One possibility is that your 586 is too fast, particularly if the LPT port is genuinely on the PCI bus (rather than being on an ISA bus bridged from it). Unfortunately, the lp driver has to rely on software timing loops for handshaking/timeout. You could try increasing the values of LPMAXSPIN1 and LPMAXSPIN2 in /sys/i386/isa/lpt.c, eg. by inserting in your kernel config options "LPMAXSPIN1=16000" options "LPMAXSPIN2=2000" > The PCI board is a Gigabit GA-588ATS.

FreeBSD does not activate any of the advanced modes, so all will behave the same.
