Use
The purpose of this call is to determine the path to use for printer output.
Notes
The type may be read (and written) with OS_Byte 245. Values in the range 0-7 can be set as the default type in OS_Byte CMOS 15 and *Configure Print.
If a serial printer is in use, setting bit 0 in OS_Byte 3 will mean that the characters are printed twice.
