Here is the history of my issues with my iMac. I have had it for several years, using a HP Officejet Pro 8600 with no problems. Usage is mostly music, photos, and a few uses of Office for Mac, particularly Excel and Word. About 6 weeks ago I went to print something and the printer never responded. Upon checking, the computer said the printer was idle and the computer was waiting to the printer to connect. It was connected but for some reason the communication between the two was lost. I knew it was not a printer problem because I could connect it to my laptop and it worked fine. I could never get an appointment at an apple store so I went to an authorized apple repair dealer, and they could never resolve the issue, but thought they may have deleted a couple of suspicious files. So they restored the system. Fine, so it printed but I lost GarageBand, Office for Mac and all the music, photos, and documents I had.
So I proceeded to back it up from the back up disc I have. Everything was restored, but it would not print again. My assumption was that something that had been backed up on my backup disc was reloaded on the computer, preventing it from recognizing the readiness of my printer. So I took it back to the dealer (still no possibility of getting in to see a "genius") and they restored it again. I am back to square one and want to be able to print from this computer, so I want to be selective on what is downloaded from my backup.
Does this explain this better?
