Yup!  The driver won't work with VM on.  The HP people say
they are working on it, but they seem to be not quite sure 
if the problem is with System 7 or the driver.  So, an 
upgrade/fix is uncertain.
However, it seems to work fine if you turn BOTH VM and 32-bit
addressing ON.  I haven't done extensive testing on that but
I've printed something with no trouble at all.
Good luck!
