This was the first typing system used to type on A4 size paper which was very time consuming as to write 30 lines, it used to take 15 minutes with hard keys on the typewriter. There were many difficulties being faced to write those specific lines. With the evolving technology and time, people slowly migrated and started using Fax Machine where people used to write their messages on a paper and send their messages immediately using Fax machine where scanned images to the receiver was sent. As time passed by, technology kept on evolving getting all the other manual work into one single machine called as "COMPUTER". Computer has all those things which a fax and typewriter can do. With computers, all the challenges being faced to use fax, typewriters etc, were minimized with great ease of use to the end user.
