Tally Genicom 6600 Control Sequences, Print Cycles, Entering Barcode/Block Mode, Invalid Commands

Chapter 7 Control Sequences

Control Sequences

This section describes the escape sequences for entering and exiting the Industrial Graphics Barcode/Block Character mode. The commands for accessing related functions, such as selecting Normal or Double Density Block Characters, vertical or horizontal orientation of barcodes, line height, and others are also discussed. To properly use the Industrial Graphics option, the printer needs to be in the MT660 emulation.

Print Cycles

While in the Barcode/Block Character mode, print cycles occurs when either:

•the buffer fills.

•the home position is moved via a ^a Command, a Form Feed, Vertical Tab, or VFU command.

•the printer exits from the Barcode/Block Character mode (ESC[<41 where 1 = lower-case L).

Entering Barcode/Block Mode

To enter the Barcode/Block Character mode, send the following escape sequence:

ESC [<4h	ASCII
1B 5B 3C 34 68	hex

Upon each entry into the Barcode/Block Character mode, the following default conditions are established:

•Home and cursor are initialized (see Home and Cursor later in this manual).

•Normal Density printing is selected for both the Barcode Submode and the Block Character Submode.

Once you are in the Barcode/block Character mode, changing a parameter in one Submode also changes that same parameter in the other Submode. For example, selecting Double Density in Block Characters also selects Double Density in Barcode.

Invalid Commands

The following commands are invalid while in Barcode/Block Character Mode:

•Index Forward

•Index Reverse

•Save Cursor Position

•Restore Cursor Vertical Position
