Defining a network printer as AS/400 *IPDS printer

I am new to the AS/400.  Can anyone assist me in defining a network printer
as an *IPDS printer?  My printer is an HP 4000TN.  IBM documentation makes
no references to this printer and the HP documentation has no references to
AS/400.  Through much  trial-and-error we have managed to define this
printer to the AS/400 as a 3812-1, but I would like the printer to be
defined as *IPDS so that I would have the capability to generate forms
overlays to this printer.

The current definition which works is (from the RTVCFGSRC command):
CRTDEVPRT DEVD(PRTGVLPUR) DEVCLS(*LAN) TYPE(3812) MODEL(1) +
         LANATTACH(*IP) PORT(9100) ATTACH(*DIRECT) ONLINE(*YES) +
         FONT(11 *NONE) FORMFEED(*AUTOCUT) SEPDRAWER(*FILE) +
         PRTERRMSG(*INQ) MSGQ(*LIBL/QSYSOPR) ACTTMR(170) +
         INACTTMR(*SEC15) LINESPEED(19200) WORDLEN(8) +
         PARITY(*NONE) STOPBITS(1) TRANSFORM(*YES) MFRTYPMDL(*HP4) +
         PPRSRC1(*LETTER) PPRSRC2(*LETTER) ENVELOPE(*NUMBER10) +
         ASCII899(*NO) IMGCFG(*NONE) CHRID(*SYSVAL) +
         RMTLOCNAME('10.20.1.34') SYSDRVPGM(*HPPJLDRV) +
