Downloading and viewing PostScript documents
About PostScript
PostScript (a registered trademark of Adobe
Systems Incorporated) is a page description language used by
many
printers. Because it is provides a consistent way to encode
special
characters and graphics, it is also being used increasingly on the
web as a
way of storing mathematics documents.
PostScript documents on my web pages
A lot of the pages on the web sites for my courses
are stored in both HTML and PostScript format.
The HTML pages are somewhat smaller, so they
download quickly, and they produce better-looking screen images.
However, they are very slow to print and the printed output is of
poor quality. They are also stored as PostScript files
so
that you can print them exactly as they were intended to be seen.
Since most web browsers cannot display PostScript files, you need
to
have either a PostScript printer or an external program that can
handle PostScript files.
Viewing PostScript documents on C & C computers
If you are viewing this page on one of the Computing and
Communications computers at UW, your computer should already be set
up
to display PostScript documents on the screen. Just click on a
hypertext link that points to a PostScript document, (included
at the end of each HTML file of the solutions, tests or whatever)
and the PostScript document should pop up in a separate window. If
this
doesn't work for you (for example, if you get an error message or a
dialog box asking you if you want to save the file to local disk),
ask
one of the C & C consultants for help. If there are no consultants
around, you can send e-mail to help@cac.washington.edu.
Once you are looking at the PostScript viewer's window, there
should be a
menu option (usually on the "File" menu) that will allow you to
print the
document.
If you don't have a PostScript viewer...
If you are using a computer other than those provided by C & C,
such as
your home computer, there may not be a PostScript viewer available.
In
that case, if you have a PostScript printer (for example, any
Apple Laserwriter), you can download the file to your disk and then
simply
print it as is. Consult your browser's documentation or help
screen for
information on how to download files to local disk.
Obtaining a PostScript viewer
If you're ambitious and have lots of disk space available, you can
download
a PostScript viewer and install it on your own system. There are
free
viewers available for Macintosh, Windows, OS/2, and X-Windows. In
each
case, you need two separate programs: Ghostscript (a PostScript
interpreter), and a screen viewer to go with it. Here is where to
get
information and download the programs:
- Aladdin
Ghostscript, a PostScript interpreter for Mac, Windows, OS/2,
Unix.
- GNU
Ghostscript, another version for Unix only.
- GSView, a
screen viewer
for Windows, DOS, or OS/2 PC's.
- Ghostview,
a screen viewer for Unix/X-Windows workstations.
- Mac
GS
Viewer, a screen viewer for Macintosh.
- Ghostscript,
Ghostview & GSview home page, with general information about
PostScript
interpreters.
