/*
Thanks to Martin Schulte (schulte@thp.Uni-Koeln.DE) for contributing
this driver to Ghostscript. He supplied the following notes.
The device-driver (normally) returns two differnt types of Error-Conditions,
FATALS and WARNINGS. In case of a fatal, the print routine returns -1, in
case of a warning (such as paper out), a string describing the error is
printed to stdout and the output-operation is repeated after five seconds.
A problem is that not all possible errors seem to return the correct error,
under some circumstance I get the same response as if an error repeated,
that's why there is this the strange code about guessing the error.
I didn't implement asynchronous IO (yet), because "`normal"' multipage-
printings like TEX-Output seem to be printed with the maximum speed whereas
drawings normally occur as one-page outputs, where asynchronous IO doesn't
help anyway.
