> Have Aspect 3000 computer currently sending output to an HP 7550 Plus
> plotter via a DB-25 serial connection. Also have an HP 4000 T laser printer
> that understands HPGL-2 plotter language and has a nine pin serial port. Have
> HP cable that changes DB-25 to DB-9. The cable pin outs are as follows:
>
> Computer DB-25 Printer DB-9

> 2 - Transmit Data 3 - Receive Data
> 20 - Data Terminal Ready 4 - Data Set Ready
> 7 - Ground 5 - Ground
> 6 - Data Set Ready 6 - Data Terminal Ready
> 5 - Clear To Send 8 - Data Terminal Ready

> Have tried connecting the Aspect 3000 to the HP 4000 T using the above serial
> cable. When we attempt to send data to the printer, the Aspect 3000
> computer makes the attempt and then times out without recognizing the
> printer. The printer never indicates that any communication has been
> attempted.
>
> Is there a way to get the above equipment connected and working?
>
> Will post summary of responces if useful.
