Examination of the data from the printer revealed the items had come from Sturman's computer and he was arrested two days later.
Yogain Chandarana, defending, said Sturman had destroyed the life he had built for himself.
"He has actively sought treatment for himself since his arrest 18 months ago," he said.
"He has laid out his soul in front of probation officers," he said.
"Not only does he understand his offending behaviour, but he's started getting help for himself.
"He admits though there are many areas that he had to work on.
"He has caused a complete destruction of the life he had built, a destruction of his life because of his behaviour."
"Clearly though, he did not intend to produce these images on a work printer."
Judge Lindsay Burns sentenced Sturman to eight months in prison, suspended for two years, and ordered him to take part in a sex offenders programme.
"You do not pose any significant risk, and the chance of you re-offending are at the lowest level," he said.
