Now that Richard's fixed his signature, we have a better chance of
mailing him directly, but I thought the following might be of more
general interest.

How well the Laserbrain emulates an Epson depends on several things,
including how good the printer driver of your applications program is,
and what fonts you have installed.

On the first point, where I work we nearly despaired when we got the
Laserbrain and tried printing the test document from First Word Plus
(UK v3.14).  Hardly any of the style features worked, and after
printing the character table the rest of the document was printed in
the tiny 'York 16' default font.  We later found out that the supplied
PRINTER.CFG file was for the wrong version of First Word Plus.  (I
suspect Atari UK had simply redistributed an out-of-date German
version, but everyone knows how bad they are, so I'll stop flaming
them.)  After we took the PRINTER.HEX file and reinstalled the .CFG
file, all was well.  Similarly, with WordPerfect ST: when we tried it
with Laserbrain and the WP Epson FX80 driver, we got rubbish, and only
with the latest (Aug 89) version of WordPerfect, which comes with a
dedicated Laserbrain driver, have we had success.

On the second point, the number of 'style features' you get depends on
the set of fonts you have installed.  With the supplied ELITE.DRF
(DRF=Druckerfont??  German again??) file, you can get bold, and
italics, but not bold italics, and there's no condensed font.  It's
not too difficult to add fonts to the file, but they all take up
space.  ELITE.DRF is 350k, and you could easily double that size if
you wanted a full set.  You might need a 500k file to cover 99% of
your needs.

Apart from that, it works pretty well.  Except that it occasionally
locks up, or starts printing the same few lines all down a page, or
throws a page in unexpected places.  I'm not an expert, so I don't
know if this is a Laserbrain fault or a TOS fault or something to do
with the timing of the Atari's DMA channel (I suspect the latter, but
I'm not sure.)  It is, however, for all its faults a great improvement
on the Diablo emulator.  To begin with, it actually comes with some
documentation!

I hope this is some help to Laserbrain users.  I'd like to see the PD
libraries carry some disks with better-thought-out font sets.
