Yes, you may use the parallel cable connection from your printer to the rear of your PC. This will leave you with one USB port free for camera.
You can also buy a USB, PCI card that fits inside your PC, this will give you another four USB ports at the rear.
They are very easy to fit, just remove the side panel from your PC, (After switching off) and the PCI card will fit in one of the free slots.
If you need more help with this, post back to same thread and someone will talk you through the procedure. j.
