I used to wait and print one page at a time. Now I can just send 5m files, and it prints quickly because of the memory upgrade.

My HP printer stopped working after about 7 years of use. It kept telling me that it is out of memory. I called HP tech support, did all the trouble shooting, nothing work. I thought instead of spending hundreds of dollars on a new printer, I will risk a few dollars and try this out. It worked and it was very easy to install. The printer is working better and faster then when I first bought it. I hope to get a few more good years out of the printer.

This made a huge difference in my HP Laserjet Pro 300 printer. Now I don't get those cancelled printing jobs because of low memory.
