232 Chapter 10. PostScript and PDF
Its two most significant features are the inclusion of graphics as encapsulated
PostScript images, as described in Chapter 6, and the capability of
making use of PostScript fonts in place of the Computer Modern ones (Section
G.5). There are also enhanced drawing capabilities, as demonstrated
in Sections 13.2.2 and 13.3.2.
10.1.1 The dvips driver
The dvips driver program operates on the DVI result from T E X, with or
without L AT E X, to generate PostScript output, which may be written to a
file or sent directly to a printer. One either clicks the appropriate icon in
the editor shell, or issues the command from a command line prompt:
dvips myfile
to process myfile.dvi and generate myfile.ps. (The L AT E X source text
was of course in myfile.tex.) The PostScript file may be viewed with
a PostScript viewer like GhostView or sent to a PostScript printer, or
included in an email.
There are many options that may be included in the command line,
appearing between dvips and the file name. For example, to output five
pages only starting at the 10th, sending them to a file named p5-15.ps,
give
dvips -p 10 -n 5 -o p5-15 myfile
You may also specify the first (-p) and last (-l) page numbers, whether
only odd (-A) or even (-B) pages are to be printed, or in reverse order (-r).
The page numbers with -p and -l refer to the actual page numbers in
the document, or rather to its first occurrence. Hence -p 8 might start
with page viii rather than page 8. Specifying -p =8 will start with the 8th
page, regardless of its actual number. The list of options can be printed
to the monitor with dvips --help.
One useful option is t landscape to rotate the output into landscape
mode, which should be done if the document has been processed with
the landscape option in \documentclass. However, dvips has another
way of accomplishing this: add the driver-specific command
\special{landscape}
in the source text itself and dvips will automatically print in landscape
mode.
The output is written to a file with the same root name as the input,
but with extension .ps, unless the option -o filename is given. To send
the output directly to a printer, specify that printer as the output ‘file’, as
-o \lpt1. Beware, if that printer is not a PostScript printer, it will simply
output the PostScript code directly as text, something that normally uses
a considerable amount of paper.
