	Just your luck!  I'm trying to write printer driver too (for my
Toshiba).  I've been able to get a little farther than you ... I can do
a graphics dump, but my Amiga freezes up when the dump finishes.

	Same here.

	I guess that means your using Aztec?  I am using Aztec. 
For Aztec (3.4 at least):

	-Compile with +BCD  (large model EVERYTHING), including your assembly
	 files.  The +B option tells the compiler not to generate a 
	 reference to the startup code.  Manx 3.4 has a 'super compatibility'
	 option for cc... +p , which might be good to stick in if you have 3.4.

	-When you link everything together, the TAGS.ASM file should go first.
	 In fact, you shouldn't even have to include CL.LIB (large model C.LIB)
	 unless you use support functions from that lib.

	-Don't use DOS unless you've specifically openned the DOS library

BTW if anybody has any ideas on why my driver is dying after it completes 
a graphics dump... Or, even better, if somebody has got a driver for a
Toshiba P1340..
