More on printing!

[gdesroch@slate.mines.colorado.edu (DESROCHERS GARY FREDERIC)]

    O.K.  I have a good interface for GSOS printer drivers.  Now for the 
next step.(no pun intended)

     I am now in ProDOS 8.  I want to identify a printer and I want to
exclude all the other ports that could not possibly be printers.  How can I
do this.  Remember this is only on the IIgs.  The firmware reference says
that it can only be in slots one and two.  Is this the case?  Let's
speculate that it isn't the case.  Let's step through the list of block
devices for ProDOS 8.  Let's say I get:

slot 1 drive 1 = block device
slot 1 drive 2 = block device
slot 2 drive 2 = block device
slot 3 drive 2 = block device

   This is not a real list by any methods.  All I am trying to get at is
that if there is a block device defined for slot 1 drive 1 can I actually
say that there is no printer there?  But could I also say that there may be
a printer at slot 2 because nothing is taking up drive 1.

    I just through this together right now to see what I could come up
with.  Any comments or suggestions on how you have done it or how you think
it should be done would be appreciated.
