Mac can't find printer via windows network
I have a MacBook 10.5.8, connecting to a windows 7 home network via Linksys wireless router. Mac is successfully getting to internet via this set up, but can not locate the printer (hp c4280) on the network any longer. Just seemed to stop.
I have removed printer via system pref/print&fax, downloaded latest drivers from hp, gone back in and tried to add (system pref/printer&fax/+/windows) and the workgroup is not available any longer. It used to be! I have tried to add manually through system pref/printer&fax/+/IP and input the router IP address. This adds the printer but does not print. Message is "Attempting to connect to host..., Unable to connect to printer." Keeps retrying. Printer is marked for sharing on Mac and the workgroup is set for sharing.
Other windows 7 machines (both desktop that is the wired hub of network and a wireless laptop) are printing fine. I have 3-4 hours into trying to figure out and not getting anywhere. Guess I shouldn't look for a new job as a QC analyst! Any thoughts would be appreciated!
