The installation keeps failing on my windows 7 os for my hp deskjet 3940, i followed all the instructions and made sure i had an internet connection and the printer was on. i really need to print. how do i get this to work?

OK, If you cannot get a Win 7 exclusive driver, then try to Install as Administrator, try installing everything in XP SP2 COMPATIBILITY Mode too, also as Administrator, If a 64 bit system, you must disable digital driver signing at every boot up, by pressing F8 and selecting that option at bottom of the list. As well. Get the latest software from link below. http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?prodNameId=445479&lang=en&cc=us&taskId=135&prodTypeId=18972&prodSeriesId=445475
