Follow-up Comment #1:

Confirmed.  A very simple example to reproduce is


clf;
ht = text (0.5, 0.5, "This is a backslash (\\).");
print -dpsc2 bslash.ps


This is not specific to Windows; I reproduced it on Linux using the code
above.  The "interpreter" property is also a red herring as either "none" or
"tex" have the same issue.  I believe this is going to be a problem with the
gl2ps library.  We may be forced in Octave to work around it by filtering the
output of gl2ps before we pass it to Ghostscript.

As a workaround for now you can go through svg and pdf formats which do work. 
On a Linux machine which has the pdf2ps converter this sequence works


print -svgconvert bslash.pdf
system ("pdf2ps bslash.pdf")
