To guard the printer at work.

When you have printed something you know you shouldn't have, using your office's printer/ink.

You then guard the printer while your paper is being printed so that no one else can accidentally grab your paper. Which could result in embarrassment and/or reprimanding.

Also "Printer Anxiety":
While you are Printer Guarding, you may experience Printer Anxiety because (a) You have printed something long and it is taking forever. (b) Your paper has gotten jammed. (c) Someone is printing at the same time as you, so you both are standing near the printer, awkwardly.
Office Girl 1- "Wow, that was sketchy, I just got done printing 13 pages of my coupons, in color!"

Office Girl 2- "So what?"

Office Girl 1- "So, I had to Printer Guard for like 20 minutes while it was printing!"
