Thank you, that is an important note! PCL backward compatibility
might be the reason why the printer accepts PCL intended for a
Laserjet 4 (I don't know, maybe PCL 3?), but doesn't actually
print anything. So the printer filter will have to explicitely
output PCL 6. That could be achieved using a different output
device for gs, or using CUPS in combination with the PPD file
provided by Brother. This of course brings you all the "joy"
of using CUPS... ;-)
