Summary: If you are running windows 7 on your computer, as I am, don't waste your money on this printer. I bought it because I needed a high volume dual tray printer for work, but it is NOT compatible with win 7, despite what the vendor or documentation may say. I did everything humanly possible to get this to work, including spending almost 2 hours on the phone with HP Tech support and they told me it just wouldn't work.
Summary: I just read some articles about the particle emission of the laser printer. This machine is one of the worst kind. You need to make sure that you also buy a laser printer filter if you really like this model!
Summary: I bought this printer because under the product description (#8 to be exact) says that it is a wireless printer with easy networking AND that it prints double-sided pages. I received the printer only to discover that it does neither. I have windows 7, and I figured out how to properly install the printer but there was no function for a wireless connection. I don not understand why this printer is listed as wireless, it is not!
Summary: I have purchased refurbished models that have lasted for years, but the HP 1320 is a piece of junk. The company has been of no help. I have called HP direct and they let me know that I purchased a printer that is broken.
Summary: I bought this printer because it offered duplex printing (printing on both sides of the page). This feature worked perfectly under Windows XP Pro and Vista, but it doesn't work under Windows 7. There are a number of complaints about this problem on HP's customer forum but so far the company has chosen to ignore them. If you are running Windows 7 or planning to in the future, it would be wise purchase another printer.
Summary: Does not work with new Photoshop. If you have CS3, this printer is obsolete. 2 hours on the phone with bad customer service and all they said was they dont work with the new systems. Many HP printers suffer the same incongruities. Not useful for the future.
Summary: The reason that the laser cartridge only last for 1000 sheet, is due to a business decision by HP to provide only "starter Cartridges" in most of their printers. They want you to spend four hundred dollars or more for their printers, but it pains them to provide you with a full cartridge.
