@teehaha, Welcome to the HP Support Community!
I understand the printer is printing blank pages. Let us try these steps:
Make sure the plastic tape if any is removed from the new ink cartridge before placing it in the printer.
Try making a standalone copy in black and color to check if that works. By this, we can conclude if this is a hardware or a driver issue.
Check the ink levels, clean the printhead up to 2 times, and print a print quality report as shown in this document - Black or Color Ink Not Printing, Other Print Quality Issues
Hope this helps! Keep me posted.
