Printer prints nothing on paper.

[Moonepie]

My printer goes through all the motion like it's printing something, but spits out blank papers.  I have ink and paper in the printer.  No error messages pop up telling me to replace something.  I've used their automatic trouble shooting app and it says everything is fine.  So what gives?

What printer model are you referring to?

Was the printer unused for a longer period?

I'm using the HP Envy Inspire 7900 series, and yes the printer was unused for a little while.

Ink dried because the printer was unused, you will need to install new fresh ink cartridges.

Thank you!  I changed out the cartridges and the printer now works.  Thank you so much!
