I have an HP 6835 printer that will not Airprint (iphone does not see it) Why not?

Hi,

Have you checked that the printer and the iPhone are connected to the same Wi-Fi network (router)?

If all settings are OK, you could perhaps try the following power-cycling sequence: Power off the router, the printer, the iPhone, and all other devices/computers. Wait two to three minutes. Power on the router. Wait two to three minutes. Power on the printer. Wait a minute or two. Power on the iPhone. Finally, power on all other devices/computers.

The HP Officejet Pro 6835 e-All-in-One Printer is not listed in About AirPrint - Apple Support as a model supporting the AirPrint technology (an HP OfficeJet Pro 6830 e-All-in-one is). The product specifications (https://support.hp.com/us-en/product/hp-officejet-pro-6830-e-all-in-one-printer-series/5390307/model/7107898/document/c04268294) are vague regarding the 6835 and AirPrint, but clear about the 6830 series. I guess that your model is an AirPrint-enabled printer, but you may want to double-check this (also, check that the printer has the latest firmware).
