Mark was great. He was very savvy about how best to correct my ongoing printer problems. I'll try my best to follow his instructions so this doesn't happen anymore. At 73, my memory isn't all that great anymore, though.
Mark is is a very talented teacher; he is knowledgeable and I appreciate his patience with my 73-year-old brain. He had to repeat certain steps several times which I really appreciated. He's going to be a great teacher when he starts teaching in schools.
