I have not installed the Toner Cartridge let. I knew that the one that I had was running low to keep printing. It's good to have a backup when you need to replace the worn out one.
I have been ordering this toner cartridge since I purchased my printer more than 7 years ago. I like it because I print banking , budget, and online purchase information from my computer and the cartridge lasts a long time.
I have a wonderful hp black and white laser printer that finally ran out of toner. It was simple to find the cartridge using the hp smart app which knew exactly what i needed. It was very easy for purchase. The hp printers and the hp smart app are fabulous.
