ps files don't necessarily use bitmap fonts. However, in most free. TeX distributions, dvips uses Type 3 fonts by default. This can be changed by editing the config.ps file.

The problem with the vast majority of Type 3 fonts is that they target a particular device resolution and look bad at other resolutions. A typical Type 1 font is designed to look good at any resolution.

I use Type 1 fonts whenever possible, for both .ps and .pdf files.

The UK TeX FAQ mentions command-line options needed to use Type 1 fonts with dvips:

http://www.tex.ac.uk/cgi-bin/texfaq2html?label=dvips-pdf

If you want this to be permanent, I think you need to set type1_default=true in your updmap script (texmf/dvips/config/updmap on my teTeX system) and then execute the script to produce various map files.

The above assumes you already have CM Type 1 fonts, which most distributions these days do.

You can generate postscript from latex that doesn't contain font descriptions, just font names. Since few tools and no printers come with the computer modern fonts installed, this is strongly discouraged if you are using Computer Modern fonts. If you change the font selection so that you are using fonts such as Times Roman and Helvetica, this is reasonable.

From http://www.math.hawaii.edu/~ralph/MathOnWeb/TeXPDF.html

By default, TeX uses bitmapped, `PK' fonts which do not render well in environments where the resolution is not fixed, such as Adobe Acrobat. Therefore, LaTeX authors should use a standard font such as Times Roman in place of TeX's PK. Mathematical formulas and symbols remain in a bitmapped format, but the majority of the text will be in a scalable font. LaTeX authors may direct TeX to use Times Roman fonts by including the `times.sty' style file. For example, the first line might appears as: is that the characters are slightly smaller, so you can fit more text per page.

From http://www.wfu.edu/Academic-departments/Economics/ftp/times.htm

The times.sty will not put mathematics into Times: it will still be in Computer Modern. For math, it is hard to get results as good as those obtained with TeX's default fonts. To get good results you will probably have to buy a commercial math font package such as Mathtime from Y&Y. What times.sty does offer you is (a) Times instead of Computer Modern for roman, italic and bold, (b) Helvetica instead of TeX's sans serif font and (c) Courier instead of TeX's typewriter font.

From http://www.ieee-infocom.org/2001/latex.html

Use of Times fonts is highly recommended for consistency and readability both on screen and in print.

With LaTeX2e use the command

\usepackage{times}

and with LaTeX 2.09 use the command

\documentstyle[times]{...}

You will need the following packages: times.sty, rawfonts.sty.
