hello, it wanted to know as printing a graphics on a screen, without to have save in a file, already use dev.print and give me an error in PS , unable to start device postscript and a warning printing via file =" " not implemented.Thanks Ruben
Please read ?dev.print completely, which tells you (among other things):
"The default for dev.print is to produce and print a postscript copy. This will not work unless options("printcmd") is set suitably and you have a PostScript printer: see postscript for how to set this up. Windows users may prefer to use dev.print(win.print)."
