UPDATE: The new 'new' lol (!) Leopard driver has finally been released and now fully working. Here is the link to the driver [LINK] (driver 3500-4000 series) For 1480 printer, kdkoto has posted a link to new experimental driver as a temporary fix. You can see that post here. ----------------------------- Original thread contents below: I have searched and there are tons of Lexmark threads but none that's specific to my problem or the new Leopard driver so here we go (sorry long post but trying to explain everything).... I posted on the Apple discussion forums but people are telling me to remove the PDE folder which doesn't work for me and besides its a new Leopard specific driver now it really should work and now it's driving me crazy. What I've done is when I first got my MBP it came with Tiger. I installed my printer (Lexmark X4580) absolutely fine. It's a Wifi printer and I can scan and print wirelessly... it was great. I upgraded to Leopard. Printer disappeared from the printer list. Tried to install it, drivers installed OK, the printer was unable to add to the printer list, pls try again, I did, same thing and repeat and so on etc. I had upgraded to Leopard by doing the 'upgrade' way so I rolled back to Tiger and did put the printer on again. It went on absolutely fine again. So I upgraded to Leopard doing the Archive and Install method. After that was done, same thing. Printer was gone from the list so I tried again with the driver (bearing in mind this was the Tiger driver). Didn't work so I started googling the net. People were saying to try and add it manually I did that via IP address and pointing to the drivers but it would just crash instantly so I gave up for a while and waited for the 'Leopard driver' to come out. So I waited and it came out on the 21st. Tried it and got the EXACT same error. Here are screencaps of the errors.. So I went back to the thread posting it doesn't work. Tried to add it while plugged into the USB. It kind of recognised but crashed again. They told me to remove the jplugin (or something) file. Did that but still crashed with next file error, so they told me to remove the PDE folder but said if I do that it will work plugged into USB but limited functionality. Thing is, I don't want that I want FULL functionality. I paid for the printer and they have released a Leopard driver. I can't understand why it won't work. I'm getting really cheesed off (understatement) with it but I cannot afford to buy another printer right now. Ugh. Anyone out there that has any help that will restore full functionality?
