How are you printing from the Mac, via appletalk? If so, where is the
switch pointing?

The 7 in the above statusdict routine just changes the 25 pin channel
to do NoParity, DTR flow control. A 3 means NoParity, Xon/Xoff
flow control. You could back the whole thing to the original state
of even-Xon/Xoff by executing the following..

servdict begin 0 exitserver
statusdict begin
25 9600 2 setsccbatch
end

But I'll bet dollars to donuts it has no effect on data streams presented
by appletalk to the 9 pin appletalk connector. Something else is wrong.
We have a slew of lasers with both WP and Apple Users switching among the
two modes.. the machines have all been set to Noparity (8 bits of data
is important).

Send mail if you still have trouble.
