  Ok, if someone can think of an answer to this one I will
be forever grateful, if not generous.
    One day, my 1040ST started printing nothing but garbage
when hooked up to EITHER of my two printers, Canon PW1156
and HP DEskjet.  Through EITHER of two buffers.
    Both printers, through either buffer, work with a
Commodore 128 and an IBM-type portable.  So no problems with
printers, cables, buffers. Must be in tthe computer.
    I took it to the dealers.  It printed fine.  Must be the
software.  I brought down my software.  It printed fine. I brought
down EVERYTHING.  It printed fine.  I brought home everything. It
prints garbage.  I am at my wits end and do not feel like lugging
my system to the dealers everytime I want to write to my mummy.
   Is it possible that the level of AC current in my home is
at fault, and one bit in one chip somewhere is so weak it does not
flip?   Is it possible that electrical interference somewhere in
my home can do this?  I can't figure out why it began to do this
all of a sudden when I have changed nothing.
   There is nothing in my manuals about how to deal with demonic
possession.
