protocols are FTP, DHCP, BOOTP, RARP, IPP, TCP/IP, and LDAP.
Proxy server
A server that includes a function for accessing remote servers in place of clients on
the local network. Some proxy servers may also include a function for storing the files
retrieved from remote servers. This can increase the efficiency of Web browsing by
enabling clients to retrieve files from the proxy server that have already been retrieved
once, without having to access the remote server again.

provides flexible font capability and high-quality graphics, especially for
high-resolution printing.
Q

When the printer is used in NetWare's queue server mode, all print server functions
are provided by the printer itself, and no other print server hardware or software is
required.
R
RARP
Reverse Address Resolution Protocol. A protocol which associates a network adapter
address (MAC address) with an IP (Internet Protocol) address.
Raster Graphics
Raster graphics represents an image as a pattern of dots, as opposed to vector
graphics, which represents an image as a geometrical formula. Each row of colored
dots in the mosaic of colored dots constitutes one raster graphic. In a printer, a raster
graphic is used as the master image from which a page is printed. The image is then
transferred to paper by printing one raster at a time.
Raw
A print application used with Windows 2000/XP/Server 2003/Vista. It can print at
higher speeds than LPD (Line Printer Daemon).
