The most likely problem will be the drivers of the scanner it's either too old or windows 8.1 don't have the old scanners drivers so all u have to do is get the scanners drivers
The Continue statement is used inside the looping statements.
When a Continue statement is encountered inside the loop, it stops executing the current iteration ( it skips the next steps in the current iteration) and goes to the next iteration.
It then continues to execute the loop for the next iteration.
The continue statement can be used in all the looping structures ( for loop, while loop, do while loop ).
