Note: Options must be specified in lowercase characters; multiple options can be
specified separated by commas.
There must be an entry in the options field; use the word “None” if no options are desired. There must also
be an entry in the server_hosts file for each ETS print queue you wish to use. You may have multiple UNIX
print queues using the same ETS print queue (for example, when you want to use different sets of options)
but a UNIX print queue cannot use multiple ETS queues.
Use the lpstat -t command for lp spooling systems or the lpc status command for lpr spooling systems to
make sure the printer was created correctly. For example, if we created printer hp4 on our lp spooling
system, entering the lpstat -t command might display the following information:
Figure 7-15: lpstat -t Information
For an LPR type spooling system, the corresponding output would look like this:

7.3.5 Setting up the RTEL Named Pipe Daemon
The basic concept behind the RTELPD daemon is to allow a UNIX system to use its own output filter
programs that provide special purpose post-processing and then write the data into a named pipe device.
The RTELPD daemon will read the data from the pipe and send it out over the network to a terminal or print
server port.
Note: The output filter in this case is either provided by the host system or is custom
software. It is not provided as part of the RTEL software package.
Formfeed Formfeeds (ASCII 0xC, Ctrl-L) are appended to the end of the
job. This option should not be used with the PostScript or Binary
options.
None No options are enabled
Postscript A Ctrl-D (ASCII 4) is used to terminate a print job, rather than the
standard formfeed (ASCII 12).
