New input: At first this printer worked well, but after a year it is nothing but trouble.To begin with, you can't print more than 4-5 pages before the "page grabber" will start to grab more than one sheet of paper at a time, and the text ends up going across both of them.Then there is the printer driver, which is also not up to par -- where is the manual two sided printing that has been in the classic Mac OS for all of these years?In short, this was my last HP printer. The jamming paper feed is too much for me to handle.
Solution:
Negative
