My usb printer is on another machine, and my Debian installs print over the network using ipp, so I can't directly help with Tong's problem in setting up a local printer on Lenny. I wonder if the necessary usb host controller module is loaded. On my machine with the usb printer on it, /sbin/lsmod shows the uhci-hcd module loaded, and the usb printer is the only usb device on that machine. There are 2 other usb host controllers, ehci-hcd, and ohci-hcd, and depending on what other usb devices you have connected to the machine, you may find more than one of these usb host controllers loaded. Could you send the output of lsmod please. Also the output of lsusb would be usefull, just to see if Lenny can see the printer. Another thought. Is the printer plugged into an unpowered USB hub. I have had problems with those. If so plug the printer directly into a USB port on the machine 2ยข worth of guesswork.
