[comp.sys.apple] Thunderscan resolution

TMPLee@DOCKMASTER.ARPA (12/13/87)

Anyone know what the resolution of the Thunderscan for the Imagewriter
is?  (The article in A+ doesn't say.)  Is it good enough to capture
printed text (say, normal magazine/newspaper size fonts) so that one
might think of attempting character recognition on it?  (Its so new it's
probably futile to ask, but does anyone know if anyone has written the
software to digitize text, recognize the characters, and convert it to
ASCII?)

I assume they have the same capabilities as the Mac version.  On the Mac
the resolution defaults to 72DPI (same as the screen).  You can get lower
res than that (I think down to 30%) or bump it up to 400%, but it will
max out at 72*3DPI and just fake hire resolutions.

Yes, although 72DPI is not really good enough, the higher resolutions are.

This software does exist on the Mac, I've seen it advertised in MacUser, I
doubt that anything is available for the GS - yet.

I'm not sure which upsets me more; that people are so unwilling to accept       responsibility for their own actions, or that they are so eager to regulate     everyone else's.
