Abstract
An electrostatic color printer or copier having a print medium supplied from a supply roll to a takeup roll, requiring close registration for multiple printing passes over the same portion of the medium. The supply and takeup rolls are mounted in a closed housing which is airtight. The writing head and toner applicator are located in the housing. In another embodiment a limited air exchange capability through air filtration ports is provided, but the ports are shielded from the main housing for the medium so that air exchange near the print medium is limited.
