Q: everytime I turn on a printer and have it connected it prints a page with a numeral in the top left corner or a few numerls

    I have closed all print commands that I know of and it still spits out a page with 1 to 4 numerals . Then it feeds another page to the ready to print and waits a while before going ahead and continuing to finsh turning the page out.   This takes place on more than 1 Printer.

     What do I do to find this hidden command and delete it?
