[SOLVED] Brand new printer won't print

[absolutezero1287]

I recently bought an HP F4280 and I upgraded hplip to the latest version.
My printer was recognized but whenever I request a print job it says that it has been completed. However, my printer doesn't actually print anything.
Here is the output of hp-check. Please help.

Among the many errors in the output you linked is this:

#
warning: Printer is not HPLIP installed. Printers must use the hp: or hpfax: CUPS backend to function in HPLIP.

Install hplip-gui and install the device using that interface.

I installed it via the CUPS web interface and was able to print a test page.I was also able to print a pdf of a lecture on Single Variable Calculus from MIT's OpenCourseWare site.

I guess that it's safe to say that it's installed.
Thank you very much for all your help.

One more question: I have the HP status device and HP device manager installed. The device manager doesn't detect the printer. Is it safe to remove it?

Solved. Uninstalled HP toolbox and it still prints without a hitch.
