Net Mask
Certain bits of the Host ID of an Internet address can be used to describe sub-networks. The network
mask assigns the separation into (sub) Network ID and Host ID.
Example:
Without using sub-networks, the NetMask in the example above would be 255.255.255.0. If one bit of
the Host ID is used to define two sub-networks, the Net Mask has to be set to the value
255.255.255.128.
Now the Host IDs will be restricted to the range from 1 to 127. Following Internet addresses would
then be valid:
192.0.0.1 - 192.0.0.127 in the first subnet,
192.0.0.129 - 192.0.0.254 in the second subnet.
Default Gateway
The is the gateway’s Internet address to which the print server sends IP packets destined for other
networks.
Printer Name
Your print spooler uses this name to address the printer after installation. This name can be freely
chosen, but must be unique in your network. It may be useful if the name describes the connected
printer. You can assign several logical printers to a physical printer which use different printer
emulation.
Example:
You installed a printer. A good name may be printer1 or printer1_ps for the same physical printer in
postscript emulation, or printer1_hp for the emulation of a HP LaserJet.
Print Spooler
The print server supports the print spoolers
lpsched
(System V UNIX),
lpd
(BSD UNIX) and
qdaemon
(AIX). Please refer to your systems manual or ask your system administrator which of the
UNIX variations is installed on your workstation, and which print spooler is selected. If you can see
the
/usr/lib/lpsched
file installed on your system you may have a System V UNIX or BSD,
and UNIX if the files
/usr/lib/lpd
and
/etc/printcap
are installed.
Network Service BOOTP and RARP
Please find out now if any, or which of these network services are available in your system. If the files
/etc/bootpd
(ULTRIX:
/usr/etc/bootpd
) and
/etc/bootptab
are present, then BOOTP
is implemented. If the files
/usr/etc/rarpd
and
/etc/rarpd.cf
or
/etc/ethers
are
installed, then the RARP service is available. Depending on the UNIX implementation of your system
the files may have different pathnames.
Using the 8 TCP ports
Besides the access to the printer ports of the print server gained via FTP, the print server provides a
TCP socket for each printer port. The socket’s port number may be assigned parameters (refer to
logical printer). This option is primarily aimed at hosts supporting a direct TCP/IP connection of
network printers.
