Hi. I have a HP Photosmart C6180 all in one printer which has wi-fi capabilities. It is connected to my home network, as is my laptop. I reformatted my laptop recently, and set up the printer simply by adding a network printer using windows..Printers and Faxes -> Add a Printer. It worked for a while but suddenly stopped working. I tried printing something this morning but an error message came out..printer spooler service not started or something. I went to check services.msc but the service was started..restarting it did not solve the problem. I then uninstalled the printer. Now I can't install it back. When I try to Add a Printer..choose network printer..it scans but doesn't find anything..only Microsoft Windows Network..I can't find my printer listed there..strange because it still worked last week. I tried entering the IP address of my printer into my browser and the configuration/summary page came out. Pinging it on cmd.exe also works...but windows just cant seem to locate the printer. Shouldnt be a firewall problem since I had windows firewall on ever since I installed windows XP and it worked fine before. Are there any additional services that need to be started? Any ideas?
