PrintManager v39 is a so called printer-spooler, it intercepts all printer.
device calls to the parallel-/serial.device and saves the printer specific
raw data to a file. This way, programs sending data to the printer don't have
to wait for the slow printer to continue. PrintManager also gives you some
control over the data send to the printer. You can even print files directly
from inside PrintManager using the datatypes-system.
