If you set your printer to use polling instead of a set IRQ you should not have any problems. I have very few IRQ's avail on my notebook so I set the printer to polled mode(removed IRQ definition from the kernel) and I use my network card with IRQ 7 without any problems.

My sound card on my home machine uses two IRQ's (an old ProAudio Spectrum) and they conflict with the parallel port IRQ's. I built a kernel with ALLOW_CONFLICTS_IOADDR, ALLOW_CONFLICT_IRQ, and ALLOW_CONFLICT_DMA and I seem to be able to configure the kernel on bootup (with -c) to use one set of IRQ's etc. or the other, so I can either print or get sound on any given boot but not both.
