The same happens whether I use lptest against the device or samba with 
the appropriate drivers: the laser printer starts to make some noise and 
warms up like it's going to print something, and doesn't print anything 
in the end.  I tried both, /dev/ulpt0 and /dev/ulpn0.

Before, I didn't see I was having those in the logs,

ulpt0: offline
ulpt0: output error

I've also seen this error below on another occasion, I cannot reproduce 
it.  It was probably caused by my attempt to reconnect the USB cable 
physically.

uhub0: device problem, disabling port 4

Anyway I've disabled ACPI at boot time and I don't get any of those for 
now anymore, while the main issue remains.

Well I was using good old HP Laserjet 4L before, which I think, aren't 
postscript either, and it was still printing the text I sent to the 
device directly (even though there was some indentation issues, the 
drivers being mandatory to print other documents).  My point being, is 
it truly mandatory for the printer to be postscript compatible to be 
able to do that (lptest > /dev/ulp{t,n}0) or LPD/samba with a raw 
printacap entry?

Thanks
