I bought a new iP7250 yesterday to replace my previous Canon printer that keeled over and died. The reason I bought it is primarily to print on DVD, as I have another Canon printer for normal printing.
I had major problems getting the new one running on 3 Macs using USB connection, but eventually printed 6 DVDs; brilliant results.
This morning, all the printer will print is blank sheets/DVDs, though I changed nothing overnight.
Installing from the CD that came with the printer gives me a warning that Sierra isn't supported and there may be problems, so I downloaded the Sierra driver from the Canon website. Today that driver doesn't work.
I used Easy-Photoprint EX successfully yesterday but while it goes through the process today - just firing blanks.
I'm a huge Canon fan (cameras etc) but I really can't figure why it worked, and now it doesn't. Canon Support doesn't have a clue.
Is there anyone here who can suggest anything?
I'm guessing it is a driver issue, though when it worked yesterday it was on a MacBook using a Beta of MacOS 10.12.15. It won't work on 10.12.14 or the Beta today.
