Worked the first time,fast, no problem or delays.
Down load went smooth on Windows 7
Cons
None that I found.
Summary
It was perfect. However, before the down load the printer made some grinding noise and I thought that it was broken. I have 2 other printers but just before dumping this one I tried an update and a new black toner cartridge, It worked! I am so happy to have saved a really good until from the dump.
