The Laserwriter requires some form of flow control to avoid overruns.
By default, it uses XON/XOFF; the PC BIOS contains no knowledge of this.
The PC, by default, can only deal with hardware (DTR) flowcontrol, and this
only because it's really in the hardware, not the software.

However, nearly every spooler I have ever seen supports XON/XOFF.  Most people
will be using a spooler, so I think this is the answer.  Also, many programs
that do spooling themselves (such as wordprocessors) support XON/XOFF.
