: Visit the Official Order Page to buy a single or multi-user license. Bulk discounts are available, reducing the price to as low as $6.99 per copy for orders of 50 or more.

: Print to USB, network, GDI, and PDF printers that normally lack DOS text-mode support.

If you upgrade your hardware or reinstall your operating system, you typically do not need to buy a new license. You can use the License Replacement Service to generate a new key for your updated configuration using your original order details.
