I am using a 740 and it works very well. To set a 740 up, you need to go to http://lcewww.et.tudelft.nl/~haver/linux/epson.html and download the 'epson740.tar.gz.' file provided on the page. After untarring, uncompressing the file, you need to transfer the 740 related files to the /usr/lib/ghostscript/ and the printer database file to /usr/share/printtool/printerdb after renaming the file as per directions on the webpage (keeping in mind that the directions are for Red Hat systems). Then use printtool as per the directions on the webpage to set up the 740.
The results have been excellent. kometboy
