Is there some way the user can be informed of what format (i.e., color depth) is being used by the printer?

Therefore, I’m given reason to believe that my 16bit files get converted to 8bit before printing even though there is no warning, or any other indication, given that this is happening. At the same time I’m quite sure that I do NOT have the XPS Printer Driver installed. This includes Print Studio Pro occasionally and My Image Garden mostly. I’ve had NO problem printing my 16bit tiff files using the Canon supplied software. In addition, printing High Dynamic Range images (full 16-bit workflow) produces smoother gradations compared to printing 8-bits-per-channel images. When performing color adjustment in image editing software, adjusting in 16 bits per channel reduces degradation of image quality due to banding (gradient stepping). To print High Dynamic Range images, it is required to select the XPS printer driver. Since Print Studio Pro supports 16-bits-per-channel image data, you can receive the data as is from image editing software without degrading it, and print High Dynamic Range images (full 16-bit workflow).

The referenced new news, I just recently discovered, from the installed Canon user guide is the following (in italics):


Insofar as raw files offer greater depth of field for color than jpeg’s 8bit color depth I’ve been using 16bit tiff format for my master image files. One aspect of this has been developing the raw files from my Canon cameras myself. I have this photo printer because I’m after the best quality I can get. Recent research on print quality with my Canon Pixma Pro 100 caused me to come across some heretofore unknown information that appears as though it might be relevant.
