How does the cheap printer ink (or toner) compare to the original printer ink (or toner)? Is the quality worse?
 
You may not be able to compare print quality differences, but you can determine the huge difference in price and environmental protection.
 
First, let's discuss the quality of both. It is undeniable that the quality of the original ink cartridge, the original ink cartridge and the brand printer are perfectly matched, the quality is relatively stable, and the ink cartridge mold has high precision. However, this does not mean that the quality of compatible ink cartridges is not good. Compatible toner cartridges are as good as original toner cartridges but at a more affordable price, but you may not have found them yet. There are many high quality stores that sell compatible ink cartridges. They strictly follow the standards of original ink cartridges and produce compatible ink cartridges. They also have their own brand, technical support and perfect after-sales service.
 
As others have said, "cheap" may not be the best description. Cheap ink and toner are better expressions, even very subjective. First check to see if the vendor you selected is just refilling the existing cartridge with new ink/toner, or re-manufacturing the cartridge. In inkesale, they do the latter. Although refilling and emptying the ink cartridges with ink or toner may work (and usually at least a few previous additions), there will eventually be other parts of the cartridge that are subject to wear. So make sure they are rebuilding the toner cartridge and replacing all possible (and indeed) worn parts. Be sure to install a new chip (such as TN760 to ensure that your "newbie" cartridges are not "expired" or unavailable.
