I can not print with my HP Deskjet Ink Advant K209a-z

Hi,

To begin with, it may be a good idea to reset the printing system. Does the operating system offer a suitable driver to use?

If not, check whether the Dec 11, 2020 HP Printer Drivers v5.1 for macOS (https://support.apple.com/kb/DL1888?viewlocale=en_US&locale=en_US) package download from Apple would work. Try something like the HP Deskjet Ink Advant K209a-z version 3.3.2 driver mentioned in the Printer and scanner drivers for Mac - Apple Support article.

If necessary, you may want to have a look at the HP Easy Admin tool for Mac (https://support.hp.com/us-en/document/c06164609) that allows administrators to download drivers without a connected printer.

Before testing printer drivers, make sure that you have backup copies of all important files (documents, photos, et cetera).
