I had the same problem when installing my Epson R300 onto my new iMac (Snow Leopard). The first install used the newest online driver from Epson. The printer symptoms were exactly like yours. Then I installed the Apple driver updates. It was seamless and now the printer settings can be accessed. Perhaps if you uninstalled (read about that on the Epson site first) and then downloaded the new factory driver, followed by the Apple update which will further update files, you might have some luck. Just a guess on my part. Best wishes.

You can find useful information on site? http://www.epson.com/cgi-bin/Store/support/SupportSnowLeopard.jsp Mac OS X Snow Leopard Support Contact Support Welcome to Mac OS X Snow Leopard v10.6 support for Epson products. Here you can find out how to get drivers and other Epson software for your Epson product that work with Mac OS X Snow Leopard v10.6.
Check your Epson product CD to see if it already contains Macintosh OS X 10.6 drivers. If the CD indicates support for Macintosh OS X 10.6, follow the instructions that came with your Epson product to install your drivers and other software.
If your Epson CD does not indicate support for OS X 10.6, DO NOT INSERT YOUR EPSON PRODUCT SOFTWARE CD IN YOUR SNOW LEOPARD COMPUTER. Follow the step-by-step instructions below to obtain the latest software and utilities for your Epson product as they may be needed for this new operating system.
Good Luck.

i downloaded an updated driver for the rx595. it's all good.

that is a common problem with the new leopard software by now I think they have fix that so try to download the latest drivers if not check your printer settings

You definitely need to use the updated driver for Intel Macs.

I was also having problems with my Epson scanner on my iMac. I read that the best way to solve Epson's problems is to (1) uninstall all Epson software from your HD, and (2) download the appropriate drivers from Epson and install them.

Note: The Epson R1800 has two drivers: the most recent is an update. So, you must first download and install the Printer Driver v6.12. When that's done, then download and install Printer Driver Update v1.02.

I did that and I still got dark prints. Then I got an inspiration. In the Print dialogue box, I changed my Printer Profile to the paper I was using, Epson Premium Luster Photo Paper, instead of using sRGB and/or Adobe RGB. Specifically, I used SPR1800 PrmLstr PhotoRPM.icc. The next test print was virtually spot on to what was displayed on the screen. I am now a VERY happy camper.

Please pass this info onto anyone else who can use it.

need to check for an update - go first to support.epson.com

second place to look for updates is from the software manufacturer (yes it says EPSON Smart Panel but it is a bundled application)

I had the exact same problem with the endless blank pages "printing" out.  I have a MacBook Air with OSX 10.5.6.
Before I got a chance to try and delete and reinstall all the drivers all over again, my phone call was answered by a very helpful lady from Epson's support line US: 562-276-4382.                           
Here's how easy it was to fix: Go into Apple System Preferences, click Printer & Fax. HOLD CONTROL while clicking on the printer on the left side of the screen.  When you HOLD CONTROL, it allows you to choose the option to "Reset Printers".  
Click "Reset Printers", and you will see them all disappear.  Simply plug in your CX8400 and click the plus button to add new printer.  It will search for the driver for you if you have an internet connection.  It worked for me on the first try and took only about 2 minutes total!!!!
I'd wasted so much time installing drivers and screwing with the printer before this.  Save your time for things that make you happy!  Share help when you can!

Reinstall everything: leopard, driver?
