Sorry about the misspelled word printer in topic heading but I cannot correct it. As posted on the HP Forum HP will not released drivers or new software for Windows 7 until January 2010 due to problems. They state to use the Windows 7 generic printer driver which will leave you with a lot of missing functions for your printer. Presently there is not a specific date in January yet for the release but I have installed 23 HP printers with all functions using the Windows 7 Compatibility Mode Vista (remember you must have the current updated drivers and software from HP). If you have already installed the HP printer you must uninstall all to include drivers, and software before reinstalling to prevent any conflicts. If you have the old HP Printer Solution Center make sure you update to the newest one. Follow the same instructions as if you were installing the printer out of box, ie, do not turn printer on or connect USB device until you are asked to on the screen. Make sure you connect the USB device to the printer first and then the computer. DO NOT attempt to set up wireless until all is installed and working first. The only problem I have encountered and is also on the HP Forum is Iris the scan program for HP printers is not saving documents to the computer in certain formats but since I use OmniPage I did not delve into this issue. After you have all installed and check that they work then proceed to install and connect the wireless if your HP printer supports this. Of course anyone can wait and wait and wait until HP finally releases all so your printer will work with all functions. My printer works fine with on line printing or off line except for the minor HP Iris scan problem.
