Your kernel set-up looks reasonable to me.

I don't have parallel port support generated into my system, as I don't
have a parallel printer.

On a Centos host with parallel port support, 2.6.18 kernel:

CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
CONFIG_PARPORT_SERIAL=m
# CONFIG_PARPORT_PC_FIFO is not set
# CONFIG_PARPORT_PC_SUPERIO is not set
CONFIG_PARPORT_PC_PCMCIA=m
CONFIG_PARPORT_NOT_PC=y
# CONFIG_PARPORT_GSC is not set
# CONFIG_PARPORT_AX88796 is not set
CONFIG_PARPORT_1284=y
CONFIG_PARIDE_PARPORT=m
CONFIG_I2C_PARPORT=m
CONFIG_I2C_PARPORT_LIGHT=m

ls /dev/par* shows:

/dev/par0  /dev/parport0  /dev/parport1  /dev/parport2  /dev/parport3

Do you have a standard parallel port, or a special IO card?

Have you modified /etc/udev.d rules? I have these (unmodified) entries:

rules.d/50-udev.rules:KERNEL=="lp*",            NAME="%k", GROUP="lp"
rules.d/50-udev.rules:KERNEL=="parport*",       NAME="%k", GROUP="lp"

I'm puzzled by this, as your /dev/lp0 print test worked.

The only other suggestion I have would be to try:

hp-setup -i /dev/lp0

Don't know if hp-setup will accept this, might be worth having a go.
