This program will filter tektronix style plots to postscript output, letting you use your laserprinter instead of the thermal printer that tektronix has been selling since the dark ages. I haven't been able to really test the defocussed Z axis stuff (no plot programs that we have use it). I have put as much as possible into the prolog file so a user can fairly easily change the defaults I like to those he or she likes. The tough part about figuring out how this works is understanding the Tek addressing schemes. Other than that, it is pretty simple. There is one `undocumented' flag: -d, which enables more verbose messages when an otherwise ignored character is encountered. Usually, these are padding characters (4010s are very slow by modern standards). BE SURE TO EDIT THE PROGRAM (tek2ps.c, find def_pro) AND DOCUMENTATION (tek2ps.doc, about the tenth line) to put the correct location for the default prolog file in! Any corrections or additions?
