Cannot Print in Photoshop since update

Perhaps try resetting Photoshop preferences?

(read this entire post before acting please)

Resetting restores Photoshop's internal preferences, which are saved when Photoshop closes.

If they become corrupt then various issues can occur.

Here’s some info on how to do that:

Manually removing preferences files is the most complete method for restoring Photoshop to its default state:

Quit Photoshop if running.

Relaunch Photoshop and open the file that you want to print.

Press the Spacebar on your keyboard before you click File > Print. This process resets printer preferences that have been written into the image.
