Pam,
Is this the only copy of the county air photos? If so, I would hope you or another party would consider taking on the preservation and access work that goes along with the collection.
Regarding printing from digital to paper, if the scanning rate chosen adequately represents the actual film, printing then becomes a function of using a printer capable of delivering the amount of detail contained in the e-file.
Touching on the stereo portion, the orthos should be able to be ingested by a GIS program. Hopefully, the files are GeoTIFF.
Best,
