It is 5 months since I upgraded to Snow Leopard - from that day forward I have been unable to use my Canon ir2022i printer/photo copier for network printing. I can link to a colleague's computer and print through them, but the capability is not available with my own computer and if the colleague's not in ... well too bad! I am experiencing difficulties with all the printers in my office - so it is not an isolated incident (I'm currently having an interesting relationship with an HP Laserjet 1022 which will only print odd numbered pages). I called Canon again today who took no responsibility (Please someone listen - do not buy Canon Photocopiers with network printing enabled) - Canon say its MACs fault. "The printer works" they said, "its the OS that doesn't work". What is MAC doing to resolve what seems to be a pretty widespread printing issue with OS 10.6, and what are they doing to work with partners such as Canon to ensure updates are provided quickly. By the time this is resolved both the OS and the photocopier will be old news.
