For some older Epson large format products (Stylus Pro 4000, 7600, 9600 and 10600) and for the Stylus Photo 2100 printer, the only Mac OS X driver available is version 3.09.
This version is based on old driver architecture, and as a result has some limitations in comparison to the latest version 6.xx, which is based on CUPS technology and is available for most of the Epson large format and Pro Photo printers.
Version 3.09 can be installed on Mac OS X 10.5 (Leopard) on both Intel and PowerPC Macintosh, and on Mac OS X 10.6 (Snow Leopard) on Mac Intel only.
Limitations of driver version 3.09
The main limitation of driver 3.09 is that it's not a native 64-bit driver, so it can't be used with applications running in 64-bit mode. See the section Using the driver with 64-bit applications for more information.
Other limitations are: no 16-bit colour mode support, no "Auto rotate" feature for printing on roll paper, no "Photo Enhanced" color mode, and an old user interface (UI) design.
How to install the driver on Mac OS X10.6
To install this driver version on Mac OS X 10.6, follow the steps below:
Go to your local Epson Support web page, e.g. http://www.epson.co.uk/Support, select your product and then download the driver package (a .dmg file) from the Drivers & Software section.
Unpack the .dmg file, launch the installer and follow the on-screen instructions to complete the installation of the driver's resource files.
Add the printer's queue from System Preferences → Print & Fax:
If you are using a USB connection, you can add the printer directly from the Default window of the Add Printer menu. Select the desired printer from the list and press the Add button.
If you are using an Ethernet or Firewire connection, add the printer using the More Printers button located on the bottom of the Add Printer menu.
Select EPSON TCP/IP (for Ethernet connection) or EPSON FireWire, then select the printer in the list and press the Add button to create the printer's queue.
Using the driver with 64-bit applications
If you use applications running natively in 64-bit mode on Mac OS X 10.6, such as Safari and Preview, you may encounter the issues below when trying to print using your 3.09 driver.
You can't access driver menus from the application:
You receive error message "The bundle "PrintSetting" couldn't be loaded because it doesn't contain a version for the current architecture."
To resolve the issue, follow the steps below.
Locate the application (generally inside the Applications folder), and then open the application's information window by pressing the More info... button.
In the General menu of the information window, you can enable or disable 32-bit support. If Open in 32-bit mode is unchecked, it means that application is running in 64-bit mode.
To fix the issue, check Open in 32-bit mode and restart the application.
Within the application you will now be able to open the driver menus and print correctly.
