A+ Second Edition Genetic Computer School Drivers Windows 9x, 2000, XP  are Plug and Play compliant  most device drivers are installed automatically If a device is not detected, Use the "Add New Hardware" control panel. This will launch a wizard that will build a database of drivers to choose from. If your device is not on the list, you can choose the "Have Disk" option and install a driver provided by the manufacturer. Update Drivers Drivers can be updated from the Device Manager by selecting the device, clicking the properties button, clicking the driver tab and then the update driver button. This will launch the "Update Device Driver Wizard".

A+ Second Edition Genetic Computer School Drivers Windows NT is not PnP compatible, which means that drivers have to be installed using an installation CD from the manufacturer or using the specific control panel for the type of device.

A+ Second Edition Genetic Computer School Printer Concepts A machine that could capture information and output onto a piece of paper. It connects to the computer via a serial or parallel port. Sometimes printers could also be part of the network; (use a NIC to interface with the network) Most of the printers nowadays use a parallel interface. The parallel cable usually has a DB 25 male connector on one end and a 36 pin Centronics connector on the other end.

A+ Second Edition Genetic Computer School The output of a printer The output of a printer is measured in dots per inch (DPI). This resolution means how many dots a printer could print per inch. The output image of a printer is most commonly put onto paper. The size that is used most of the time tends to be 8.5x11 or legal size 8.5x14 inches. Feeding a form (form feed) involves pulling a piece of paper into the printer and moving it back out of the printer. If it is only a single piece of paper that is moved through the printer this is known as sheet fed. If the pieces of paper are connected and move through the printer continuously this is known as continuous feed.
