Frequently Asked Questions

What does page yield mean?

This means the expected number of printed pages an ink cartridge can produce. Because the number is only an estimate, the amount of prints you'll actually may vary. This is affected by several factors, including the type of paper you use, the settings of your HP Photosmart C4540, and how often you use the printer itself.

Why should I choose remanufactured ink cartridges?'s remanufactured ink cartridges, like the ones in our HP 74XL & 75XL Remanufactured High-Yield 3-Piece Combo Pack, are safe to use with your HP Photosmart C4540. They can also produce the same razor-sharp resolution and page yield found in their branded versions. But the main difference is their reasonable price tag, allowing you to print more without making a considerable dent in your budget.

Is there a difference between ink and toner cartridges?

Ink cartridges are used in inkjet printers, while toner cartridges are used in laser printers.
