Probably... I can't verify that right now, but I suspect that after
sending the sequence it will accept input only on the USB port, just
as without it it will accept input only on the parallel port.
The effect is persistent until the printer is powered down, but
does survive a software reset (as sent via ESC/P sequence 1b 40).

Right. But the printcap does need to know the interface, so it
would make sense to send the sequence from the filter script.
