I've got a Bell Microproducts Hammer N1200 - it's a little 2-bay SATA NAS device. It runs Busybox 1.1.1 amongst some other mumbo jumbo. Essentially, it shares two SATA drives and up to two USB ports. USB ports can be either external drives or printers. My issue is with printers.
I have three XP 32-bit devices that all connect just fine to the thing. Browse to the system's IP, double click on the printer share, select the correct driver, done.
I have one Win7RC 64-bit that behaves exactly the same way.
I have one Vista 64-bit device that is barely functional doing the same thing. It takes about five minutes to browse the device, five minutes to double-click on the printer share, and perhaps 8-10 minutes after selecting the correct driver before it's installed. It takes about 10-15 minutes to print a test page. Most applications error out before printing. It's useless.
I have been setting this system up quickly over the last day... I am virtually positive that the printer worked properly before installing SP2 (SP1 was slipstreamed).
I've got no more ideas... found a couple sites with a couple ideas, but nothing has panned out. Anyone have any thoughts?
