Enscript can only deal with plain text file. To save space and paper, you can change any postscript file to print two pages to one page. This can be done by the following command:
psnup -2 original.ps new.psIn LATEX, you can set things up directly:
\documentclass[psfig]{seminar} \twoupshould print the slides two to a page. There are sets of formatting macros (.sty files) for use with TEX and LATEX that make things simpler, and some that adhere to university guidelines for text (ie, thesis) preparation are available.
