Slow Printing on Linux?

sciguy125 asks: "I switched to Linux a few months ago and the biggest problem that I've had is with my printer. I've got a Canon S520 and Red Hat 9. It prints painfully slow. If I want to print word documents that are more than 5 pages, it's faster to reboot into Windows and print from there. I've scoured the Internet and found that many people are having this problem, but nobody has a satisfactory solution. The most common suggestion is to get a faster computer, thinking that GhostScript is running slow. I'm fairly sure that isn't my problem because the processor is only at about half load when printing. I'm not exactly sure how wide spread this problem is, but I do know that there is at least a decent sized handful of people struggling with it. At first, I was considering dropping Linux because this printing problem is a serious issue with me, but now I just leave a good chunk of my printing until after 2am." Has anyone run into the problem before? What could make a print job spool at unusually slow rates to the printer?
