My name is XXXXX XXXXX X'd like to help you with your printer issue. As your Multifunction F50 is "much loved" you may not like what I'm going to tell you. This printer is officially not supported with OS 10.6, which is why you cannot find drivers for it.
Now having said that there is a possible workaround that may get this printer to function. Please bear in mind that this is not an official fix and therefore there is a very good possibility that this will not work at all, but it is worth a shot, here are the steps:
Hopefully this will do something for you, good luck. Let me know how it turns out and please don't forget to click the green "Accept Answer" button so that I can be paid for my service. Thanks.
No I actually mean the latest Mac driver. The PC driver will definitely not work for you. As for "Mount the disk image" it basically just means to double-click on the file so it opens a window with the disk contents. After you accept the question you can still add to this thread, that's how you'll let me know. Thanks
