Printing

I usually know what I'm doing, but it seems I can't access the extended options of my printer's drivers over my network.

When I plug my printer into my macbook using a USB cable, I get all the options that my printer provides, such as quality control and colorsync.

However, accessing the printer through 'printer sharing' when it's connected to my iMac (PPC) gives me no such options. Even though printing directly from the iMac does give me these options.

Both have the drivers installed, downloaded from the official EPSON site, but not matter how many different ways I add the printer from Printer Setup Utility I can never access these options.

It prints using the standard controls the whole time, but for photo's I have to move close to the printer. which is very annoying. I would be grateful if anybody can give me advice.
