A ballpoint pen refill lasts longer than an ink cartridge because ballpoint pens use a thicker, oil-based ink that requires less frequent replacement compared to the liquid ink used in cartridges. The ballpoint pen's design also allows for more efficient ink usage as it only dispenses ink when the ballpoint is pressed onto the paper. In contrast, ink cartridges continuously release liquid ink, leading to quicker depletion. **

There could be several reasons why the printer is not printing after refilling the HP ink cartridge. One common issue is that the cartridge was not properly installed back into the printer.

Additionally, air bubbles may have formed in the cartridge during the refilling process, causing printing problems. It is recommended to double-check the installation, ensure compatibility, and try running a cleaning cycle to resolve the issue. **
