The Di LASER JET TONER CARTRIDGE 146A appears to be a specific model of toner cartridge for laser printers. However, there might be some confusion as the most common and well-known brand for laser toner cartridges is HP (Hewlett-Packard), which offers a toner cartridge named HP 146A for certain laser printers.

The HP 146A toner cartridge is designed for use with the following printer models:

• HP Color Laser 150a
• HP Color Laser 150nw
• HP Color Laser 250nw
• HP Color Laser 250dw

These printers typically use HP 146A toner cartridges, which come in color variants like Black (W1460A), Cyan (W1461A), Magenta (W1463A), and Yellow (W1462A). The toner cartridges are designed to provide high-quality prints for home or small office environments.

If you're specifically referring to a "Di" branded toner cartridge, it could be a third-party or generic brand compatible with the same printer models. Third-party toner cartridges are often cheaper alternatives to original brand products, but their quality and performance can vary.
