It doesn't know, and the error is lost. This is why pap implements the
protocol correctly. At some point, Apple (or Adobe, probably) changed
the Laserwriter driver to not wait for the printer's EOF. This made
Mac printing suddenly faster, since a job could be loaded in the
printer's memory, long before the engine ripped it. Printers that came
out after this change (particularly those using Abode's PAP
implementation) would sometimes get confused and never send EOF. Very
frustrating, as this was when just about the time we were adding
accounting to netatalk. In any case, we changed the default in psf to
reduce the number of "why does lpd hang" messages we get to the list.
