printing under QNX RTP

I have problems to establish a HP Laserjet 6L under QNX RTP (03/09)
It seems it is not automatically dedected by the enumerator, so I
red the “Printer installation and configuration manual”
The problem is that in my installation there is no /usr/photon/print
directory and also I couldn’t find Pp.pcl.
Solutions for this problem are welcom. Thanks in advance
