Hi Claudina,
Thank you for your interest in Syncfusion product.
If you want to print the multiple selected range in GridControl, then please try using PrintingMode property in QueryRowHeight event to achieve this behavior. In GridControl the PrintMode property set to true, when the GridControl has been moved to printing mode.
Please refer the sample in below location:

Let me know if it helps.
