Hi Don,
Welcome to the HP Forum.
Don says, "have installed the fix three times"
- Which fix have you installed?
Don says, "printer still prints this extra page when I plug in usb printer plug"
- Does the printer NOT print an extra page when you use the printer wireless? That is, does the extra page only print when you connect the printer with the USB cable??
- What is printed on "this extra page"? Is it words, lines, pictures, descriptions, blank?
- Does the extra page come with every print job or only certain types of jobs, say perhaps jobs coming from Office Word? If yes, this is fixed when you open a Word document > File > Display > Printing Options > UNCHECK "Print document properties" > OK
- Do you have the Full Feature Software installed for the Printer?
