To access the printers in the EDLAB use:
% lpr [options ..] [filespec..]
If no file names appear then the standard input is assumed. Normally
the default printer is used, or the value of the environment variable
PRINTER is used. It is possible to set the value of PRINTER, as one
wishes with the setenv command (section on User Environment).
However, the -P option may be used to force output
to a specific printer. Other options are listed in the man page for lpr.
% lpr -Pelprt2 myfile.txt
