7. Files do not print the way the printer menu and front panel are set.
Before sending a file to a printer, many word processors send an initialization
string. This string contains codes that reset the printer to a default set of
features. Otherwise, the printer might print using features set for a previous
job. The codes will override panel or menu settings.
Check the word processor's manual to see if the initialization string can be
modified. If so, remove any codes that interfere with the printer's settings.
To set the printer to ignore the reset code, follow this procedure.
