4. Print head: .......This is the core component of a barcode printer and is responsible for printing images or text onto paper or labels. .......Different types of printheads (such as thermal, thermal transfer, etc.) use different technologies to generate images. .......What is a Thermal Print Head (TPH) in a Barcode Printer? .......A thermal print head houses a row of highly precise heating elements that can rapidly heat up. .......Upon receiving a command, the CPU precisely controls the heating mode, time, and temperature of the printhead’s heating elements. .......This orchestrated heat forms the desired barcode, graphics, and text on the label substrate. .......There are two main types of thermal print heads based on printing technology: .......Direct Thermal Print Heads: .......Utilize heating elements to activate thermal paper, causing it to discolor and form images or text. .......Do not require ribbons, offering lower printing costs. .......Produce lesser print quality compared to thermal transfer and are prone to fading. .......Thermal Transfer Print Heads: .......Utilize heating elements to melt the ink on a ribbon, transferring it to the label paper to form images or text. .......Require ribbons, resulting in higher printing costs. .......Produce superior print quality and durable labels. .......Support a wider range of label materials, including synthetic paper, silver paper, and cloth tags. |
