Step 1. Open Nicelabel software, right click and select “Document Properties”.
Step 2. Select driver name (Eg.: Gprinter GP-1625T), Click “Printer properties”.
Step 3. Click “Print Options”, choose print speed (Speed) and print density(Darkness) as per your label content and print quality. Normally, lower darkness will protect print head and increase its lifespan, lower print speed will make logo and barcode print more clearly. You’re suggested to set up as per your actual needs.
Step 4. This is another way to modify print density and print speed:
Control panel à Printer and Fax ( or Printers & Scanners, windows 10) à Printer icon (Eg.: Gprinter GP-1625T) à Right click printer icon to find Printing preferences（ or click “Manage” to find Printing preferences, Windows 10）à “Print Options” à Print settings: “Speed” & “Darkness”
