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 push the DIMM into its slot making sure it is aligned properly. You can tell which way up it should go because the gold terminals are grouped and the slots are grouped the same way. It may not seem to go in at first because when you push it in it moves the cams into closed position and that takes a tiny shove. Step 7) Close up the printer, plug it in, turn it on and you are all set for fast printing of large or complex documents.

Printer memory arrived promptly and was packaged well. Brand new, factory sealed anti-static bag. Within 5 minutes, my HP Laserjet 1320 was back up and running with 144MB of memory which is the maximum. After upgrade, my printer is notably faster in terms of time to print first page and the interval between printing pages.

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.

Works perfectly. Fit right in where it's supposed to go in the printer. When I restarted the printer it recognized that the memory was there, and now it prints faster and doesn't get hung up by a lack of available memory.

2 sticks 128MB for 2012 HP-4200 (32-bit on 64-bit WIN 7 - generic HP Universal PCL 6 driver). Quickly delivered, easily installed, HP stopped POSTing. A local service shop (Tulsa D-Tech) cleaned the chip slots to make good contact, cleaned the machine, perfect! Don't forget to reset settings mopier, storage auto (w/RAM drive), etc. 100pin 8xSAMSUNG K4S280832I-UC75 SDRAM 5.5ns 133MHz 3.3v. FYI, slot one factory chip is required - it has an 8MB flash firmware chip necessary for HP BIOS - install instructions are in your CD manual.

I got memory error after installing. Tried in another printer and got the same error. No problems with return & refund.

I had previously ordered from another seller but it did not fit correctly in the Dimm slot. I am very happy to report that this was shipped very fast and it fits perfectly and works as expected.
