PCL

Printer Control Language. A protocol originally designed by Hewlett-Packard,
enabling PCs to communicate with printers. PCL has become a standard for laser
and ink jet printers, and is now supported by most printer manufactures.

PDF

Portable Document Format. The page description language used in Adobe Systems'
Acrobat document exchange system, which is restricted neither by device nor
resolution. PDF displays documents in a way that is independent of the original
application software, hardware, and operating system used to create those
documents. A PDF document can contain any combination of text, graphics, and
images.

PDF (Compact)

One of the file formats available in this machine. The text and image portions of an
original are processed separately to achieve a high level of compression without
compromising the quality of the text. The resulting file or data size is smaller than that
achieved by conventional PDF, and is therefore recommended for jobs that are to be
sent over the network.

PDF (OCR)

A file format that performs OCR (Optical Character Recognition) processing on a
scanned document. This process extracts any recognizable text data, and adds it as a
transparent layer to create a PDF with searchable text. You can search the text using
Adobe Reader/Acrobat Reader/Acrobat, or your operating system's search function.

Protocol

A set of rules that govern the transmission of data across a network. Examples of
protocols are FTP, DHCP, BOOTP, RARP, IPP, TCP/IP, and LDAP.

Proxy server

A server that provides a cache of files available on remote servers that are slow or
expensive to access. The term "proxy server" normally refers to a World Wide Web
server that, upon receiving a URL, tries to supply the requested file from its cache. If
the proxy server cannot locate the file in its cache, it obtains the file from the remote
server, and saves a copy in its cache so that the next request can be obtained locally.
