I just bought an AXP at a local Apple Store. While there, I was told multiple printers would work, wouldn't work, not to try it and that it might work by several different employees. I bought it since I could try it and exchange it for an AXT if it didn't do this properly.
I now have an Epson 2200 and a Brother MFC 9700 connected and printing perfectly. They both show up as Bonjour printers. The only problem I had was adding the 2200 to one of our computers. For some reason I kept getting errors at first. Then I hit the Auto Select button for the drivers and it added properly. I don't know why this happened, since I used the default all along, there you go.
