Printer (HP Officejet 6200) is wired to Vista Home Basic (2007 w/ SP2), printer sharing enabled via Netgear router. Laptop-1 (Win 7 Home Premium, 2009, w/SP1) and Laptop-2 (Vista Home Premium, 2007, w/ SP2) "see" printer via network. When I print anything Print Manager instantly reports "Error Printing". I am clueless as to troubleshoot. Have run Printer Troubleshoot app. - No help. Have spent too much time trying to fix. Any advice would be much appreciated.
