Setting your default printer
When I finally got printing working on my new HP5520, I discovered that apps like xpdf that print by invoking lpr directly would only work if I told them to use 'lpr -Php5520', which was a hassle. After some poking around, I discovered that the Cups web interface, at http://localhost:631/ let me set the default printer quite easily. Of course, you can do this via some config file or other, but this was easier. Here's how you do it.
