I had a HP and was very happy with it over the years but since my new computer there are no drivers for the update so it is time to go. Any comments on HP units???
After serious investigation (I'm a analytical chemist, I research EVERYTHING), my first printer was a HP Deskjet 712C that I purchased in 1998. I loved the quailty and the durability. I do quite a bit of graphic work and photoshopping. It wasn't the fastest prinbter, but I was happy with it. It was the only printer I owned, and I didn't get rid of it until June of 2008. Can't argue over a printer that will last you a decade.
For a replacement, I invested a little more money and purchased a HP Deskjet 6980. The quality is great. The speed is sufficient, and it's WIRELESS. Installation was a little more involved than I would have liked, but you can configure the wireless feature either through your wireless router (as I did) or through the built in wireless.
We print from three laptops and one wired desktop, and have had no problems.
One note: If you run Vista, there is sometimes a problem printing from Vista to certain HP printers. There may be fixes out there, but as I run XP (mainly because Vista is crap).
Do NOT buy an ALL in one printer (one that prints, scans, faxes, walks the dog and prepares Decaf Lattes). They may do everything, but they do none of them well. If you want a scanner, buy a flatbed. If you want a fax, spend $20 on a stand alone.
I'd only use Lexmark if you are making massive amounts of four-color labels. They're great forlabels, logos and such, but nothing with photographic quality. They are expensive and require a lot of work.
Hope this helps.
