HP OfficeJet Pro 7740 shows that it is printing with load symbol, but does not print

Printer: HP OfficeJet Pro 7740 Wide Format All-in-One

I have tried printing multiple document types from my laptop via wireless, also emailing directly to the printer and via a usb stick.  In all cases, the screen shows that it is printing with the loading symbol, but nothing prints.  Printing will only occur when printing the printers instructional information built into the printer directly from the printer. I have turned the computer on and off, unplugged it, restarted my computer, and installed and ran the print and scan doctor.  Problems were noted and fixed by the print and scan doctor program, but the problem persists.

I have not yet tried uninstalling and reinstalling all the drivers as it is not clear which ones I should be uninstalling and reinstalling.  If this could be the issue, directing me to how to properly do this would be helpful.

Also, if there is any other trouble shooting suggestions I would appreciate it.

Thank you!

• Under print server properties, go to drivers - remove any entry there as well.
