Re: Accessing Printer Firmware?
From the look of the article, this was a four month long project to exploit a security issue by a security researcher and was a lot harder than he initially thought! Unless you're comfortable with ARM assembly, electronics and have a lot of experience hacking devices already, you're realistically out of luck.
Of course, the article is also two years old and exploits a security hole that Canon said they'd provide a fix for quickly... no idea whether they did or not, but it makes the possibility of it less likely.
