This is great - I wish I'd done it earlier. After my printer was slow on a big job recently I decided to look for a memory upgrade. HP sells one for $143! This one is less than $10 including shipping and works perfectly. My printer is a LaserJet Wireless 1320 NW but the memory is listed for lots of others. Installing was simple. HP has great instructions with pictures on their web site. Step 1) turn it off and disconnect the power and cables. Step 2) open the print cartridge drawer. Step 3) Open the left side - it has clips at the top and bottom on the paper tray end and sort of swivels at the print cartridge end. Step 4) My machine only had its 16MB built in memory (leaving only 5MB for documents) so there was no DIMM to remove. Step 5) Turn the little cams that latch the DIMM in place to their open position. Step 6) Take the new DIMM out of its antistatic bag, holding it by the ends between your thumb and a finger. Touch your other hand to the metal of the printer to discharge, and...
I haven't had any problems with the memory card. It came packaged well. I installed it with the printer turned off. I turned the printer on and it found the additional memory with no problem. Unfortunately, I don't know if it sped things up. I don't notice a difference so far. But I'm glad I got the product and now the printer memory is fully populated.
I gave up 3 sticks of 32 meg for 1 stick of 128 meg. Best thing I did for the HP LJ 4100n. It works smoother now.
