Use
The purpose of this call is to read or set the path to use for printer output.
Notes
The printer type may also be written with OS_Byte 5. The default type is set held within OS_Byte CMOS 15.
This call does not wait for the printer buffer to empty first. Because of this, it does not enable interrupts, and so may be used to read the printer type from within an interrupt routine.
