In freedos? I never could put clipper printing (neither serial nor parallel) to work with freedos+dosemu, but I started to use dosemu with 1.1.4, and never tried any previous versions. Did the old versions of dosemu print from clipper apps using freedos? The only way I could put clipper apps to print using dosemu was using ms-dos or dr-dos...
