HP printers is offline or unavailable

HP printers (OfficeJet Pro, ENVY, DeskJet, LaserJet Pro and Smart Tank) is offline or unavailable: prove the printer can print internally before repairing the network or computer queue. Scoped to OfficeJet Pro 9135e (404M0A), with the other HP OfficeJet Pro, ENVY, DeskJet, LaserJet Pro and Smart Tank models in the model notes.

HP's offline article is a short ladder, and the order matters because each step is cheaper than the next. First restart everything: turn the printer off with its power button, or pull the power cord if it will not turn off; restart the computer or phone you print from; and if the printer is on your network, restart the router. If the printer is on wifi, disconnect the computer or phone from the network name and reconnect it to the exact name the printer uses,

The checks in more detail

since a device on a different band, a guest network or a mesh node can look like an offline printer. Plug the printer straight into a wall outlet, as HP recommends, and check the wireless light on the control panel: solid blue means connected. Second, run Diagnose & Fix in the HP app on Windows or macOS: open the app, click the printer, choose Diagnose & Fix, click Start and let the analysis finish without closing the app, then follow the results.

Third, remove and re-add the printer: in the HP app, click the printer, scroll to the bottom and choose Remove from app, then Add Printer and repeat setup with the printer on the same network as the computer or connected by USB. Advanced steps in HP's article cover updating the printer firmware and resolving offline status in Windows or macOS settings, where the printer entry can be set to use the wrong port or an old address.

If the router changed, the printer's address may have changed too, so print a network report and compare. It also helps to give the printer a fixed address in the router's settings once it is working, so that a router restart cannot move it, and to keep a note of the printer's network name and IP address from a network report. Many offline problems return after a router change, so that note saves time later.
