Returns typed in a text block do not always get printed when working with the Personal LaserWriter LS. This has occurred when working under system 6.0.7 and the 1.0 version of the LS driver (Feb, 1991).
The issue did not occur when printing the LS with the 1.1 version of the LS driver (the one released with System 7.0, created in April, 1991)
