Hard to say. Some USB products react differently depending on how you
connect them. I've got a USB disk enclosure that connects as USB 1.1 if
I make the connection first and then switch it on. 

If I switch it on first and then make the connection it connects as USB
2.0.

Try it and see if it helps.

I don't think this is even _supposed_ to work. It's been a while since
you could just cat a file to a printer port. :-)

If you look at the openprinting.org page for this printer, you'll see
that this printer requires the hplip driver; 
http://openprinting.org/show_printer.cgi?recnum=HP-DeskJet_3840

You can install it from ports. It is in print/hplip.

Make sure that the hplip driver in installed.

Make sure that you have the right permissions set for /dev/ulpt0. 
See /usr/ports/print/cups-base/pkg-message

Have a look at the cups logfiles in /var/log/cups.
