It can be used with wax ribbon for Thermal Transfer printing or without ribbon for Direct Thermal printing. If printing without ribbon Media Type must be set to Thermal Direct.

After printer is installed and connected go to Control Panel- Devices and Printers , right click on Printing preferences, set correct label size, go to Dithering, set to None and click Apply. Then press feed button and keep it pressed until green LED blinks twice and release it. Printer will Calibrate itself and after that will be ready for printing.

To install as a network printer go to Control panel- Add printer-Network printer- Choose Printer isn't on a list- type in IP address from the label on side of printer (see my note below)- Device type-Print Server-Choose model of your printer. Install, configure- Add label size, calibrate and you are ready to go.

Note: I changed my Broadband provider to Virgin Media and now my LAN IP pool is different from most popular so I stopped setting Permanent IP address and putting sticker with it on a side of a printer .

Some troubleshooting tips:

If printer installs but when you send print job - nothing happens.
 Go to Control Panel - Devices & Printers - Right click on printer- choose Remove. Turn printer Off then On again. Wait until printer will  install again, go to Printer Preferences- Options-set label size- Tools- Run Calibration and  try to print delivery label again. Don't print Windows test print. If unsuccessful - repeat procedure until Windows install printer correctly or can try through Device Manager-Printers- Uninstall.
 If printer prints empty labels.
First off all make sure that labels are loaded facing up. 
Use labels supplied with printer. Some labels are designed for Thermal Transfer only- they work with ribbon only.
If printer is printing empty label after printing correct one- Run Calibration.
