Airport Printing with Unsupported Printer
Print to an unsupported USB printer on Airport Extreme. This is basically a bookmark for me for the next time I need to find it.
This is one of the reasons it's so cool that Apple uses Unix as its base - by using other free tools available online, the Airport Extreme base unit goes from having a relatively small list of officially supported printers to having support even for my little crappy HP deskjet 632c.
