Must a Sofer computer check his work?
Question:
I am a Sofer, I was wondering if it is a chiyuv to computer check my work or is it enough to go over it three times as mentioned in Shulchan Aruch?
Answer:
According to most poskim there is no obligation to use a computer, although it is very recommended (obviously in addition to human checking).
