Scenario:

Assume that a printer needs to deal with different situations, e.g., it can be idle waiting for a job, it can be
printing a job and not taking any new jobs due to limited memory, it can be out of paper, or ink or it has
printed so much that it is overheating and needs a break to cool down.
Problem: This printer supports a number of actions (print/ reset/ get status) that all need to behave
differently depending on the situation the printer currently is in. Implementing these actions
would lead to huge IF-THEN-ELSE statements.

from this scenario I want to answer this two tasks:

task1) Select the most appropriate design pattern to use for this problem and Clearly motivate how
this pattern addresses the problem.

task2) Explain how this pattern should be implemented and show an appropriate class diagram to illustrate
the implementation of your pattern. (No code). Don’t give a generic class diagram for this pattern but
make it specific for that design problem.
