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

.
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

Physical Memory
The amount of RAM installed in the printer.
