Installation Permission Issues and Printer Drivers
The most common issues with printer drivers in Windows 7, however, are that they either won’t install or they mysteriously vanish, leaving you with the task of having to reinstall your printer each time you boot up your PC.
This particular issue isn’t as widespread as it once was, however, and is largely due to the lack of administrative privileges on your Windows 7 computer. To get around these problems, you need to install the printer and the drivers by logging into the computer as Administrator. To find out which user account is the Administrator account, go to Start > Control Panel > User Accounts and Family Safety > User Accounts.
If there is no Administrator account, you will need to boot Windows into Safe Mode in order to activate the hidden disabled account. Once you have logged in there, you can begin installing your printer once again, hopefully with better results.
Note that you may need to attempt to reinstall the driver, or search for an updated version. Updated drivers can typically be searched for and downloaded via the support pages of the hardware provider.
