My Canon Pixma Pro-100 is printing mirrored, with left and right reversed. I see now that it must have started some weeks ago (I don't print too often.) Before that it was normal. I've checked page set-up and reverse image is not checked, and print to JPEG to desktop is correct. Has anyone here seen this before and know how to fix? Printing from Lightroom CC.
Have you recently done an operating system upgrade to a newer version? If so, it may be that you need a new Canon printer driver.
