There are several operators that function both as GDI printing directives and as printer init file commands, although the syntax may be different between the two uses. These operators can be embedded in the print file, or included in the init file, and the effects will be the same. When included in the print file, the command must appear within the top nine lines, and before any lines that generate printed output; any such command (except BIN) farther into the file will either be ignored or will produce undefined effects.
