The libraries, used by the Epson FX-80, have a special trait:
They are not quadratic in their resolution. The smallest
fontlibrary of the draft resolution has 120dpi horizontally
and 72dpi vertically.
In the Letter Quality resolution, the proportions are 240dpi
horizontally as opposed to 216dpi vertically.

Flib's for the Epson FX-80-driver
Because of this asymmetry and the fact, that the
draft resolution is sufficient for the screen resolution,
the problem rears its head, that fontlibraries exist, which,
although they have the same name, have an entirely different
structure. These are e.g. for a screen resolution of 100dpi
for example the libraries PK0120, PK0131, PK0144, PK0158,
PK0173, PK0207 and PK0249. For a different resolution used
for the previewer, other overlaps occur. This problem can be
solved quickly and efficiently with the fontdefinition file,
as there is one for the previewer and the printer driver each.
You copy the libraries which exist twice to some directory and
change the configuration file accordingly. As libraries, which
are defined there, are first searched on the given spot, the
previewer libraries are not used in the <#104#>TeX:fontlib<#104#> directory.
You can also solve this problem, in that you rename all fonts and
include the horizontal and vertical resolution in the font- library-
name. For that purpose the modifiers ``h'' and ``v'' exist,
as well as ``x'' and ``y''. Thus you can define the format strings
in the following manner:

With this the font <#106#>cmr10<#106#> of size <#107#>magstep1<#107#> at a resolution
of #math21#240×216 is searched for in the library <#108#>PK0288x0259<#108#>
or as a PK-file with the name <#109#>288x259/cmr10.288pk<#109#>.
