Hello, Tom.  I heard you talking to RJT about - -

 TW>  I have an old Epson ActionLaser 1500 running on a Aotomatic Pronter
 TW> switch. But most newer Laser Printers don't like Switched. OR shaing of

 TW> in fact I am about to install a HP LaserJet 1200 for a group and the

Aaaahh - - good old Windows.  It has to get its tentacles all into and
around everything.

 TW> And HP has a Special Warning strongly discourging the use of Manual
 TW> Switch boxes because of the chance of a Switching spike damage to the
 TW> printer input card.

FWIW, HP have their own brand of printer autoswitch.  One here is an
"H-P Jetdirect auto switch For sharing 4 devices", so I think it will do
either 4 to one or one to 4.  I bought it for compatibility with the
Deskjet 890C.  It may be older than when they started using model
numbers like 1200 for the Laserjets.  My newest laserprinter is a
little LJ 4L, and it works OK with the HP autoswitch.  I think I have a
manual for it around here somewhere, but can't find it right now, so I
can't say what they may have said about using it with their laserjet
printers.
