Single-sided printers vary from basic entry-level models to powerful high-end machines. Single-sided printers can be utilized to print both sides of an ID card, but the process isn’t as streamlined as it is when using an ID printer designed to print on both sides. It’s best to use dual-sided printers for high-volume batches of double-sided cards and for card programs that require personalized information on both sides of cards. A variety of features is available in single-sided printers, including full color printing, card encoding and laminating.
