Without a hardware key, also known as "Dongle", PrintShop Mail runs in Designer mode. In this mode, all PrintShop Mail functions are available, but you can only print up to 25 records per session and a watermark is printed over each layout output.
You can use each credit on your hardware key to print one record.

The Hardware Key
Though Windows should recognize your key by default and install it without intervention, in some cases it may not be able to do so. In these cases, you will need to manually download and install the Aladdin HASP key drivers, available online at: https://www.sentinelcloud.com/sentineldownloads/ or https://supportportal.thalesgroup.com (search for "Sentinel HASP/LDK - Windows GUI Run-time Installer").
The Credit Information dialog will also display your License type, Serial Number, remaining credits as well as the Features included in your dongle. The Features are usually the OL Care Maintenance agreement end date and other possible features depending on the version.
