Parallel port connection between a 386i and a postscript printer

[HRC%PSUVM at icsa.rice.edu]

Recently, I try to connect a postscript printer( Mega PS writer) and my
386i through the build in parallel port.  The software that controls the
printer is 'Transcript'.  When I tried to print out something, the lpq
allways complains that the printer is offline.  But I can cat a postscript
file to /dev/lp without any problem.  Dose any one know how to solve this
problem ?  Thanks in advance !
