   Are you sure the cable is OK? Bit 6 seems to be stuck on.

   Between each line, you're seeing "MJ". This should be ^M^J, an ordinary
CR/LF pair. The difference between the two is bit 6, 0x40. Spaces start
out as 0x20 and end up as (0x20 | 0x40 = 0x60), which is the back quote.

   The text comes out OK because lowercase letters already have bit 6 set
and are therefore not affected.

   It sounds like a hardware problem, either in the cable or the parallel
port itself. If this bug were in the software, it would have been fixed
long ago.
