[Octave-bug-tracker] [bug #38166] crash when printing with no output file (i.e. spooling via lpr)

[Ben Abbott]

Update of bug #38166 (project octave):

                 Summary: crash on incorrect print command => crash when
printing with no output file (i.e. spooling via lpr)

    _______________________________________________________

Follow-up Comment #5:

In the absence of a file name, the print command produces a temporary file
which is spooled to the system a printer via lpr.  Using the "-debug" will
provide information for debugging what goes wrong (the print command works for
me on MacOSX)

For Gnuplot ...


print -dpsc -debug
