Hi, my Samsung all-in-one worked fine when connected (by usb not wireless) to my iMac, now retired. It's now connected (by usb not wireless) to my new MacBook Pro. It will print from an instruction from the MacBook, and copy/print documents, but, it won't scan. Well in fact it did twice, then every attempt from then on results in a failure. I attach the generated file, it's gobbledygook to me. I tried downloading new scanner driver but it didn't help. Can anyone help please?
