Summary: Adequate for less-demanding, simple graphics and text
Review: Canon is not the printer to get if you want high-quality graphics. Adequate for simple color graphics and text, but many other similar-priced products are far ahead in terms of graphics output quality.If you want photo-realistic color, go for an Epson (preferably the Epson 750) or Lexmark (Z51 is pretty good).

Summary: Sturdy little fellow
Review: I have absolutely loved this printer. It carried me through 3 years of school without constantly running to the computer lab to print drafts of papers. It handles a very high volume well. I have also found that by ordering off-brand ink tanks I can save a lot of money. Frankly, if you buy the Canon, HP or whatever manufacturer's ink, you're really being bilked out of a lot of money. I'm selling my printer because, like many of you have found out, it is not XP compatible. That's very clearly stated on the box. A manufacturer has no obligation to provide you with new drivers because you didn't read the printer information before upgradning your computer. If you're running an older OS and plan on doing so for a while this is a great little printer. It comes with my highest recommendation!

Summary: Falling Out Of Love
Review: I have owned my BJC5100 for just under 2 years. Maybe not even. Now that I have a new PC, I find that it is not supported by the Windows XP drivers. Canon, doesn't support it on these drivers either. I have tried a few tricks to get it to be recognized, and to print, but have only succeeded in becoming frustrated. Especially when it sits there like a...paperweight.
I love my little BJC5100. Unfortunately this love affair has to end. Fortunately, the printer will be gifted to a young relative who will be able to use it. This I find much better than sending it to a scrap heap.
As far as a review of the printer: well, you have to see it for yourself. It prints in brilliant, crisp colors, professional looking black type, and, newspaper quality grayscale. To own one IS to love one.

Summary: Pick something else
Review: I have the Canon 5000 and the 5100. Both are essentially the same printers, except for its parallel port protocol. If you have Win95 or Win98, then this is a decent printer. This series of printers' use a proprietary printing language, so getting third party support or moving this printer to another platform/OS is out. It does print on multiple paper formats, and is very good at printing photo grade images, but is very lousy at letter sized envelops. Not a very robust printer, especially when the print cartridges are hard to find and expensive. For the cost of two cartridges you can get another new Canon BJC-5100 printer. These printers are also "Win printers" BUT, they do support "HP Laserjet II" protocol. Its undocumented, but all laser printers and Jet Ink printers support this. So if you need to use it on a machine that it is not compatible on, then at least you can print in black. Look at HP products, they have better support and cartridges are a lot cheaper.

Summary: not the bargain you might think
Review: I needed to purchase a printer capable of accomodating 11x17 media for my architecture coursework and was initially attracted to the canon bjc5100 due to its price. I owned a canon printer previously and was well satisfied with it but this printer has done nothing but let me down. I found the manual feed-from-behind feature a tremendous annoyance as it requires a great deal of space. Also the printer does not automatically align any media fed from the rear so at least a third of my papers go through crooked despite profuse efforts to get them in straight. I also had a new problem occur recently. The printer decided to no longer recognize 11x17 media size and now every time I want to print at that size, I have to custom set it. Very annoying. Sure it's now going for around 99 bucks in all the stores, but keep in mind you're getting what you pay for.

Summary: Great printer for the money
Review: I own two of these machines and I have to admit I am a fan of Canon products. I also own their digital camera and copy machine. For the money it is hard to complain about this printer. It delivers nice crisp text at a very acceptable speed and can do some really nice things with digital images using their photo cartridge. If you buy cartridges for this machine at your neighborhood office supply, you could complain that it can be expensive to run. I personally used compatibles that I purchase on the internet and use a refill kit on the larger tank in holder two. This really makes the machine economical. The fact is that if you use a manufacturer's ink on any machine, you will pay a premium price. That's how they make their money. The larger format ability of this machine is also a bonus considering the low cost to initially acquire.

Summary: From Productive Printer to Paperweight
Review: I purchased my BJC 5100 about 2 years ago when I was looking for a large format printer (11x17) at a reasonable price. While the 5100 did meet those criteria, I have since had second thoughts about my purchase. What I like about the printer:
Good color and B&W print quality at a reasonable speed; minimal space required for a large format printer; attractive initial price.
What I don't like:
Ink cartridges are expensive (this is where printer makers make the real money) and don't last very long; if idle for more than a few minutes the thing goes through a loud and annoying boot cycle before it finally prints. For the most part this is a decent printer if you need larger format capability and don't want to cough up 3 to 4 times the money required for a competing product. But, be warned; if you are contemplating upgrading to the XP OS or already have it, don't buy this machine. Canon doesn't provide printer drivers for XP that support the 5100. This is extreeemely aggravating for those like me who need to upgrade or replace a computer but otherwise want to keep using their 5100...

Summary: sooo dissapointed---
Review: I recently bought this model from my mom who had used it maybe twice. My intention was to use it for papers and occasionally photos, not really caring about the quality, more of durability. However I bought it from her in August and now it is November and kaput! It keeps telling me I need ink, so I go and buy the ...cartridges and it still says i need ink. Done all troubleshooting and maintence possible, called canon, and they want 10 dollars to even talk to me. I'm soooo upset. I had heard about Canon's low quality, and now i know it. Printer lasted a little over a year 6 days to be exact (hmmm funny their warranty is only a year) with minimal to moderate usage and now i just want to throw it my window... I'm gonna go buy an Epson. If you know whats good for you, dont buy a canon!!!
