configuring the parallel port

In the CMOS setup (upon turning computer on and pressing
DEL) there is an option to configure the parallel port.
In this option one can select SPP, EPP, ECP, ECPEPP, with
sub-selections 1.7, 1.9 (e.g. ECPEPP1.7). Moreover there is
an option to assign an address to IRQ7 (378) or IRQ5 (278).

I have a B&W video-camera (Connectix) and an HP laser
printer which I would like to plug in (alternatively)
to the Parallel port.

Which configuration should I choose? What do these codes
(e.g. ECPEPP) mean? The motherboard manual explains nothing.

Can you help?
Thanks

SPP is the regular "centronics" parallel port operation mode.

EPP and ECP are faster modes which allow bi-directional operation.  ECP is mostly used by new generation printers while EPP is used by other peripherals.

ECPEPP is dual mode ECP+EPP.

IRQ 7 is the default for the 1st parallel port.  Use it.
IRQ 5 is the default for the 2nd parallel port.  It may conflict with other peripherals, such as a sound card.

The printer will work fine in all modes.

The video-camera needs to send data to the PC, so EPP seems a good guess (unless it's an old peripheral).

PS, I'll be back in two days if you need more help.
It will be more helpful to know the model number of the camera and the BIOS manufacturer.
