Problems printing with OS X Lion and 4.1.18 ***SOLVED***

I've read this threat with interest, as I too lost the ability to print on my network when I upgraded to Lion. I've followed the suggestions offered here, but it took me a long while to work out what the username and password settings for my smb connection were... in the end I realised it was Guest and password (or, presumably more correctly, any string for password). Got there in the end - but it seems strange that there's no fixed solution to this, leading users to get into more detailed configuration settings... Anyway, thanks to all who have offered solutions here. :)
