How do I delete run dll message that continues to appear after uninstalling my hp 7510 printer?

[AmarilloJer]

The printer has been uninstalled and a new Epson printer replaced it. The Run DLL message continues to appear every time the computer is turned on.

@AmarilloJer Here's all you need to do:

Press "Windows key" + "r" to get the "Run" window.

Type "services.msc" to get Services - Go to "Print spooler" - Right-click and "Stop" the service.

Now again open "Run" - Type "spool" and ok - Go to PRINTERS folder - delete everything in that folder.

Go to services again - Start the print spooler.

Now check for issue resolution.

If the issue persists, unplug the USB cable from the printer (if present). 

Go to Control panel - Programs and feature - Select all the HP 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 the Hewlett Packard folder, remove any printer related folders & files.

Restart your computer.

Then, use this link to access the HP website, find the drivers compatible with your windows and install it: www.hp.com/drivers
