OK - here's the deal. I have 3000 pairs of files to print. Each of these files takes up one normal logical page. Our printer (PrintStation 20) and Ultrix lpr command allow me to automagically print two pages on the same side of a physical sheet. Basically, each logical page is rotated 90 deg. and scaled down. With (say) two logical pages of text, (in two separate files in this case) this produces one physical sheet. When the sheet is held long axis up, the text of page one goes top to bottom on the left side of the page, and page two goes on the right, so the page looks like :__________________ | text | text | | page | page | | one | two | ------------------- Now, I have two files that are normally printed in landscape mode. I want them to come out like : ----------- | page one| | | | | | | ----------- | page two| | | | | | | ----------- on one physical sheet of paper. They do come out that way, with one problem. Page one is upside-down, so that the tops of both logical pages appear in the *center* of the physical page. The files : one is plain ascii text; I have been using enscript -r to make it into a landscape-oriented PS file. The other file is an IDL-generated graph which is already in PS form. My problem is definitely caused by differ- ences between the two files; if I print two IDL graphs on the same page they come out with the proper orientation. Does anyone have any suggestions as to how I can get one of these files (doesn't matter which) rotated so it will come out properly? -Robert.-

There is a line in there that looks like this: /Landscape{90 rotate 0 -15840 translate}def You should change it to look like this: /Landscape{-90 rotate -15840 -3600 translate}def Note: enscript uses a strange coordinate system and in fact places the origin off the page when in Landscape mode, but at least experimentally the above code seems to do the trick. You might need to hack the translation components if it isn't working for you. As a reference, the number -15840 is exactly 792 points (the long edge of an 8.5"x11" page) multiplied by the enscript scale factor of .05. The value -3600 is (792-612) / .05 for obscure reasons (the aforementioned off-page condition). For "normal" PostScript code on a letter-sized page, you would see either 90 rotate 0 -612 translate or -90 rotate -792 0 translate to get you into Landscape mode in either orientation.
