It looked like fun, and I found a few good-old wiz-bang items from the '80s, but it didn't see the sort of basic info I needed. But then I found this: http://local.wasp.uwa.edu.au/~pbourke/dataformats/postscript/ Then I figured out that I can insert this somewhere near the top of the file.... newpath 2 312 moveto 12 312 lineto 600 312 moveto 610 312 lineto 0.25 setlinewidth stroke ....and I get the little "fold here" lines I was looking for. The full postscript file looks like this: ----------begin foo.ps on next line------------------ %! %% Example 1 newpath 2 312 moveto 12 312 lineto 600 312 moveto 610 312 lineto 0.25 setlinewidth stroke showpage ----------end foo.ps on previous line---------------- This works assuming US Letter, Portrait (216 x 279 mm). The x-y coordinates place (0, 0) on the lower left and then work in the usual way with 1/72 inches per unit (so y=312 means 4.333 inches up from the bottom of the page -- these envelopes are 4.5" wide, which is a little wider than ordinary business size).
