I purchased a Samsung SCX-3405W a few months back. It says its mac compatible on the box and worked fine up until I changed the toner cartridge. The printer says the new cartridge is incompatible - I investigated with the toner manufacturer/forums and was recommended to update the firmware - Unfortunately the Samsung website only offers a windows compatible firmware update. After emailing Samsung Hong Kong (my location), they returned a message telling me I need a windows computer to update the firmware Hong Kong has no consumer laws so there is probably not much avenue for complaint. I notice that the same firmware update is on the Samsung US site, anyone else encountered this issue? Have suggestions?
