Unable To Select A Printer

Running WindowsXP with SP2. Word 2003. OE6. IE6. Have HP 1210 all-in-one and Canon BJC2010. Both work fine. Problem when I wish to print a document, or e-mail text, or whatever, and click on ctrl+P, or use File menu, or whatever, I always get the printer I do not want to use. I use the HP for scanning and copying, particularly in color, and prefer the Canon for regular printing from Word or OE or IE. But somehow each time, I get the HP rather than the Canon. Now on the window for printing they always have a list of options, so this is not a crisis, just a request to lower the nuisance titre a bit. There should be a place to go to select a default printer.
