[comp.os.cpm] Printer mystery...

RICHARD@KUHUB.CC.UKANS.EDU (RICHARD KERSHENBAUM) (07/19/88)

I bought a used printer last weekend to use with my Kaypro 1.  It's a Radio
Shack LP VIII.  (Don't laugh -- it was cheap and apparently in great shape.)
Plugged into the parallel port on the Kaypro, it prints nearly every character
twice in ssuucceessiioonn -- not a pretty sight!  Except....when using the
K-1 screen dump program (from simtel20), it prints perfectly.  Printing
from WordStar, PIP and anything else I've tried results in doubled characters.

I connected the printer to a friend's PC-clone, and it prints perfectly there.
Suspecting a problem with my centronics port, I connected the same friend's
Okidata 182 to the Kaypro.  Perfect results again.  So, all the *pieces* work
independently, but the combination of the Kaypro and the LP VIII fails --
except using the screen dump program. 

Has anyone seen this sort of problem?  Is there any cure, or are these devices
just flat incompatible??

I'd sure appreciate any help....
