To be clear, the link I posted above is for a completely different program that anyone can download to print a crossword puzzle everyday with any printer, not just web connected printers.
It sounds like you have a problem with your web connected printer. When you click on the Universal Crossword app on your printer's front panel, the screen has a "pause" option.
If you deleted the Universal Crossword app on eprintcenter, then the printer will no longer show you the app on the front panel. You have to go back to eprintcenter and click the "setup" button next to the Universal Crossword app. You should be able to change your settings so that it doesn't print out anymore.
