I just bought a printer for my mac (running OS X) and installed the software and drivers that were on the disk. I test printed a page and it printed beautifully. I also printed a document from Text Edit. However, when I tried to print a Word document, I received an error message saying that I needed to either check the test center to make sure that my printer was selected or to change the printer settings. I have reinstalled the software twice now, and the error message is the same. And yes, my printer is selected. I have two questions. How do I adjust my “printer settings” so that I can print from word? If that does not work, what else could be the problem?

Check paper size settings first, cos if the A4 / Letter setting is not matched to paper it could kick up an error
