Printer Setup (all versions):
If you're printing checks, do not forget to select the correct check style.
(Optional) If you are printing a logo (image) on your checks, click the Logo button and make sure that your logo image file is still where Quicken expects it to be. Also choose the proper features for printing partial pages when using 3-per-page stock. Users of continuous forms on dot matrix printers: Be sure to select "Continuous Forms" instead of "Page-oriented". Laser / inkjet sheet-fed printers: select paper size 8.5*11", standard paper. Do not use any "Auto detect" or photo print settings. If checks print OK on one computer but do not align properly on another computer, compare printer settings and printer port selections.
Make sure that at least one of your printers is marked as Windows Default Printer ... doesn't have to be the one you want to use with Quicken, but you need at least one marked Default Printer
In some of the newer versions of Windows 10 you may also need to do this: Go into Windows Settings or Control Panel, Printers & Scanners. Uncheck "Let Windows manage my default printer".
