I bought this cross stitch kit about month online

. I saw a fabric that has printed ink of cross stitch pattern and it is graphed. (don't know how to explain. here is the photo of the fabric). I look at the instruction but there is no explanation about this. I never done this before. I'm use to buy a cross stitch kit that has nothing on the fabric. These are my questions:
1. do you cross stitch that fabric?
2. am I supposed to wash it before I started it or reversed?
3. if yes, will it come off once I washed?
4. will it printed ink will stain the thread and change the color threads?
sorry for the questions. any recommendations?
