When I unplug my 2610 printer to move it then plug

First disconnect the printers USB cable from the PC. Go to the control panel and open add or remove programs. Find the installed software for your 2610 printer and select to uninstall the software. When completed restart the PC. Install the latest software for your printer from HP.com and during the installation it should prompt you when its time to connect the printer. When prompted, connect the USB cable from the printer to the PC and power up the printer. You should see a message indicating that your computer has found new hardware and is installing the necessary software to complete the installation. Call HP support if these steps don't resolve the issue.
