I HIT THE PLU/SUB HOW DO I STOP THE PRINTING? PLEASE..TY

Don't know that model as it isn't a UK one, but normally it will just print out your PLUs if you hit that.
Not much you can do with XE-As to stop things (no program reset apart from taking the batteries out), so you'll just have to let it run.

Hello and thanks for the fast reply..this did happen before and my neighbors friend was able to press some buttons and stop it, hes trying to contact his friend to ask him what he presses and im growing impatient..lol...but i know there is something you press and it will cancel the printing...

I actually managed to find a manual for it, but I'm still none the wiser how to stop it!

Found it in very small writing! Here's what it says:

To stop reading programming report 1 or PLU programming report, turn the mode switch to the
MGR position
