Can I schedule photos to be printed on a schedule ?

Qimage enables you to schedule how often it will automatically print its unclog pattern sheet. It is a single 8.5 x 11 plain paper print that uses a minimal amount of ink.  It can be scheduled to run as often as you feel it needs to be run.

If this is just to keep the ink flowing, so it doesn't need to be a perfect print or even a photo, then it can be any application that can print an image and can be automated/scripted on a schedule.

Photoshop can be scripted with JavaScript and VBScript (or AppleScript if it was a Mac), so maybe that’s a possibility.

I wonder if anyone has come up with a test image that uses about the same amount of each ink, so that some cartridges won’t run out faster than the others.

I take it these are prints you want as opposed to something simple like printing a test pattern once as day.

I don't think LrC has anyway to schedule printing itself. However, depending on the model of the Canon printer, it looks like you can use the Canon software to schedule the print.

I don't think Windows 10 has a print scheduler for jobs. You could print your images from LrC to file then use a 3rd party product to schedule the print. Note, I've never tried this. There are command line style methods to schedule print jobs if you Google it.

What model printer do you have? 

I would love to find this out too. As our inkjet printers last longer the more they get used. Probally can be done with a script or action?
