1 or l

Who knew.....look carefully 1 or l .............if you're wondering what wrong here, I'll enlighten you. I've been unsuccessfully trying to load my "new" wireless printer to my computer......should be simple says my good friend, Kathy. I've had the thing for a month and each day that I've tried to load it......all kinds of things happen, none of which is the loading of the printer. It asked for a encryption key thingy.......excuse me if I had no idea what that was....LOL....anywhoooooo, I did locate a sheet of paper with all that info on it and immediately remembered the salesman saying that I should never lose that sheet of paper.............after having a glass of wine yesterday (large), I decided to give it one more try and "bingo" wouldn't you know but it loaded without a hitch. I really don't think this was "human" error (mine). I think it was the fact that alot of the FONTS are very confusing. The number "1" looks alot like the letter "l", don' you think?
