Dear Allessandro Rubini,
I used your barcode-Code and I think I found an error in 
the pcl.c for generating PCL-Code. 

The problem is, that the code from PS was copied. It seams, that if you want
to
draw a bar with PS you have to give the middle as starting point. In PCL you
have to provide the upper left corner.

As attachment, I'll send you a diff-file. 
If you have any questions, don't hesitate to ask me.

Greetings
Christoph Pross

PS: I hope this is the right way to tell you about it, it is the first
time for me...
