Dear Bah Dee,

Both are the same. It is HP 21 Black Ink Cartridge and the model number is written as HP 21 B where B stands for Black ink cartridge.

It is used for low volume heavy quality laser printing jobs and has 5ml of ink. It can be refilled. It can be used for Printers with model numbers- Deskjet 3910, 3930/v, 3940

Good Luck!

Both are same... It's comes in different types of packs, just because the 21 b is the newer pack easier to identify as the Black color ink so they added a black toned cover/pack and named it 21 B...
This will be more clear from the links below.

Hi friend,

HP21 and HP 21b are the Black Print Cartridges that were used by the consumers widely before 2-3 years.
But, due to close of production of HP 21 and HP 21b based printers, the sale of these cartridges also came down.
However, these cartridges are also available in the market for the consumers who are still having 21 and 21b based printers.
The main difference between these two cartridges is that the HP 21 cartridge has a low volume to hold black ink while 21b cartridge has 3 times more space than HP 21 cartridge.
Also, HP 21b is cheaper than HP 21 cartridge.
When, you purchase a printer say HP Deskjet 2235, then you will get HP 21 Cartridge with it.
And, both the cartridges 21 and 21b can be refilled easily.
