HP Support Assistant is printing software to set up your printer, scan, order supplies, check ink levels, and more. After upgrading Windows, the printer information in HP Printer Assistant and Windows is lost. When this happens, use HP Support Assistant to connect your printer as a new printer.
Step 1: Reconnect the printer
Step 2: Click Connect a new printer.
Step 3: Select the connection type when prompted, and then follow the on-screen instructions to set up the printer.
Step 4: Turn off the printer, and then restart your computer.
Step 5: Turn on the printer, and then open HP Support Assistant.
You can access HP Support Assistant from several places depending on your computer (options will vary per computer model):
Click on the HP Support Assistant icon on your desktop
Go to the Start menu, then click on All Programs, then click on HP
Go to the Start menu, then click on Help & Support link on the right
Open HP Advisor and click on the treasure box icon labeled “Get help and Troubleshoot” (bottom right-hand corner)
Hope This Helps,
