Tally Genicom 6600 manual Home And Cursor, Paper Motion Commands

Paper Motion Commands

Home And Cursor

The Home position and cursor pointers in this manual are similar in function to the Home and cursor pointers in a CRT terminal:

•Upon entering the Barcode/Block Character Mode, the Home position is set to the extreme top-left dot in the current print line. This is considered the starting point for horizontal and vertical positioning.

•The cursor position is defined as the current print location.

Paper Motion Commands

The printer will lose track of the Top-of-Form position and will start printing in random locations if paper movement exceeds approximately 8 feet during a print job without finding one of the following Paper Motion commands:

Form Feed	Next TOF
Reverse Form Feed	Current TOF
Vertical Tab	Next VFU Channel 2
VFU Command	Next or Previous indicated VFU Channel

These Paper Motion commands perform three functions:

1.The Home is moved to a defined, absolute position.

2.The Cursor position is aligned to the Home.

3.Any printable data being held in the buffer is printed.

Upon entering the Barcode/Block Character Mode, the cursor is aligned to the Home position. A Carriage Return places the cursor at the left margin; a Line Feed places the cursor at the left margin and also moves it down by one line feed distance. Cursor position is not affected when the Carriage Return and/ or Line Feed are used as control sequence terminators. However, the control sequence may affect Cursor position. Use of the Line Feed switch on the printer’s control panel will move the cursor forward 1/6 inch steps (in 6 LPI) or in 1/8 inch steps (in 8 LPI) and will align the Home position to the Cursor.

The Cursor also moves horizontally for each block character printed, the distance moved being dependent upon the block character cell width. The cursor does not move when printing barcodes since the length of the Barcode symbol depends upon details of the Barcode type selected. Therefore, when printing barcodes it is necessary to use the Cursor Control Sequences to properly position the cursor.

Upon exiting from the Barcode/Block Character Mode, the cursor will remain pointing to its current vertical position.
