Why is my printer printing smaller than normal?
Each program that you try to print from, typically has an option to adjust the scale of printing. Make sure it is set to 100%, or fit to page, or no scaling. If your scaling is correct, then you need to check your Printing Preferences. To do this in Windows 10, go to your Printers & Scanners menu in Settings.
