Hey There, I am Sofia Carter. If an HP Printer Not Printing, try these solutions. Make sure that the network or cable you use to connect your devices is appropriate and that all of your devices are properly connected to one another. The HP printer can also be restarted. Give it some time to cool after turning it off entirely and removing the power cord. After inserting the cord back in, turn the printer back on. Alternately, you might need to update or reinstall the printer driver to fix this issue.
