I don't think so. Canon provides the XPS driver, but Windows doesn't seem to support 16 bit printing. I have used both the regular driver and the XPS driver, and I haven't been able to detect any difference in the resulting prints.
Are you printing with Lightroom ? If yes, then it probably means LIghtroom for Windows does not support 16 bits even using the XPS driver...and thsi is my question
My understanding is Windows supports 16 bits via the XPS driver.
I have printed from Lightroom, from Photoshop, from Print Studio Pro, and from Qimage. And the result is always the same. All of the programs will utilize the XPS driver, but the general consensus I have seen on other forums is that Windows itself does not support 16-bit printing. As I mentioned previously, I have compared prints done with both printer drivers and have not been able to see any difference in the resulting prints.
