Home And Cursor
The Home position and cursor pointers in this manual are similar in func tion to
the Home and cursor pointers in a CRT terminal:
•Upon entering the Barcode/Block Character Mode, the Home positio n is
set to the extreme top-left dot in the current print line. This i s 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 fe et during a
print job without finding one of the following Paper Motion c ommands:
Form Feed Next TOF
Reverse Form Feed Current TOF
Vertical Tab Next VFU Channel 2
VFU Command Next o r Previous indicated VFU Channel
These Paper Motion commands perform three functions:
1. The Home is moved to a defined, absolute position.
2. The Cur sor position is aligned to the Home.
3. Any p rintable data being held in the buffer is printed.
Upon entering the Barcode/Block Character Mode, the cursor is aligned to th e
Home position. A Carriage Return places the cursor at the left margi n; 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 o n 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 pri nted, the
distance moved being dependent upon the block character c ell width. The
cursor does not move when printing barcodes since the length of the Ba rcode
symbol depends upon details of the Barcode type selected. Th erefore, when
printing barcodes it is necessary to use the Cursor Contro l Sequences to
properly position the cursor.
Upon exiting from the Barcode/Block Character Mode, the curso r will remain
pointing to its current vertical position.
