How do I change Zebra print darkness?

Set darkness for that printer in the editor (0 to 30) or on the device, slow the speed a little, print one test, then raise in small steps. Clean the head if 20+ is still pale.

Do I need ZebraDesigner or a paid license?

No. Design in the browser and print with Zebra Browser Print, or export PNG, PDF, or ZPL. No desktop designer seat.
