Both help(dev.print) and the "R for windows FAQ"
suggest that dev.print() with no arguments
should work also on Windows

One explanation of the problem is that
getOption("printcmd")
is NULL and frankly I wouldn't know what to put there (Win NT 4, or Win 2k).
Of course all this not a big problem, since at least in RGui, there's the
print button that probably everyone uses.
OTOH, it would be nice if dev.print() was portable and would work on all
platforms (as advertized).
Confirmations, suggestions, opinions ?

Probably dev.print should default to win.printer on Windows, but that would be both a cross-platform- and back-compatibility change.> [Our students have to use Windows, I don't fortunately ...] > > > > dev.print() > Error in PS(file, old$paper, old$family, old$encoding, old$bg, old$fg, : > unable to start device PostScript > In addition: Warning message: > printing via file = "" is not implemented in this version > > > > One explanation of the problem is that > getOption("printcmd") > is NULL and frankly I wouldn't know what to put there (Win NT 4, or Win 2k).See ?postscript on a Windows version of R.> Of course all this not a big problem, since at least in RGui, there's the > print button that probably everyone uses. > OTOH, it would be nice if dev.print() was portable and would work on all > platforms (as advertized).Well, it does if you have a print spooler set, and that applies equally under Unix. -- Brian D.

Most R users probably have installed ghostscript and GhostView, but it is not a standard under Windows. So porting the unix like printing to Windows (via postscript) is tricky. Particularly the windows printer driver system differs from unix and you cannot print a postscript file without ghostscript (or similar software) on a non-postscript (or even worse GDI) printer.
