I believe you should be able to find the PCL codexes on the HP website.
As for connectivity, DB3 (unless you have network ver) will look for the local printer port. If this is the case you should be able to pass the PCL codes by using the SET PRINT.
I'll attempt a screen shot of DB3+ help below, hopefully you'll be able to see it:

SET PRINT
SET PRINT
---------
Syntax : SET PRINTER TO [LPT1/LPT2/LPT3] / [COM1/COM2] /
[\\<computer name>\<device>=LPTx]
SET PRINT on/OFF
Description : Does/does not direct all output not formatted with the
@...SAY command to the printer. SET PRINTER TO directs the
output to a specific printer or DOS device. The first two
forms of SET PRINTER TO are for local print devices. The third
is for a network device. SET PRINTER TO by itself resets to
the default device (both) and ends the spool process (network).

Try using the HELP command and type in SET TO as the search key.
