It depends on how much information you need to put on your cards. For example, if you will only be placing the cardholder's photo and name on your cards, the single-sided ZXP Series 3 may be ideal for you. However, if you need to place more information on your cards, we recommend the dual-sided ZXP Series 3 so that you can print to both sides of the card in one, simple process.
Many customers ask if it is possible to print on both sides of the card with a single-sided printer by manually flipping the cards and sending them back through the printer. While technically it is possible, it's not recommended. Printing on both sides of the card with a single-sided ZXP Series 3 printer will expose the printhead to dust, debris, and oil from your fingertips, which can cause expensive printhead damage. Plus, damage to a printhead from non-standard use will void the warranty coverage, costing you more in the long run.
If you will be creating ID cards with limited cardholder information, choose the single-sided Zebra ZXP Series 3.
If you will be printing more information on your cards and want the ability to print on both sides of the card, choose the dual-sided Zebra ZXP Series 3.
