HP DJ 3550

[Mikhail TSaplin]

HI ALL

I have hp deskjet 3550 usb printer, and freebsd 5.1
ulpt determine this:
	ulpt0: hp deskjet 3500, rev 2.00/1.00, addr 2, iclass 7/1
	ulpt0: using bi-directional mode
But when i issue "lptest > /dev/ulpt0" or "lptest > /dev/unlpt0",
nothing happens. 

Must i send HP-oriented special text to device?
And is there anybody who have this printer working properly on freebsd?
