I had my ][e enhanced and indeed had the same experience with a TYMAC
parallel interface card.  I purchased a buffered printer interface card
from ORANGE MICRO (Grappler) and am very pleased with it.  The manual
from TYMAC would not be very helpful since it is a small pamphlet with
some programming tips.  The incompatibility appears to be because of
stricter adherence to standard I/O protocols in the enhanced version
which TYMAC ignored.  In the meantime, while you are deciding what to do
about your printer card, you can write a software driver to read status
at location $C1C1 and output data at $C090.  I wrote a short routine and
switched it in using P A$NNNN.
