Macintoshes can not print .psd files using Adobe Photoshop CS3 to our Dell 3115 Printer via the Windows 2003 Print Server. Word and other types of documents print fine from the Mac to the 2003 print spooler. Trying to print .psd files to the Dell 3115 from the print server results in huge file sizes in the queue. Created an IP Printer on the mac that connects directly to the Printers IP address and that works. It seems like my print spooler does not know how to handle the .psd files even though I do have the Postscript 3115 driver installed. What am I missing on my 2003 Server? The one strange thing I notice is that my print server shows the port the printer is connected to as NtwkPort00 instead of the actual tcp/ip port number I am used to seeing.
