Turning Free Format On

Free Format

The GPL provides a mode which ignores all data with values less than 20 (decimal 32). Data having values below decimal 32 are collectively called Control Characters and include Line Feed, Form Feed, and Escape characters. By using Free Format Mode, the user can filter out unwanted Control Characters which may be sent by some host systems. Also, a convenient way to send GPL commands to the printer is to simply type the commands into a file and send the file to the printer. In Format Mode, a command may be spread over several lines in the file, with the printer ignoring the CR and LF characters at the end of each line.

NOTE: The Free Format ON/OFF commands may not be used within the data field of a Report or a Buffered Form.

Turning Free Format On

Free Format is turned on by sending the command ^F. After the printer receives the ^F, subsequent control characters are ignored and the printer will no longer recognize CR, LF, or FF as Pass terminators. However, the GPL language will recognize the following control code equivalents as Pass terminators:

1.^- (caret hyphen) - equivalent to the Carriage Return Command (CR)

2.^* (caret asterisk) - equivalent to the Line Feed Command (LF)

3.^, (caret comma) - equivalent to the Form Feed Command (FF)

Turning Free Format OFF

Free Format is turned off by sending the command ^O^-.
