(which can be reduced to simply
by taking default shortcuts) will create the necessary file Times-Roman.tfm, which can then be moved to the directory where TeX normally looks for font metric information. The PostScript conversion program dvips will also treat Times-Roman as a resident PostScript font if you include the line
in the file psfonts.map.
PostScript fonts have a different encoding scheme from that of plain TeX. Although both schemes are based on ASCII, special characters such as ligatures and accents are handled quite differently. Therefore we obtain best results by using a "virtual font" interface, which makes TeX act as if the PostScript font had a standard TeX encoding. Such a virtual font can be obtained, for example, by the command
or, more fully, by:
This produces two outputs, namely the "virtual property list" file times.vpl and the TeX font metric file Times-Roman.tfm. The latter file describes an "actual font" on which the virtual font is based.
To use the font in TeX, you should first run
then install the file times.vf in the directory for virtual fonts and install times.tfm in the directory for TeX font metrics. (You can also make more complex virtual fonts by editing times.vpl first.) Once this has been done, you're all set. You can use code like this in TeX henceforth:
\font\myfont=times at 10pt
\myfont
Hello, I am being typeset in Times-Roman.
Note that there are two fonts, one actual (`Times-Roman', which is analogous to a raw piece of hardware) and one virtual (`times', which has typesetting knowhow added). You could also say `\font\TR=Times-Roman at 10pt' and typeset directly with that, but then you would have no ligatures or kerning, and you would have to use Adobe character positions for special letters like \ae. The virtual font called times not only has ligatures and kerning, and most of the standard accent conventions of TeX, it also has a few additional features not present in the Computer Modern fonts. For example, it includes all the Adobe characters (such as the Polish ogonek and the French guillemots). It also allows you to type 58 accented letters from `Aacute' to `zcaron' as if they were ligatures --- namely as `acute' followed by `A', etc., where you can get `acute' (\char 19) by defining a suitable control sequence. (The 58 constructed characters are found in the AFM file, and constructed as specified by Adobe; you may wish to adjust the spacing and/or add additional accent combinations by editing the VPL file.) The only things you lose from ordinary TeX text fonts are the dotless j (which can be hacked into the VPL file with literal PostScript specials if you have the patience) and uppercase Greek letters (which just don't exist unless you buy them separately).
These fonts can be scaled to any size. Go wild! Note, however, that using PostScript fonts does use up the printer's virtual memory and it does take time. You may find downloading the Computer Modern fonts to be faster than using the built-in PostScript fonts!
which create timessl.vpl and Times-Slanted.tfm. To use this, proceed as above but put the line
Times-Slanted "/Times-Roman .167 SlantFont"
into psfonts.map. Then Times-Slanted will act as if it were a resident font, although it is actually constructed from Times-Roman by PostScript hackery. (It's an oblique version of Times-Roman, obtained by slanting everything 1/6 to the right.) Similarly, you can get an extended font by
and by recording the pseudo-resident font
Times-Extended "/Times-Roman 1.2 ExtendFont"
