On your computer, in the Windows Notification Area (bottom-right corner of your Windows desktop), right-click the printer icon. In the printer menu, select the Properties or Preferences option. In the printer settings window, the ink or toner levels are displayed for the currently-installed cartridge(s).
To Determine Manufacture Date Based on Serial Number: The 1st three numbers of your serial number will always provide your manufacture date. The 1st number is the YEAR of manufacture; the 2nd & 3rd numbers indicate the MONTH of manufacture.
Most shelf-stable foods are safe indefinitely. In fact, canned goods will last for years, as long as the can itself is in good condition (no rust, dents, or swelling). Packaged foods (cereal, pasta, cookies) will be safe past the `best by` date, although they may eventually become stale or develop an off flavor.
For toner cartridges, there is no expiry date. Toner may degrade over time and the print results may not be as good as they were, but toner does not expire. If an ink cartridge is unopened or not used, so long as it`s kept away from humid environments, it should last at least 2 years.
The short answer is YES. Printer ink expires. Ink cartridges can usually last two or three years if properly packaged and stored. But in a standard case, they will eventually dry out and become useless after this period.
Benefits of using toner and laser printers

Furthermore, toner does not dry up in the same way that printer inks do if you don`t print so often, saving time and money.

The standard cartridge is your run-of-the-mill cost savings cartridge. It typically gives you about 10,000–12,000 pages.
A high yield cartridge holds more ink than the standard cartridge and as a result, offers considerably more prints. High yield cartridges are more expensive but are often worth the extra money for print heavy consumers.
Toner is a very fine powder consisting of 5 to 30 μm particles. Due to the very small particle size, the powder is flowable and behaves like a liquid. Toner is composed of synthetic resin, pigments, magnetizable metal oxides and various auxiliary substances.
Printer companies price their devices very competitively, in order to entice customers into buying their products. This leads to a nearly microscopic markup, if any, on most printers. And those devices still require investment, time, engineering and resources in order to produce.
