Backing up and restoring Speed Dial has always been a problem with Opera. The suppliers have never fully addressed this problem to my knowledge. To me it is the single biggest problem with using the browser.

My Opera browser will print one time after opening and then will not send another print to the printer queue. I have 2 printers wired to computer and another on wifi. Same thing with all 3 printers. There are no specific steps. Just open print and it fails.
