They smear if you touch them too soon. They smear if you use a highlighter. Even on things I print for my records, such as a client email with some tax info, I like to highlight the tax info buried in a rambling email. Smear. If I look at it days later, can't read the smeary numbers. Want to highlight something FOR a client; don't even think about it.
I do have an inkjet all-in-one for my personal use, but won't use it for any biz printing at all. Even then, won't print out church bulletin when I'm a liturgical assistant, because I like to highlight what I lead.
