Find out why your printer won't print.
PrinterAI reads what your printer is actually reporting and tells you what's wrong in one sentence. Free, 1 MB, and the checking never leaves your Mac.
Searching the web can't see your printer. This can.
Type “printer won't print” into a search engine and you get everybody's problem at once, and no way to tell which is yours. PrinterAI looks at your printer — its own reported status, its ink levels, how your Mac is set up to reach it — and answers about that.
Here is what it found on the Mac it was built on, in under a second:
Nothing is stopping you printing.
Dell C1760nw Color Printer
It's switched on and I can reach it, nothing is waiting to print.
This printer is listed twice
It's one printer, written down twice by mistake. The one you're printing to is correct; the duplicate is set up wrong and would print badly.
Cyan, Magenta and Yellow are nearly empty
Three faults nobody had noticed, none of them findable by searching. That machine had one printer written down twice, the spare listing using a stand-in driver, and two cartridges almost gone since November.
What it finds
- The same printer listed twice — and which of the two is the one to keep.
- The wrong printer software, where macOS fell back to a general-purpose stand-in and pages come out wrong.
- Ink and toner levels, as coloured bars rather than a number to work out.
- Paper jams, empty trays, open covers — straight from what the printer itself reports.
- Paused printing and jobs stuck for days, with one press to clear them.
- Whether the printer is off the network — or your Mac can't see anything at all. That distinction is the one nobody can make for themselves, and it decides whether you go and look at the printer or at the router.
It won't leave you stuck
If the checks find nothing, it says so plainly instead of pretending, and then walks you through the eight things that fix most printers — one at a time, gentlest first, with a way out at every step. If those don't work either, it can talk it through with you using the free assistant that stays on your Mac — the one built into macOS. It costs nothing and nothing you type leaves the machine.
Free, and honest about it
| Free, permanently | $4.99/month, optional |
|---|---|
| Every diagnosis. Every fix. Ink levels. The eight things to try. The free assistant that stays on your Mac. No account. | The paid assistant that goes online — a more capable one, for the unusual problems the built-in checks can't settle. What you type is sent away to be answered. |
The paid tier buys a better answer, never the only answer. Nothing that works today is going behind a paywall later.
Common questions
Why does my Mac say my printer is offline when it's switched on?
Usually the printer has joined a different Wi-Fi network than your Mac — which happens after a router change or a power cut. Your Mac keeps the old address and reports it offline. PrinterAI settles this by checking whether it can see anything else on your network: if it can see your other devices but not the printer, the problem is at the printer, not your Mac.
Why does my Mac show the same printer twice?
macOS adds a second listing when it rediscovers a printer with slightly different details — after a firmware update, say. Both point at the same machine, but usually only one has the right driver, and printing to the other comes out wrong. PrinterAI spots two listings sharing one address and offers to remove the duplicate. Your printer isn't touched.
Why does my printer print blank or faded pages?
Most often an empty or badly seated cartridge, or the wrong driver. PrinterAI reads the levels your printer reports and shows them as bars, and separately warns you when macOS is using a stand-in driver rather than the one made for your model.
Does it send anything over the internet?
The diagnosis doesn't. It runs entirely on your Mac, reading the printing system's own records. No account, no analytics, no tracking, nothing collected. Two buttons open a web page and both say so on the button: looking up which cartridges to buy, and opening System Settings.
One thing does: the paid assistant that goes online. Ask it a question and what you type is sent away to be answered — there's no way to have something answer a question it can't read. It goes to our own server, and from there to Claude, which is made by a company called Anthropic. Neither of us keeps it. And there's nothing to attach it to, because there's no account. The free checks, the fixes, and the free assistant that stays on your Mac never send anything.
Does it work with HP, Brother, Canon, Epson?
It reads the standard status vocabulary every modern printer uses, so it should. Being straight with you: it has been tested hardest against a Dell on Wi-Fi. If yours reports something it gets wrong, the app can save a record of what your printer said — containing nothing about you — and that record becomes a test.
