I need a CD-KEY to down load the program to run my HP ENVY photo 7855 PRINTER.

I had removed this printer and want to reinstall it. And it says I need a CD-Key. The printer is 4 years old and I have not been able to find the key in my information from when I purchased it.

Hello,

Welcome to the Microsoft Windows Community.

Good evening. Printers do not require an activation serial number; simply connect the cables and install the driver,

Select and download the universal driver.:

You do not need a CD key to reinstall an HP ENVY Photo 7855; download its Windows 10 software directly from HP’s official support page.

Reinstall the HP software

Turn on the printer.
If using Wi-Fi, connect the computer and printer to the same network. If using USB, keep the cable available and connect it when the installer requests it.
Open HP’s driver page for the exact printer model: ^1^
Select Windows 10 if HP asks for the operating system.
Download the recommended setup software or driver.
Open the downloaded file—normally found in the Downloads folder—and follow the installation prompts.
Choose Wireless or USB when asked how the printer connects.

HP also provides a dedicated setup page for this model, including its supported setup choices.^2^

Do not purchase or enter a “CD key.” If a website or installer demands one, close it and use the official HP page above.

If the HP installer cannot find the printer

In Windows 10:

Select Start → Settings → Devices → Printers & scanners.
Select Add a printer or scanner.
Wait for HP ENVY Photo 7855 to appear.
Select it, then choose Add device.

For a USB connection, plug the printer directly into the computer and turn it on before using Add a printer or scanner. Windows should attempt to detect and install it.^3^

Last resort: load the driver through Windows Update

If neither HP’s installer nor normal printer detection works:

Go to Start → Settings → Devices → Printers & scanners.
Under Related settings, select Printer server properties.
Open the Drivers tab and select Add.
Select your computer’s processor architecture.
On Printer Driver Selection, select Windows Update and wait for the printer list to refresh.
Choose HP as the manufacturer and select the matching ENVY Photo model.
Complete the wizard, then return to Printers & scanners and add the printer.

Microsoft identifies this legacy wizard as a last-resort method that may help with older printers.^4^
