LATEX documents with included plt figures can be processed, previewed, and printed without special treatment. Typically, your LATEX source file has a name of the form myfile.tex, and you use latex to produce a .dvi file:
Once you have a .dvi file, you can view it with xdvi, as in:
xdvi myfileRecent versions of xdvi include a View PS button that toggles display of included PostScript figures. Note that some older versions of xdvi are not able to display rotated or anisotropically scaled plots.
Use dvips to create a printable PostScript file from the .dvi file:
The PostScript file generated by dvips can be previewed using gv (under MS-Windows, GSView) or printed directly using lpr:
gv myfile.ps lpr myfile.ps
