Hello. This is a problem I've had since I purchased a new laptop earlier this year. The new laptop is HP running Windows 7. The printer is a multi-function Brother MFC-8500 printer/fax/copier/etc. The printer is at least 12 years old.
Almost every time I want to print, I have to reinstall the printer since it is always offline. When I do reinstall it I usually find one or two copies of it in Devices and Printers. In other words, the MFC-8500 appears and there is also MFC-8500 (1) and MFC-8500 (2). None of them are online so I have to delete all three and reinstall. In reality this does not take that long but it is annoying.
Is the printer just too old? There is a driver in the Windows 7 software.
