[R] Windows Printing and Line Widths

[McGehee, Robert]

Hi all,
I develop and print from both Windows and Linux, and am seeing some
printing inconsistencies first described about a year and a half ago by
Andy Liaw (see below). Specifically, the line widths on my windows plots
are about 5 times smaller than that on Linux, and my windows printouts
do not match what my screen looks like. However, if I print to a pdf
file first, then I can get accurate Windows reproduction of my screen. I
was thinking of writing a windows.print() wrapper that creates a
temporary pdf file and then prints that. However, I wanted to see if a
better solution now exists to get identical printouts on both Linux and
Windows (since Andy's original post), or any comments on what printers
this does or does not affect.

Thanks,
Robert

What printer driver are you using? 


I've just tried this and it works exactly as one would expect on my HP 
970CXi, as well as cut-and-paste into other applications. It also worked

printing to Acrobat Distiller (although all the lines were thinner there

than on-screen and on the 970CXi, the ratio was still 1:5). 


We've been here before, and had to abandon some optimizations because of
a 
bug in interpreting Windows metafiles in Word.
