Output format

By default, lwcat sends its output directly to the default printer via lpr. These options may be used to modify this behavior:

Send the output to the printer, but don't eject the page (use this option if you wish to overlay the output with additional material to be produced by another program).
Write PostScript to the standard output (not to the printer).
Write PostScript to a temporary file and view it with gv (ghostscript).
Same as -psv.
Write EPSF (encapsulated PostScript format) to the standard output. Note that this is only a close approximation to EPSF; it is acceptable to LaTeX's epsfig package, at least.
Write PDF (portable document format) to the standard output.
Write PNG (portable network graphics) format to the standard output.
