Command

 

 

 

Type:

 

 

 

Description:

Carriage Right Command: Prints the contents, if any, of the printer buffer.

 

When printing to the serial port (flag –34 set), CR sends to the printer a string that encodes the

 

line termination method. The default termination method is carriage-return/linefeed. The string is

 

the fourth parameter in the reserved variable PRTPAR.

 

 

When using the HP 82240B Infrared Printer (flag –34 clear), CR leaves the printhead on the right

 

end of the just printed line.
