If you want to save money and at the same time save the environment, refilling your own cartridges makes a lot of sense. However, this is something that the printer manufacturers comprehend and they have taken measures to ensure that you only use their highly expensive ink supplies. One way they do that is by updating the printer’s software via online updates. Once this is done, the printer will no longer recognize your cartridges.  

Firmware is the software that controls various computer parts including motherboards and printers. Users may come across many strange, remarkable and difficult to solve computer repair problems which resulted from the hardware compatibility issues caused by outdated system firmware. Printer manufacturers usually provide download link to update firmware software for motherboards, routers, printers and other devices available on their respective websites.  

As the printer gets older over time it is inevitable that the firmware will need to be changed or upgraded. Latest versions are occasionally released to concentrate on issues that have been revealed. To improve performance, to include the latest features to the printers or to fix existing hardware you need to upgrade your present software version. If your printer supports it, your firmware will be upgraded. For checking the availability, you can look at your manufacturer’s website.  

Once you have read the readme file for your printer model, you can either copy the printer firmware update directly to your printer by following a few commands or if your LaserJet printer is on a network, you can utilize tools that will take you through the upgrade process.
