I think Courier (an ADOBE font) is in fact a 'stroked font', I don't
know of any other 'stroked fonts' by ADOBE. BTW is there a reason for
this and does Courier by its uniqueness become a 'toothache-of-a-font'
because of it?

How much interpreter overhead goes into decryption in comparison to
a non-ABOBE font? I'm not being troublesome...just curious ;-)

Our graphic arts department consists of 9 Mac SE's, an LW+, and a L-300.
Each SE has a 20 meg internal hard disk. We use a relatively large number
of fonts in producing custom labels and price marking products. These fonts
'exist' in three places in my understanding.

1) Bit mapped representations are installed in the SYSTEM
   Question: Does the new FOND type resource allow you to have only
   one point size installed without loss of screen appearance? This
   in contrast to the way we now are set up with several point sizes
   installed for each font?

2) 'Printer' fonts dragged to the SYSTEM folder from the font release
    disks so they can be 'called up' by an application for downloading.

3) Pre-rasterized versions installed on the L-300 harddisk
   Question: Why do we need the printer fonts in each SYSTEM folder if
   they are _there_ on the L-300 harddisk?

   Question: Assuming we do need them in _a_ SYSTEM folder. Could they
   be in a volume say, published on TOPs and when a station needed them
   could they be routed through LocalTalk to that station? i.e. Is
   a 'font server' product available which will allow me to keep all
   my 'printer font' files in one place? As it is now over 3 meg on each
   station harddisk is sucked up by the 'printer font' files. It is
   very annoying and seems redundant in light of LAN capabilities and/or
   the answer to number 3 above. (sorry if this seems a bit muddled, but
   I'm a bit fuzzy on the mechanics of it all). To clarify a point, why
   can't the application interogate the harddisk on the L-300 first and
   say 'Hey, I got it already on the disk, who cares what's in YOUR SYSTEM
   folder.'? All the MAC wants is the 'bit maps' for screen representation
   it's the printer that wants the PS, and its got 'um? Right? I should
   be able to empty everybody's SYSTEM folders of all those redundant files
   (but why do I suspect I'm mistaken...;-) The only reason I can think of
   to keep them around is for the LW+ when we proof to it, but that could
   be on one machine strictly for proofing.

I know this is very long winded but its worth roughly 27 meg of work space
to me.

(Another unrelated item which you might route to the appropriate person.
I understood ADOBE was coming out with an OCR-B. In fact I'm a beta test
site for it. I've written a program which produces bar codes as double-
clickable Illustrator files which we then build labels around. The problem
is I have to use Helvetica for human readable text. According to UPC specs
the font should be OCR-B. Any movement here? )

Thanks for any help.
