Okay maybe primary and secondary classes are just the way I think of them  (
we are a
predominantly a site using various flavours of Unix, so our 'solutions' may
not be
as esoteric as long term HP3000 sites would be ) this however, as relatively
late
arrivals into this environment, is the way we configure network printers :-

In SYSGEN/IO :-

     io> AD LDEV=367;PATH=NONE;ID=HPTCPJD;CLASS=NETLP TLLASER2

    io> LD CLASS=NETLP
 LDEV: 100/115 NMMGR

 LDEV:   365  DEVNAME:                    OUTDEV:        0   MODE:
OS
   ID: HPTCPJD                            RSIZE:        66   DEVTYPE: PP

 PATH: NONE                               MPETYPE:      32   MPESUBTYPE:  0

CLASS: NETLP    TSLASER1 TSGHP



 LDEV:   366  DEVNAME:                    OUTDEV:        0   MODE:
OS
   ID: HPTCPJD                            RSIZE:        66   DEVTYPE: PP

 PATH: NONE                               MPETYPE:      32   MPESUBTYPE:  0

CLASS: NETLP    TKLASER1



 LDEV:   367  DEVNAME:                    OUTDEV:        0   MODE:
OS
   ID: HPTCPJD                            RSIZE:        66   DEVTYPE: PP

 PATH: NONE                               MPETYPE:      32   MPESUBTYPE:  0

CLASS: NETLP    TKLASER2


.....................   and so on,

 Then we associate this device with its ip-address


SYS:PRINT NPCONFIG.PUB.SYS
global (setup_file = PCLLPSGA.HPENV.SYS   # SGA print envmt.
        banner_header = FALSE
        banner_trailer = FALSE
        pjl_supported = FALSE
        jam_recovery = TRUE
        data_timeout = 20
        poll_interval = 25)
360 (network_address = 100.0.9.160  # LPLASER.
     setup_file = PCLLPSGA.HPENV.SYS
     message_interval = 60)
365 (network_address = 10.97.31.10  # NETLP.
     setup_file = PCLLPSGA.HPENV.SYS
     message_interval = 60)
366 (NETWORK_ADDRESS=106.1.2.1 # NETLP
     SETUP_FILE=PCLLPSGA.HPENV.SYS
    MESSAGE_INTERVAL=60)
367 (NETWORK_ADDRESS=106.1.2.2 # NETLP
     SETUP_FILE=PCLLPSGA.HPENV.SYS
    MESSAGE_INTERVAL=60)
368 (NETWORK_ADDRESS=90.1.2.1 # NETLP
     SETUP_FILE=PCLLPSGA.HPENV.SYS
    MESSAGE_INTERVAL=60
    RUN_PRIORITY=BS)
.
........  etc



We have 45 network printers configured this way.  We don't use the DTC at
all.

I can refer to the printer's device number 367, the user nominated printer
name TKLASER2
or the 'global' class name NETLP.
