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.        

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.

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).
