Windows 7: How do I stop my printer printing out instructions for Two-Sided print

I have recently installed Windows 7 Home Premium 32bit and when I print anything on my Lexmark E120 laser printer and select Two-Sided printing, it prints out instructions for doing this.
As I already know how to use my printer, I would like to stop it printing out instructions and wasting paper. Does any one know how to do this?

try resetting the printer Or Holding down the Power Button.

Some time ago, I had a printer that did the same thing. There was a setting someplace where I could choose to not let it do that. I think it was in the same area where I would choose to print on both sides. Check your settings. It should be somewhere where you can turn it off.

Never had a Lexmark printer, so I actually no nothing about it firsthand.

But do you think this is coming from the PC's driver, or from the setup of the printer itself using its own display panel and settings dialog button?

I know what HP printer drivers look like when you do Start -> Devices and Printers, and then right-click on my HP printer and select "Printer properties". If I then click on the Device Settings tab and explore the various options, and also the Advanced tab (and then also click the Printing Defaults button to go deeper into the settings) and look around there as well, I discover nothing that appears related to duplex-mode "instruction page" available for selection or not.

This suggests it might be coming from your printer itself, and exploring the manual for setup instructions or calling Lexmark for support might reveal what you have to change in its setup to disable this extra instruction page from printing whenever you do choose to print in duplex mode.

Perhaps this is something like specifying the wrong paper (in the default or explicit preferences setup), say for "A4" instead of "Letter". If you then try to print something in "Letter" when "A4" is the default you have to push the START button on the printer each time you print, to tell the printer that you've now installed the non-default paper type. Maybe this duplex-instruction issue is similar, and can be eliminated if you just set the default printer preferences on the driver to say that duplex-mode is the default. You can always choose to NOT print in duplex mode for a given job if you do want one-sided printing. Or, just let it print the single page in duplex mode and let the paper flow as if you printed on both sides, but only one side will actually get printed since your document only has one side.

Sorry I can't be any more helpful than this.
