Actually the problem was the other way around. I got good results sending
the PNG to lpr but bad results sending the PS file to lpr.

Interestingly, William Kyngesbury tried the same PS file on a different
printer and it looked fine. So it may be a function my Epson inkjet here at
home. If so, this will make it difficult for me to test changes to the print
routines in TclTk.
