The HP Envy Photo 7855 is a photo inkjet (print, scan, copy) with a photo tray and memory-card slot. Use HP Smart or the Envy 7855 software from support.hp.com. A LaserJet Universal driver will not work.
WiFi with HP Smart
- 2.4 GHz only during setup. Split dual-band SSIDs if needed
- Put the printer in setup mode (wireless blink), then open HP Smart on the same network
- If Smart never finds it: panel wireless wizard, then add by IP — cannot find printer
- Passphrase errors: invalid WPA passphrase
General wireless: HP WiFi not connecting.
USB when wireless will not hold
Data cable, not charge-only. Install HP Smart anyway so scan from the glass still works.
Photo tray vs main tray
Photo paper in the photo tray, plain paper in the main tray, and match that in the driver. Wrong tray looks like a “driver failure.” Ink: check the label in the cartridge door (often HP 64 / 64XL in North America).
First-run maintenance
First ink charge can sit on maintenance in progress for several minutes. Do not unplug. Blank output after that: blank pages.
