This Laser Printers give to us some advantages, like this :
1. Excellent printer for small office
We recently picked up one of the M451dn printers for use in our small business. We were using a Brother laser printer for most of our printing - and then switching to an Epson inkjet whenever we needed color.
Aside from having 2 printers, the main problems we were having were: the Brother printers in general tend to ruin envelopes and the Epson inkjets cost a fortune to run.
The main requirements we had for this printer included:
- Needed to be accessible through the network. Wireless doesn't matter at all - it just needs to be on the network.
- Good color capability
- Duplex printing - most of the documents we print are required by law to be duplex, and it's cheaper anyway since it saves paper
- Good envelope handling - As I already mentioned, I love Brother laser printers in general; but, they really do wrinkle up envelopes pretty badly
- Color printing needed to be less expensive than an inkjet - I know it's still more...
2. Great Printer - Insufficient Memory
I bought the HP M451dn printer after doing a bunch of research. However, none of the reviews explained that this printer only comes with 128mb of memory. Within a few days of operation one of our sales guys kept getting "out of memory" messages. The standard memory places (Crucial, Newegg etc) did not carry the extra 256mb memory modules. HP sells it for almost $600! I found what I needed at Parts-Quick.com for $13.99. The person I talked to was very helpful- a former HP person. I now have 384mb of memory and no problems. Why doesn't HP put enough memory in this one???
The memory you will need is CB423A HP 256MB DDR2 144-pin DIMM Code: EV_CB423A at Part-Quick - It was only after I did hours of research that I found Parts-Quick. The same module is available from Parts-Quick through Amazon but the Amazon description does NOT mention the HP M451dn as a model that this memory works with. See my similar review at the Amazon memory module page.

Great printer, but invasive software
I bought this printer a week ago, and so far I think highly of it, especially the duplex printing feature. However, I am very disappointed with HPs invasive software for detecting authentic cartridges. Google "HP print cartridge authentication" to learn more. They do a good job of selling the benefits, but after some additional searching, it's easy to see that a number of people have had unintended consequences--nothing earth shattering, but annoying time wasters nonetheless.
I have been clicking the "Decline" button (even though I buy HP Print cartridges), because I don't want big brother watching over me. If at some point I choose to take the risk and buy a third party cartridge, that's my business, not theirs. The real reason they are doing this is to force users to buy their expensive cartridges (that's where they really make their money).
I can overlook the sales pitch to install their monitoring program as long as they honor my decision to decline to...
