This call reads or sets the printer NoIgnore state. If bit 7 is clear then the ignore character set by OS_Byte 6 or OS_Byte 246 is filtered from the printer output stream. If bit 7 is set, then the printer stream passes all characters. The default state of this bit is stored in CMOS byte 15.
The default setting of this flag is controlled by *Configure Ignore and may be changed temporarily using *Ignore.
