Since there is no direct Sensitivity setting under the Options for an Intermec IPL printer, you must use a Custom Command to set the Media Sensitivity.
Go to File | Devices.
Locate the printer you need to set the Sensitivity on, then click the Options button.
In the Custom Command section, enter the following; <SI>gn,nnn Replace the n value with either 0 (Direct Thermal printer), or 1 (Thermal Transfer printer) Replace the nnn with the Sensitivity value you require.
The Sensitivity setting is a 3 digit value that is often marked on the label media being used.
