Abstract:
1. A system for routing a print job from a source computer coupled to a first network in a first security domain to a networked printer coupled to a second network in a second different security domain or to a networked printer server coupled to the second network, comprising: a send platform computer in the first security domain coupled to the first network, the send platform having an output and configured to receive a print job from the source computer via the first network, to convert the received print job into a print file, and to forward the print file on the output; a one-way data link having an input coupled to the output of the send platform computer and an output, the one-way data link configured to transfer data only from the input to the output and to prevent any signal from passing from the output to the input; a print spooling platform computer in the second security domain coupled to the networked printer via the second network and only coupled to the send platform computer via an input coupled to the output of the one-way data link, the print spooling platform computer configured to receive the print file via the input from the one-way data link, to forward the print file as a network print job to the networked printer or to the networked printer server.
