Currently I am printing with the (pluggin) software, firmware and driver which arrived with the printer last July. Firmware is v. 1.08. I am having only minor problems/issues. Everything is reasonably satisfactory. This a.m. Canon USA told me the following: the upgrades posted yesterday 2-13-07 includ a new driver, new firmware and an upgraded plugin for Photoshop. User can chose whilch of these upgrades to install, one or all. He said the Printer driver will not work with vista. He knew nothing about whether the firmware upgrade would work and said the new plugin should work fine. Since the firmware cannot be removed once installed, I am hesitant to use it with Vista until I know it will indeed work. Does anyone have any information bearing on this question??? If the original firmware works well with vista, will the new firmware do so as well??? Let me hear from you. Thanks.
