Keep in mind, it wasn't too long ago when you had to purchased a $600+ printer to get the features of this one. Also, I do not like Brother printers. They are the generic brand of printers and have barely been supported by electronic retailers until recently.
This is my second Canon laser jet. The first was an all in one (print, copy, scan) MF1330. While it made flawless copies; it had no fax, could only connect to one PC through USB, and lacked the ADF (automatic document feeder). I have three PC's in my house. Two desktops and one laptop. The two desktops are running 64-bit Vista, and I have searched high and low for a modem that would work with a 64-bit OS. The only ones I found are not natively supported in Vista and cost $80+. The others were all external. If you don't know this, the Canon laser jets have a very fast first page out time. So when they say 23 pages per minute, it doesn't mean after a two minute warm up period. When you click print the PC (depending on speed) takes a few seconds plus to process before sending. With my computer, the entire print process took about 5 seconds before the page was being printed. Very nice! Imediately I noticed how quiet this printer is compared to my last canon and my Oki C5200ne color laser. Amazing for a laser jet. I hope they didn't sacrifice life expectancy or something else to get it.
I was a little disappointed. This printer didn't turn out to be everything I thought it would be, which is why I only gave it 4 stars. First of all, you must know Windows Fax & Scan does not work with this printer. That is the let down of the year to me, but it's not Canon's fault... not necessarily. Turns out WF&S only uses WIA scanning drivers and this printer uses TWAIN. Thanks Microsoft. The computer never directly communicates with the printer, so the faxing is treated like printing. As a result, the faxing portion of the software doesn't work with it either.
This printer DOES come with software for scanning. It's burried on the CD, and you must explore the CD to find it. I believe it's only for the PC, however.As the other poster said, I searched all over for the scanning software I thought I installed. Turns out it was just a driver. I own Adobe Photoshop and Acrobat, so it's not much of a concern for me. They are both TWAIN compatible by the way. One thing I don't like about this printer is the need to press the scan button prior to scanning. This is not very convenient for a network printer. It's even worse if you have a long way to go to get back to your PC. By the time you get there, the thing may have gone back into power saving mode.
Still with it's flaws, it's definately a great buy compared to similar products of the past (which were bulkier, louder, and more expensive). It does what it says it can do. Print (double sided at that), scan over the network, fax from your PC, and it's also voice line friendly! (No need for a dedicated fax line)It's a great buy.
