc has a solution that works fairly often if is connected over a network here.
