This config looks fine to me. I suggest you check the cabling between the
DTC port and the modem. The 25 pin DTC port does not have an RS232 profile as
the DTC expects DCD on pin 4 and outputs RTS on pin 8; so if you've used
a straight cable to connect the port to the modem, you may be inadvertently
strapping DCD high. The recommended cable for connecting a DTC port to a modem
is HP40233A.

I've supported customers who have connected Ruggedwriters to the DTC and don't
remember any particular problems. However, there are many reasons why the host
will stop spooling a serial printer. You might want to check with the local
HP office that you have the latest DTS and DTC patches.
 
Hope this helps
