redirection of printers fail on windows 7 machine but works fine on office xp machine when i try connecting using rdp from windows 7 machine at home to office network.

I have windows 7 machine that i use to rdp to my office machines, my printers are redirected on xp machine in office but redirection fails for windows 7 machine in office. we have sbs 2011 server. ans use remote web access to connect to office machines. is there any setting that needs to be configured on sbs. i did try adding printerdrivers for canon mx330 printer on office machine that is connected to my home machine and is required to be redirected.
