Many thanks to Tom Oelke <tpo9617@rit.edu> for providing this question, answer & snippet of code:
The following section of code gets the postscript code for the section of canvas that's top-left corner is at $min_x, $min_y, and has a width and height equivalent to the displayed region. This ps code is then piped out to lpr to be printed.
my $ps = $canvas->postscript( '-x' => $min_x, '-y' => $min_y, -width => $canv->Width, -height => $canv->Height); open (PS, "| lpr"); # customize with -Pname e.g. print PS $ps; close (PS);Whereas you would use something like:
open (PS, ">file.ps"); # to output to a file print PS $ps; close (PS);
