Is it possible to throttle traffic coming or going to a specific ip address on a cisco 877 running : C870-ADVIPSERVICESK9-M, 12.4(15)T12, RELEASE SOFTWARE (fc3)?

Background: we have a WAN where thinclients login using citrix. When a big print job is sent, the desktop sessions suffer. So I would like to limit the traffic with source/destination the print server.

TIA.
