It also depends on what board you buy. I have found that the industrial mother boards all tend to have a lpt port. I use the Atom boards, both ITX and industrial and if you select the correct one from the long list on offer, you will have an LPT port and mostly an PCI slot. This is not the case with all the higher end popular mother boards though.
