If only not the matter of the drivers would have ... As noted several reviewers have for this printer (as well as for the vast majority of Canon photo printer ...) no Windows 8 (.1) driver available - for a printer the mind is still sold! When asked about this pushes the Canon Support the buck toward Microsoft because the WHQL certification for Windows 8 (.1) can not meet new requirements would, therefore, the printer for technical reasons.
Whether this argument is true 100%, or more likely to be regarded as an excuse is because you just do not want to bodybuilding and only sign the drivers I can not judge. I was certainly far the view that the printer driver does not necessarily need the WHQL certification to be accepted by the operating system, as long as the driver has a valid Authenticode Level 3 Signature features (and in generating the necessary for the .inf files * .cat files just the operating system must be specified with - so if the drivers with the tools of the older (pre-Windows-8) Windows DDK was signed then accept Windows 8 (.1) the signature just not what but when by simply changing a command line parameter Change signing could - as long as MS does not throw the driver model to the winds ...). But perhaps what escapes me since ...
In fact, there's a way around it by Windows configured so that unsigned drivers are accepted (is meant for developers to debug drivers) - but that it can not be it, that I turn a meaningful and established security mechanism in the system just because of Manufacturer's ass does not get high.
Somewhere under the line, I would tolerate such Gezicke at any Billigheimer - for Canon I find it quite embarrassing, so that will have been my last peripheral device for this manufacturer.
