Printheads: What Do We Need to Know Before Buying a Printer?


Investing in a new printer involves careful consideration of various factors to ensure that the chosen device meets the specific needs of your business or creative projects. One critical component that directly influences print quality and performance is the printhead. Before making a purchase decision, it’s essential to ask pertinent questions about printheads to ensure you select a printer that aligns with your requirements.

1. What Type of Printhead Technology Does the Printer Use?

Understanding the printhead technology is crucial. There are two primary types: thermal and piezoelectric. Thermal printheads use heat to expel ink, while piezoelectric printheads use electrically charged crystals. Each technology has its advantages and disadvantages, so it’s important to choose the one that best suits your intended application.

2. How Many Nozzles Does the Printhead Have?

The number of nozzles on a printhead affects printing speed and resolution. A higher nozzle count often results in finer details and faster printing. Knowing the nozzle count provides insight into the printer’s capabilities and its ability to handle intricate graphics or detailed images.

3. What is the Print Resolution of the Printhead?

Print resolution is measured in dots per inch (DPI), indicating the level of detail a printer can achieve. Ask about the native resolution of the printhead to understand the printer’s ability to produce sharp and clear prints. Keep in mind that higher resolution doesn’t always guarantee better quality, as factors like ink quality and media type also play a role.

4. Is the Printhead User-Replaceable?

Some printers have user-replaceable printheads, while others require professional intervention. Knowing whether you can replace the printhead yourself can impact maintenance costs and downtime. User-replaceable printheads offer convenience, especially in busy printing environments.

5. What Types of Inks Are Compatible with the Printhead?

Printheads are designed to work with specific ink formulations. Ensure compatibility with the inks you intend to use, as using incompatible inks can lead to performance issues and potential damage to the printhead.

6. What is the Quantity of Picoliter Drop? Is Droplet Capability Variable?

The quality of the print is higher when the drips are smaller. Smaller drop sizes, however, may cause a printhead system’s speed to decrease. Printheads with larger drop sizes also tend to print faster, but they do not provide the same print quality.

7. Is There a Particular Head for Varnish or White Ink? Or Equal to the CMYK Model?

Some printers offer a “white ink drop size favorable head” specifically for the white ink since it might perform better with a larger nozzle. The same head is used by other printers for all colors. To find out which head is appropriate for varnish, it is best to speak with an experienced printer operator and printer designer. Working with varnish is more difficult than working with ink. For similar reasons, make sure the recirculation mechanism in your white ink is in place; if not, the white particles will settle and clog the nozzles.

8. Does the Printer Have Automatic Printhead Maintenance Features?

Printhead maintenance is crucial for consistent performance. Inquire about automatic maintenance features such as cleaning cycles and nozzle checks. Printers with intelligent maintenance systems can reduce the risk of clogs and ensure reliable printing over time.

9. What is the Printhead’s Duty Cycle?

The duty cycle indicates the number of pages a printer can handle per month without experiencing performance issues. Understanding the duty cycle ensures that the printer can meet your specific volume requirements and operate efficiently under your intended workload.

10. Are There Warranty and Support Options for the Printhead?

Printheads are essential and often expensive components. Ensure that the printer comes with a warranty that covers the printhead. Additionally, inquire about available support options and the manufacturer’s reputation for customer service.


Asking the right questions about printheads before buying a printer is crucial for making an informed decision. By understanding the printhead technology, resolution, maintenance features, and compatibility, you can choose a printer that not only meets your current needs but also provides long-term reliability and performance for your printing projects. Taking the time to evaluate these aspects ensures that your investment aligns with your expectations and contributes to the success of your printing endeavors.
