we are trying to use iPrint with Windows x64 SP1 and a Develop Ineo +251 Printer.
I can upload the driver to the drivers store and assign it but afterwards I can not install the driver to the PC because the iPrint portal complains that there is no driver assigned.
And indeed: when I click on the info field of the printer in question it shows no association to the Windows 7 x64 driver.

Does anybody have an idea?
