Answer: A - Corrupted drives is the most likely cause of garbled characters as output.

Key Takeaway: Corrupted drivers can result in garbled characters because the computer cannot properly translate the page images to the printer. A bad printer connection would likely result in no printing at all, as would incorrect permissions. Low memory is usually only an issue with large-sized graphic images, and usually slows down the printer before stopping it.
