Updated to 10.6.5 and appear to have lost my WiFi Brother MFC-790CW printer. Tried adding it as a new printer but it cannot find it on the network whereas I can print from both an iPad and an iPhone with the "Brother iPrint & Scan" app???

The odd thing is that it adds the Printer OK [in add Printer under system preferences] but when a document is sent to print fails to connect with printer???

Anyone else having a similar problem?
