It didn't take long to realize chinese is crap even if I got it for 40.00. Anyway I bought an APD 3000 but the manual doesn't say if you should leave it on like you do a computer or turn it off after each use. Yeah, I'm that green when it comes to plotters. I have learned a lot on signs 101, so thank you all for your past postings. By the way, the kids and I do it together, just making stickers and such for family and friends and really enjoy it. If we ever do charge for something it will be full price. I have definitely learned that.
