Here is a quick tip on how to conserve paper when printing to your Canon iPF.
Open the Printing Preferences for your Canon device. Then click on the second tab, which will read Page Setup.
From there, you will want to click on the box that reads Rotate Page 90 degrees (Conserve Paper). Note that the graphic of the printer on the left that shows paper coming off the machine changes the image on how the paper will print.
You can then also click on the Layout tab across the top and click on the Print Centered box to ensure that the page is printed on the center of the piece of paper.
Click Apply, then OK and these will be become your printing defaults. And they will save you paper.
