Where could I find a printer to print customized mouse-mats?

Thanks,

Adam

Well i'm not even sure if that is possible, the mouse mat would have to be reasonably thick and i can't think of any printer than can do that. You could print the design off and then iron it on like you do with T Shirts but it might look a tad unprofessional and fall apart easily. If you're doing it to sell then it might be an idea to look for a company that can do it for you, the finished product would be far better and you can still make a decent profit.

Vinyl Stickers?

Head over to your local craft store, they sell special paper to print on specifically if you have ink or laser printer.
