Need printer driver. Required print options are not available when using the latest published driver for this device which was produced prior to Intel Macs.

You don't need a "driver" as the printer supports PostScript. All you need is a "PostScript Printer Description" file to tell Apple's LaserWriter driver what special features the printer has. PPD files are cross-plarform compatible and will work under OSX as well as under OS9, Windows, Unix, etc.

OSX normally uses compressed PPD files, but the old uncompressed ones still work. The PowerPC PPD is perfectly suitable for your mac. Just put the file in Library > Printers > PPDs > Contents > Resources >en.lproj and the Mac should find it when you Add the printer. It it doesn't, just browse to it when you install the printer.

If you don't have the PPD, download the Win2K PPD from http://tinyurl.com/6a65a8
There is also a Splash PCI 6 PPD for OSX on http://tinyurl.com/68983b but I would start with the Win2K one.

Thanks for your reply. The suggested ppds are what we have been running all along.  The Win2K gave the same error as the OS-x Splash PCI ppd.  Additional info that might help:
-The PPD works on powerpc mac (running Tiger), but not on a Intel Mac (running Tiger OR  Leopard)
Current PPD location:
MacintoshHD/Library/Printers/PPDs/Contents/Resources/en.lproj/SPREGA50.PPD

See attached screen shots of errors. This is what is peculiar when using an Intel mac. When choosing bypass tray (which is needed for heavyweight paper) an error is displayed that say you can't do that and it defaults back to normal paper....and visa versa, if you select heavyweight paper, the tray setting defaults back to autoselect.

regarding: "...is not available when tray selection is set to Tray 3..."
Note that the error message is not accurate because it refers to Tray 3, even though tray 3 was not even selected in the first place -- Bypass tray is what was selected.  

This problem only happens on Intel-based macs
Thanks for your help.

It sounds as if there are some logic errors in the PPD file, but it's weird that it only happens on Intel machines. That seems to imply there is a problem in the LaserWriter driver itself. Maybe you should check if there is an upgrade available from Apple.

PPD files are text files that tell the PostScript (LaserWriter) driver how to handle a specific printer. Being text files they work on any platform. The PPD file contains a section called "UIConstraints" that details which features work together and which won't. In your case it looks as if the LaserWriter driver misinterprets it on the Intel Mac.

I don't find any  LaserWriter sofware available for OS-X. Any references that I do find are for laserwriter hardware (printers) or for OS 9 or earlier. Perhaps the LaserWriter Driver you're referring to is called something else in OS-X. A "find" on my computer also does not yeild any results.
Any ideas?
Thanks.

The LaserWriter driver is the PostScript printer driver that is part of OSX. That driver works with every single PostScript printer on the market. The PPD file tells the driver what specific features (tray, paper size, duplexing, etc) are supported by a particular printer.

Adobe used to supply an alternative PostScript driver (which used the same PPD files) for OS9 but I don't think that is available for OSX - at least I could not find it on Adobe's website. And you're right, there are no upgrades on Apples website either. You may have to wait for the next release of OSX to see if there is a fix.
