OSBYTE &05 (5) - Select the printer type.

On entry, A=&05, X=new printer output

Controls which printer output device will be used when output is sent to the printer. This does not activate and send data to the printer. VDU 2 must be used to start output going to the selected printer channel.

The value of X is made up as follows:

Value Meaning if set
0 Selects a printer sink where characters can be lost without the possibility of the system 'hanging' with a full printer buffer.
1 Selects output to the parallel output connector.
2 Selects the serial RS423 output.
3 Selects a user-supplied printer driver.
4 Selects the Econet printer.
