If you are using LaTeX to typeset your solutions, you can get Postscript files using latex followed by dvips, and PDF files by using pdflatex. For other conversions, read on. Whatever method you use, please read over yr files before submission to ensure the conversion process has not introduced any errors.

• Converting Files to PDF

  Primo PDF seems to be an excellent, easy, and free solution for making documents into PDF files. Once installed, you can use it as you would any printer. (See the PrimoPDF manual for details.) IMPORTANT: When printing, a dialog will pop up asking you where to save the file. At the top of this dialog it asks you to choose a mode: choose Print mode rather than Screen mode for better output.

  We are told that PDFCreator (download) is another good way to convert files to PDF, with many options, but we have not tried this yet. Let us know if you like it.

  We tried the web-based Neevia Document Converter recently to convert Word to PDF; it is non-intrusive and not too slow (80 page text-only Word file to PDF in 30 seconds). Another option is gobcl.com.

• Converting files to Postscript (Windows)

  If you must convert files to PS under Windows, try to print the file, but click the "Print to File" option. (It will then ask you for a file name.) Assuming that you were printing to a Postscript printer (and you most probably will be), this will fool Windows into generating a postscript file. IMPORTANT: Some of these postscript files can be huge, so use this option only if there is no other alternative.

  If your machine does not have a postscript printer as the default, you can install one. Details can be found on pages here, or here (local instructions). Then you can select this installed postscript printer to print to (except that you will also check "Print to File"), and the output will be in postscript.

• Adobe PDF to Postscript (PS)

  On *nix, the program is pdf2ps. On Windows machines, follow instructions for converting Word to PS.

• Multiple pages of ps file on one physical page:

  I have seen a tool called mpage, but the andrew machines do not have it. The util here is psnup, used like this: psnup -nRxC -p outputfile filename, for example: psnup -n3x2 -p rec1_6up.ps recitation01.ps.
