Guys i need ur help.Here is the scenario

One Printer Can have multiple PriterTrays and PaperSizes,Schema is given below.

Table Schema : 3 Tables

1)Printer:

PrinterId,Name,PrinterStatus

1,ABC,2

2)PrinterTray

PrinterTrayId,Name,PrinterID

100,xyz,1

101,ddy,1

2)PaperSizes

paperSizeId,Name,PrinterId
