As the messages try point out, ppmtolss16 does not understand command
line arguments, it expects to read the PPM/PNM file from the standard
input and writes the result to the standard output.

So use shell redirection, and no need to sudo:

ppmtolss16 <tst.ppm >tst.lss16

Thanks a million!


I succeed to generate without any error! :)

But the picture is not displayed!

I think it's because I don't have the correct syntax!

In my syslinux.cfg file I've got

DISPLAY my_picture.lss16

The picture is 640x480 image in black and white (very simple).

Have I to do any configuration before to print it?
Or the Display line is ko ?

Thanks!
Daniel.
