Sorry for the delay, but I was on vacations for 2 weeks, and
only today, our vendor technical support (miracle!!!!) was the
one to provide the answer.
The original question:

I went on testing and then I sent this:

Answer:
*******
What I was doing was to define the plotter as all of the
provided types for the printers, but in order to have a filter
who does not do nothing, what I had to do was:
In the admintool, choose the printer type other
and manually type there "unkonwn".
Whith this, no filter will be used.

The answers I got from the list were:
- Try printing from the Print Tool.
Of course I had the same problem
- To define the Plotter as an HPPrinter.
That was what I was doing, and that was the mistake.
- Install HP Jetadmin.
That won't work because JetAdmin is for network printers,
and the plotter was connected directly to the Sun box.
- Try to print using -T hpgl
Didn't work
- Write my own filter.
That one might have worked, but I felt lazy about it,
and instinctively knew that there should be a filter like that
in the OS.
