I trying to help 3 people with the identical issue. One of them being myself. Printing large pdf files and also some web sites is painfully slow to various brand and model laser printers. When I try printing from (ugh) windows7 it is fast. The laser printer LED shows data being spooled to it and lpstat -t shows the percentage of the job being spooled (this is slow). When it gets to 100% then the printer does come on and print as expected. If I choose to print to an INK Jet color printer then that is fast. It is only Laser printers the slow behavior. I have tried with various versions of Ubuntu including 11.04 all with the same results. I am not looking for speculation as to how to resolve this but more from others that have seen this issue and have found a solution. Cheers, Bob
