I have a canon pixma ip4300 printer and a Draytek vigor 2800 router. The draytek has an LPR printserver built in.
When I connect the printer to the router, I can use the printer from different windows machines, but bidirectional communication doesn't seem to work, even though the 'tcp printer port' is configured as such. The bidirectional communication is used for things like reporting ink levels and duplex printing.
Is there any way to get this working using an LPR printserver?
