This two printer made with the same bases doesn't work on edgy.

This printer works good on breezy , almost good on dapper and now stop working on edgy tested on two machine .
I investigate that there is also a path problem because Cups web interface doesn't charge ppd file after installation. This printer has only a binary driver from seiko/epson.
Same here on my C1100 which worked fine in hoary, breezy and dapper
