The laptop prints fine at home and goes blind in the office — or the other way around. Nine times out of ten it’s one rule nobody told you. Here it is, plus the exact steps.
A computer can only print to a network printer that is on the same network as the computer. Same network, visible. Different network, invisible — not broken, not personal, just geography. Nearly every “my laptop won’t print” story is this rule wearing a disguise:
Windows 10: Start → Settings → Devices → Printers & scanners → Add a printer or scanner, then the same idea.

Don’t start by typing addresses — that link is the deep end. Nine times out of ten, not-listed means your laptop and the printer are on different networks (checklist, step 2) or the printer is asleep/off. Fix the network first; the printer usually appears on the next search like it was never gone.
Totally normal, and it works the way you’d hope: the laptop remembers each building’s printer. At the office, choose the office printer; at home, the home one. The one trap is the default printer: Windows likes to make the most-recently-used printer the default, so the first print of the day in a new building can head for the other building’s printer and appear to vanish. If a job “printed but nothing came out,” check which printer it went to before reprinting five copies for the other building to find.
And the question hiding under this whole page — “Can I print to the office printer from home?” — plainly: no, not without the office’s private tunnel set up (the same one the sharing guide, Part 7 uses for the books). A network printer answers only inside its own building. That’s a safety feature wearing an annoying hat.
