Hello Mark, Welcome to the forums!:)
I noticed your post about your Photosmart C4280 printing out blank pages. I saw that you have also tried another printer and the issue also happened with the other printer. I would suggest test printing from another computer to see if the issue occurs, as this seems like it could be a software problem on the computer. I do also suggest trying a copy from the printer itself just to make sure it copies okay before troubleshooting any further. A copy will test the printer functionality.
If the copies are ok, lets move on.
Run the HP Print and Scan Doctor to search and fix common printing problems.
Try printing from the program that was printing out blank pages, and also try other programs, such as Notepad. This will show us if the problem is within the printer driver or the software program being used.
If the issue still persists, please let me know any more details, such as error message on the printer or computer, if you were able to print from another computer and if it was successful, the results from the Print and Scan Dr., and if you are still printing blank pages from more than one program and what programs you are using to print from.
Thank you,
