Query: Fast, but not worth it

I wish I'd read the reviews before buying this printer. It's fast and the print quality is fine, but it has the paper-curling problem that other reviews mention. It doesn't matter too much with one or two pages, but for larger documents it can be a problem. Also, the toner ran out after just a month, which I wasn't expecting. When I bought this printer, I thought I would get an updated version of the reliable 1440, so I was disappointed to find out that the 2040 is a whole different creature. I wouldn't buy this printer again.
