I have an NEC Superscript 1450N, which is a PCL/PS network laser printer. Leopard automagically detected it and had a PPD for it.
Snow Leopard can retrieve the model name when given the printer's IP address, but it uses the generic PostScript driver for it, even though it's on a big list of supported printers at apple.com. The generic driver means I can't set options in the printer setup widget. I tried finding a PPD file for it and forcing it to be used, but that just breaks printing entirely.
Software Update and the SL Optional Installs package don't find anything for this printer, even though the site seems to say there should be a better driver.
Any ideas? I've followed all of Apple's setup guides with no luck.
