If you are looking for HP laserjet toner, make sure to know exactly what kind of printer you are looking to print on. Without this crucial information, you may be totally lost at sea. There are simply hundreds of different printers and models that without this combination of numbers and letters to direct you in your quest, you might as well just go home, seriously. I’ve been to the office supply store searching for printer ink on many occasions, only to think I had the proper combination of letters and numbers, make and model, size and colors, all straightened out in my head. But once you get in front of a thousand other disparate combinations of letters and numbers, all very similar but incredibly different, it is easy to see how one could get lost in all of that. I sure did, and I still do if I do not slow down and take my own advice.
This is where the old-fashioned pen and paper come in hand. Write it down. Whatever printer you are using and need to replace the ink with, write down the make and model, and also the color ink you need. I know, I know. That totally sounds like overkill, but this will save you a lot of pain and problems, because a lot of printers these days have different cartridges dedicated to certain colors, i.e., cyan, magenta, yellow, black (CMYK).
So if you take my advice and slow down for a moment, you will be thankful. Because that one day you are in a hurry and don’t take the time to write it down, you will end up wasting your time making the extra trip either to make sure or to return the incorrect purchase. Do not let your time go to waste like that.
