Sorry that solution won't work here because the output for the printer
and print commands are embedded in a C++ program that are executed as
part of text based programs and also because five different cups clients
are using the setup at the same time. If you have multiple spoolers
running for the same physical printer with multiple users I am pretty
sure it would wreck havoc with your print jobs. Just a caution.
