Parent's Computer Upgrades

While up in Pittsburgh my parents had a few computer things they wanted me to look at. They wanted to hook up my brothers printer and scanner to their computer. I got the scanner working without issue. I then got the printer working. There was a small glitch though, the printer didn't work with DOS Wordperfect 5.1. For most this wouldn't be an issue but my dad uses it as his primary word processor. As a result this option would not work. I then went through the process of re-attaching the Citzen GX-140 that is the dot matrix work horse. To satisfy the other requirements we went out and got Canon Pixma MP500. It seems to do everything they need and then some. Hopefully it won't be too complex.
