AppleWorks: No Bi-directional Printing on a DWP or Sprint 11
You cannot print a file bi-directionally on an Apple Daisy Wheel or Qume Sprint 11 printer from any version of Appleworks.
OA-H does cause these printers to print bi-directionally, but only what's on the screen, not the entire file. To print the entire file, you must use OA-P, which cancels bi-directional printing.
