E-Paper not working

I'm using 2.13inch epaper and arduino uno r3. i try to load the sample code from the Waveshare.

but my epaper not at all blinking for this code.but it's print in Arduino IDE Serial Monitor.
May i know the reason for this problem?

Actually i want to print Product name and barcode in 2.13 inch E-Paper.Please suggest any demo code to implement this ..

yes.I Referred waveshare. i'm using Arduino Uno r3 but they used Arduino Uno Plus.I hope this is not a actual reason to not blinking E_Paper. I'm just confused where i'm lacking?? @sherzaad

Please use the Arduino Forum Display for technical questions on e-paper displays, e.g. Waveshare e-paper displays with SPI

You could try this library: GitHub - ZinggJM/GxEPD2: Arduino Display Library for SPI E-Paper Displays

Don't connect data lines directly to 5V Arduino pins, use resistor voltage dividers!
