My dad’s big fancy Cannon photo printer has caused him nothing but grief. He swears up and down he needs to be able to print large-format full color photographs, but I have never seen him do so. What I have seen is his black cartridge dry out between uses and fail when he needs to print a form.
My wife is occasionally frustrated by our inability to print color, but I am more than happy to drive to Walgreens or my companies office to print a color item once every couple months. An inkjets ink would’ve dried between prints.
I recently used an online photo printing service for the first time.
It was awesome.
To persuade your dad, maybe send him a print (directly from some service).
