If you have a printer that has the paper tray below the print head, 
then after printing one page, take the page and insert it back into
the tray containing the blank sheets. Do not turn over or rotate the sheet.


If you have a printer that has the paper sitting above the print head,
take the printed page and place it back onto the paper carrier in such a way
that the printed side is now underneath and turned around 180 degrees.
This means that the start of the print for the first page is now underneath
and at the top of the sheet - look at the underside of that sheet.
Typical printers for example are Canon, Lexmark, Epson.
