Kubuntu only prints @PJL commands

I used KMenu> System Settings> Printers to set up my Brother hl1240 laser printer. I use the foomatic hl1250 (as recommended). I go through all the steps ok and it prints out what I thought was a test page during the setup wizard and I finish. But, when I try to send somthing to the printer ( a remote cups server) all it will print is the same output. No matter what I try to print, it prints the same thing.
The test page looks like this:

-12345X@PJL
@PJL JOB NAME="Ghost"
@PJL SET ECONOMODE=OFF
@PJL SET..........
...........12A12A10oxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

The last string changes each time and there are more lines preceded by "@PJL SET" but for the sake of brevity, I only show a couple.
I really would like this Kubuntu 6.0.6 install to be able to print properly over my network.
Any idea?

I use a Brother HL 1270N, my printer can print in 4 modes:
HP Laserjet 6 (PCL), BR-Scriptlevel2, Epson FX-80, IBM Proprinter XL.
You can set the emulation via a web interface e.h. http://<printer ip address>/printer/main.html. This should match the driver installed.

It seems you have the wrong driver installed for CUPS or the remreo server is misinterpreting it.
