Many printer manufacturers are still developing devices with complex cartridge refills. They incorporate microchips that interfere with the operation of the printer or make cartridge refilling impossible, for example by producing disposable cartridges. These cartridges are designed to wear out after a single use cycle and the cartridge bodies are constructed in one piece, making them impossible to disassemble without breakage and impossible to refill and reassemble properly after disassembly. In addition, inkjet cartridges often have a secret shelf life, after which the printer no longer recognises the cartridge, and after refilling the cartridge may stop working due to contact or ink level indicator failure.
For those who use the printer less frequently and have problems with ink drying, an inkjet printer may not be the right choice. When choosing a laser printer, particularly with regard to environmental considerations, it is worth giving preference to models whose cartridges can be easily and repeatedly reused after refilling. In addition, the environmentally responsible choice is to opt for larger capacity cartridges. They allow more pages to be printed and reduce the need for frequent cartridge changes.
