Cannot get printer to print

[ljorange2]

I've installed, registered, have printer email address and claim code, printer is on, no edits or blinking lights and wireless light is on. When I try to print I get alert 'printer validation failed".  I uninstalled printer and re-installed.  No luck.

Hello, @ljorange2 – Greetings!

Welcome back to the HP Support Forums, I'd be happy to help you with your printer issue 🙂

Going through your post, I understand that you are having issues while printing on Envy 7645. It looks like an issue with the printer drivers installed on your Windows PC. Do not worry, I’m here to help you fix the same 🙂

Let’s first try to fix this issue using HP Print and Scan Doctor (PSDR). PSDR is an automated tool which can diagnose and resolve printing and scanning problems. Please go to http://hp.care/2bZ9w2q to download and run HP PSDR. Once you open the program, select your printer and click on “Fix Printing” to automatically diagnose and fix the issue.

If the issue persists, then perform a clean install to try and fix the issue;

• First, unplug the USB cable from the printer if present.
• Go to Control panel – Programs and feature – Select all the HP Envy printer entries and uninstall them.
• Now go to Control panel – Devices and printer – Select all the printer entries and remove the device.
• Press the "windows key" + "r" to get the "Run" window open - Type "printui.exe /s" (There is a space between .exe & /) and press enter.
• Under print server properties, go to drivers - remove any entry there as well.
• Again, go to the Run window, type – “c:/programdata” – Go to Hewlett Packard folder, remove any printer related folders & files.
• Restart your computer.
• Now click http://ftp.hp.com/pub/softlib/software13/printers/EN7640/EN7640__Basicx64_1107.exe to install the software.
• Connect the USB cable if prompted and follow the on-screen instructions to complete the installation.

Those steps should do the trick, let me know the outcome!

Good luck 🙂
