You can give formatting and printing commands from a shell within GNU Emacs, just like any other shell command. To create a shell within Emacs, type M-x shell (see Shell in The GNU Emacs Manual). In this shell, you can format and print the document. See Format and Print Hardcopy, for details.
You can switch to and from the shell buffer while
running and do other editing. If you are formatting a long document
on a slow machine, this can be very convenient.
For example, you can use
texi2dvi from an Emacs shell. Here is
one way to use
texi2pdf to format and print Using and
Porting GNU CC from a shell within Emacs:
texi2pdf gcc.texi lpr gcc.pdf
See the next section for more information about formatting and printing in Texinfo mode.
