How did you determine this? Have you ever written a PostScript file?
I have done several of them (or written programs that output
PostScript).
I am (painfully) familiar with the internals of PostScript font
definition.
Almost all standard fonts are bitmapped, and either specified by name
and called up from the printer itself, or downloaded as long strings
of hexadecimal values in the PostScript file itself, and added to the
font list in the printer.

Now, it is true that GRAPHICS can be described by vectors, and that is
the
best way, as the graphic can be scaled arbitrarily without losing
detail.
You COULD define a font as a set of graphic images, and then set them
on the page to form text, but I've NEVER seen this done for text.

Yes, and I've learned a lot from him! Does he say something that
implies
what you said above? I'd sure like to see it.

Yes, again, the GRAPHIC content of files that are originally in vector
format
will pass through still in vector, but simple type won't!
