Is is normal for newly plastered walls to have drying lines and cracks all over them?

"New plaster should not have cracks in it at all unless the background is moving.. but also if the are hairline cracks could be being dryed out to fast"

"No this is not normal this can mean that the mix was not made or applied correctly.

"This can happen on plastering jobs, where the background plaster e.g "horse hair" plaster has not been adequately primed. Although old properties with this type of plaster even if primed properly, can still suffer with hairline cracks. The only way to avoid this, is the remove old plaster and start again."
