These fellows ask about Hypercard and non-Apple printer drivers:
	tgl@ZOG.CS.CMU.EDU and
	woody@tybalt.caltech.edu (William Edward Woody)

Hypercard makes use of a new print manager call PrGeneral which is documented
in IM V-410.  It is present in Imagewriter drivers >= 2.5 and LaserWriter
drivers >= 4.0, and not in any third party drivers (including SoftStyle's HP
Thinkjet driver that I have). 

Any drivers that intend for Hypercard to use them MUST implement the PrGeneral 
call.

Second:

edmoy@violet.berkeley.edu asks about odd address alignment on the Mac Plus
versus the Mac II. 

The 68000 has an exception condition raised when an odd memory reference
occurs.  The 68020 does not.  That accounts for the difference in behavior you
noticed between the two machines.
