No duplex printing option via network printer

[samrat_rao]

My desktop was configured by the help-desk guys to print from a printer connected through the local network. They said that the drivers will be automatically taken from the server. Now i am seeing that only single sided printouts are being taken. Both Evince and Okular are not allowing duplex printing. So i guess that there must be some system-wide setting that i am unable to modify.

Could you please suggest what i should do next?

Would request you to consider that i am not comfortable with internet related protocols and so i might take some time to grasp the technical terms you might be telling me.

The default setting of the printer server itself was to print one side per sheet only. So i was getting single sided printouts. Funnily, many other people were able to get duplex printouts despite the printer having duplex setting disabled.
