Computer will not recognize my printers
 

Computer will not recognize my printers. It says they are unplugged and
they are plugged in.

1) printers...as in more than one ???? if they are plugged in through USB ports then it is a good possibility that since all went out at same time that the USB hub or controller went bad or lost the drivers or you have a bad connecting cable(s)

a) if you are using a USB hub to connect the printers...try using a USB port directly on your computer to see if they will work now.

if not...

b) start > control panel > system > hardware tab > device manager and check to see if you have a !or ? next to the USB controller or possibly an unknownpiece of hardware....you will need to reinstall the usb drivers

c) try a different connecting cable

*****if you are using a paralell port for your connection then the proceedure for trouble shooting it would be the same as ....b...above.

***** networking print servers would have to be checked out by a network adminastrator to asure proper connectivity.

***** If the printer died then it will also show the same warning.

as a last resort uninstall the printers and using the manufacturer's installation proceedures....re-install the printer from scratch.
Use the uninstall driver in device manager to remove the old driver(s) then unplug the printer and use the add/remove application in control panel to uninstall all the old printer files.
