Installing drivers for local printing

Serial printing

With serial printing, data is transferred one bit at a time. Although serial printing is usually slower than parallel printing, it is the preferred option when there is a great deal of distance between the printer and computer, or when a parallel interface is not available.

Note: A serial interface card is required and can be purchased separately.

Before printing, establishing communication between the printer and computer is required. To do this:

1Set serial parameters in the printer.

2Install a printer driver on the attached computer.

3Match the serial settings in the COM port.
