print_server needs support for this special case to not serialize
preview print jobs. More work for you, I guess ;-)

Of course, however this is not supported with the current printer
driver API. You can cancel only not already started jobs. Closing the
stream to the printer is not always sufficient to stop the printer
from printing and reseting it to wait for the next job.
Currently there is now way to tell the printer driver to stop
processing of the print job. Anyone correct me if I am wrong.
