I need help with the Pixma Pro 100 printer and hoping people use it here. The manual and Canon support are no help at all. I got it all set up and did the alignment head test without a problem. I just can't print anything after that. I have tried everything and have the right photo settings. I click print and it just says printing and the power button flashes. Nothing after that and I have waited 20+ mins. The test printed in less than 5. I am using pro luster paper if that makes a difference and using the rear tray and not the feed tray. I have tried using the pro garden app and just Macs preview and nothing. No error code or anything, just says printing.
