I'm trying to use my old Cardco LQ1 to print from my CompuAdd AT clone
parallel port.  The Cardco LQ1 is a Silver Reed daisy wheel printer with
a built-in Cardco serial interface and has worked faithfully with my
C64.  When I connect its Centronics port to my AT parallel port, the
printer appears to reset when the AT is rebooted but will only display
the "alert" light when I use the DOS "print" command.  Does the Cardco
interface interfere with the Centronics port?  If so, is there a way to
disable it?  Or is it the case that all Centronics ports are not created
equal?  I am using a cable which successfully connects two printers at
work with ATs.  Although the pinout diagram in the Silver Reed manual
looks very similar to that of well behaved printers, I don't know enough
about parallel ports to identify problems with them.  Thanks for your
indulgence on an "almost IBM" problem.
