The following documentation was found:
pdftops - Portable Document Format (PDF) to PostScript converter (version 0.6)
pdftops [options] [PDF-file [PS-file]]
Pdftops converts Portable Document Format (PDF) files to PostScript so they can be printed. Pdftops reads the PDF file, PDF-file, and writes a PostScript file, PS-file. If PS-file is not specified, pdftops converts file.pdf to file.ps. If PS-file is '-', the PostScript is sent to stdout. The generated PostScript is Level 2. This means it will not work on old printers which only support Level 1 PostScript.
-fnumber Specifies the first page to print. -lnumber Specifies the last page to print. -h Print usage information. (-help is equivalent.)
This is a beta release of pdftops, and there are still a bunch of PDF features which I have yet to implement. At this point, the biggest problem is that embedded fonts are not handled properly.
