Basic concepts of TCP/IP printing
In Windows NT, printing via TCP/IP is accomplished using the LPR (Line Printer
Request) protocol. Because LPR was developed for UNIX systems, comparing
Windows NT and UNIX implementations may be helpful.
The LPR protocol is a host-to-host protocol, rather than a host-to-printer protocol.
When printing via LPR, the computer sending the print job assumes that it is
sending the job to another computer, or print server, which sends the job to the
printer. In UNIX terminology, the print server is called a remote host. The print
server can have several printers connected to it. The way to differentiate between
different printers when spooling to the print server is to print to a specific remote
queue.
The following table summarizes these concepts of TCP/IP printing and the
terminology used in UNIX and Windows NT environments.
Concept Description
Print server An IP address or a DNS name
that is mapped to this address.
This is how your computer knows
where to send the print job.
Print queue For Tektronix printers, this is PS
(PostScript) or AUTO
(AutoSelect).
Your Tektronix printer emulates a print server. Tektronix printers are accessed by
giving an NT host a remote host name that will point to the printer. This is true only
if the print job is spooled directly to the printer via its internal network interface, and
not through an external third-party print server. If the print job is spooled through
an external third-party print server, the remote host name is the TCP/IP address of
the print server and the remote queue name is the name of the queue for that print
server.
