was surprised to see that Qimage absolutely wants to print with matte ink, MK.
I thought plain paper required PK, but the printer manual says either one.
That is not Qimage doing that. It is your driver and paper selection.
I turned off the Qimage AI and the driver will select MATTE black when you select Plain Bright paper. See attached setting from your driver.
When the driver sets the ink to Photo Black, the paper selection changes in your driver to UNLISTED 348. Thenit works with Photo Black ink.
