I haven't confirmed, but the problem looks to be that the "-sOutputFile=-" isn't included in the ghostscript options.

For Unix or Windows the proper pipeline would be,

Just for reference, in the absence of a file name the result should be spooled to the system printer via lpr

Oops, just found this has been reported and commented on already as #38166. I have provided extra detail here that wasn't in that report.

Originally reported at http://bugs.debian.org/710423

The print command fails to print to a printer when no filename is specified if various -d options are passed to print. At the very least print should either error on an invalid combination or just ignore and print as if no -d option had been given. I can't say what Matlab does.

Example 1, "print -deps" with gnuplot:

Example 2, "print -dpng" with gnuplot:

... and the following is actually sent to the printer and printed as plain text:

Example 3, "print -deps" with fltk:

No error, but the contents of the EPS are dumped as text to the same terminal that Octave is running in.

Example 4, "print -dpng" with fltk:

Also no error message, but what appears to be the byte content of a PNG is sent as text to the printer and printed, one or two lines of nonsense per page.

I started looking at what _print_parse_opts_ does with these various combinations of options. I assume this can be fixed in there with some logic about whether the output filename was specified or not.
