This one printer periodically has an issue where there are noticeable delays between pages. It seems to happen on larger documents and graphic intensive ones.
We have three of this model of printer here. But only one of them has this slowness problem. From their config pages they are almost completely identical. Except the slow one has the DLC/LLC protocal enabled.
I turned off the DLC/LLC protocal because we don't need it. We just use TCP/IP. But could DLC/LLC have caused a slowness in network printing?
