...sharing printer.but after installation printer not works?

You don't use the printer CD to install the printer on the wireless computer, The wireless computer will detect and automatically install the driver, if you do it correctly.

rejoin the workgroup, and use the same computername/username as before so you dont have to re-set that up again.. add a network printer in the add printer wizard and set up location for \(computer_name)(printer_name) that the printer resides on.
