The symptoms you describe do sound like a handshaking problem.

Assuming that your cable has been built properly, the AT or XT
will drive the Laserjet just fine with X-ON/X-OFF flow control.

IF your printer is on com1:

MODE COM1:96,n,8,1,p

will configure the serial port correctly.  The 'p' sets the port
for printer handshaking.

If that still doesn't work, check the switches inside the printer
and make sure everythng is set as per the factory.

Now if that doesn't help, send me a private note and I'll send
you cable pinouts.  I tried to reply directly but my mail bounced
as undeliverable.
