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.
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.

used in UNIX and Windows NT environments.
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.
