IBM 4400 manual Initialize Parameters, N4 Values, Function OFF, N5 Values

Initialize Parameters

n4 and n5

Parameter bytes n4 and n5 allow you to define several configuration parameters that will override conflicting factory default and memory-based configuration values when the printer is reinitialized. Possible values for n4 and n5 are listed in Table 28 and Table 29, respectively.

NOTE: In addition to the formatting from bytes n4 and n5, this command sets the current line as top-of-form. It also clears vertical tabs and sets the horizontal tabs at every eight columns, starting at column 9.
