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.
