I got problems when I want to print documents in PhotoShop CS4 (Mac version) on a printer defined with iPrint.

I used iPrint client for Mac 4.40.
OS X is up to date : Leopard 10.5.7
PhotoShop CS4 was updated : 11.0.1

When I try to print in Photoshop CS4, I see the error message, "Before you can perform printer-related tasks such as page setup or printing a document, you need to install a printer."

This errors occurs only with this application. But PhotoShop not just the problem because if I print on the same printer defined in System Preferences\Fax & Printers utility; the impression worked fine. I defined it with printer's DNS name and IPP protocol.

So, there's a trouble between PhotoShop CS4 and iPrint client.

Is there anybody that can help me ?

Thanks a lot for your collaboration.
