I worked for a lab for six years in the 80s that did a lot of school photographs, as well as student ID cards for the local transit company.
The photogs were mostly independents, although some were on staff. They used a mix of Camerz and Nord long roll cameras, and the film was all 35mm unperforated.
We printed the negatives on Nord package printers, equipped (as all of the pro division printers were) with Hazeltine additive lamphouses. Later we moved some of the production to Kodak PMP printers, with the KDCPU drawers. The PMP was actually a slightly modified Lucht V-7 printer.
