I have a Canon network printer which worked fine until yesterday, at the point I installed my new NAS. The printer will work over the network when the NAS is off or not connected but will not print at all when the NAS is switched on and is seen as a network drive by my iMac. Nas is a Buffalo Linkstation 2TB. Anyone help with this and provide a step by step (i.e. idiot's) guide to how I can fix it - it's pretty frustrating. Thanks in advance.
