It may be that the Printing Preferences have been set to a lower quality mode for printing images. If that is the case, the entire project will print out in that low quality. You can typically find these settings in the Printing Preferences window. That can be accessed through the following means:

  1. Click the Start button
  2. Click the Control Panel and go to Printers and Faxes. If you are on an older version of Windows, you may need to go to the Settings menu and then select the Printers option.
  3. Right-click the printer that you want to print on.
  4. Select the Printing Preferences option from the pop-up menu.

The location for the setting varies depending on the printer make/model. You should consult your printer documentation to locate these possible settings. You are looking for something that will print images in a lower quality. Also, you should check to see if there is some sort of "print quality" option for the entire document. If it is set to Draft mode, it will print the project in a lower quality.
