Paper Path

The path the paper follows in its journey through the printer; it begins at the paper cassette or tray pickup point and ends at the output tray.

Parallel Interface

A data transmission technique that sends each bit simultaneously over separate lines. (For this reason it is generally faster than a serial interface.) It is normally used to send 1 byte (8 bits) at a time between computers and printers. Your printer has a Centronics parallel/IEEE 1284 bidirectional parallel interface port. See also serial interface.

Parity, Parity Check

The addition of overhead bits to ensure that the total number of 1s in a grouping of bits is either always even (for even parity) or always odd (for odd parity). This permits detection of single errors. It may be applied to characters, transmission blocks, or any convenient bit grouping.

PCL

See HP PCL.

PCMCIA

An acronym for Personal Computer Memory Card International Associa- tion, which sets industry guidelines for a standard 16-bit expansion socket that accepts credit-card size memory cards (such as fonts). Type I card slots accept 3.3 mm (.13") thick cards while Type II card slots accept 5 mm (.20") cards.

Peripheral Device

A hardware device connected to a computer (such as a printer) or to a printer (such as an external hard disk).

Permanent Soft Fonts

Permanent soft fonts are soft fonts downloaded into the printer's memory that remain resident there, even if the printer is reset, until the printer is turned off or the fonts are deleted by an application. See also download.

Physical Memory

The amount of RAM installed in the printer.
