Under /proc there are all sorts of informational files. You can few them opening a terminal or shell and type cd /proc and then you can issue, for example, cat dma to see what dma channels are in use. cat ioports will tell you what ports are used by what devices and cat interrupts will tell you the same for IRQs.
There should also be one there call isapnp. It's longer, and you may want to use less instead of cat to view it. Mine has my soundblaster card listed with the settings in use at the top (followed by a lot of alternate settings that aren't used). What is useful about it is that it should show you all of the optional IRQs, DMA and ioports that can be used by your card. That way if one of them are in conflict, you know what you can change. I'm not sure the printer port uses a dma channel, so that may not be the problem. It still sounds like some kind of IRQ problem. When you were in your CMOS, did you notice if the PNP settings were set for auto or manual (where you could reserve specific IRQs). If manual, there might not be an available IRQ to use without sharing, so you might try auto and see.
