Printer / File exclusive setting:
Allows the user to choose whether the output is written to a file or
piped to a printer. The default is to print to a file. The read-write text field
immediately to the right of the Printer option specifies the printer to which the
plot will be sent. The default printer name is specified by the
environmental variable LPDEST if set, by the environmental variable PRINTER if LPDEST is not set, or
the default printer name, ``lp''. The read-write text field immediately to the right of the
File radiobutton specifies the filename of the PostScript file to which data is saved. The
default is the file ``test.ps''.
A common experience is to attempt to print a PostScript file which is too big to fit entirely
within a printer's buffer.
In this case, we recommend attempting to print the file with the
UNIX command lpr -s filename. We remark in any case that piping data directly to a printer
is somewhat riskier than creating a PostScript file and then sending that file to the printer,
chiefly because if the pipe fails for any reason, then the image may be lost.
