Probably, the driver does something special to the USB port, rather
than simply streaming the job out to it.  Many printers are doing this
now, whether to pass status information back and forth, or to allow
rudimentary remote management.  In this case, it sounds like the
'print multiple' command is passed by the datastream, but instead
undoing it with a 'print one' command, they decided to just 'reset'
the printer, and implement the 'reset' by directly writing to the
USB port.
