Page mode
Starting from version 1.40, the printer supports page mode. For this mode is needed larger RAM, so it
is possible, that some of the older printers will not support it. You can check this using command
ESC Z
(bit 29.6 will be set if page mode is supported).
New 13 commands are added in page mode, most of the old command work differently.
In standard mode the device prints the data after receiving new line command (LF or CR depending on
memory switches) or when the line is wider than the defined print area.
In page mode the result of incoming commands is forwarded to a reserved memory area (page). The
page place and size is defined using command
ESC W
. Command
GS T
selects the print direction in this
page. At the end the collected information is printed using one of the commands, provided for this.
Commands
ESC FF
and
GS FF
print only the currently defined page, but command
ESC Z
prints the area
between the first and last line containing at least one black point.
All commands except
GS L
and
GS W
work in page mode. The centering and right alignment
(command
ESC a
) is working in the currently defined page width
.
Ruled lines
Starting with version 1.48 new commands added to make printing tables in standard and page mode
easier.
The printer has two line buffers with size the maximum printing width (paper width in standard mode or
the selected page width in page mode). When ruled lines are active, then every horizontal line of the text
line is combined with the selected ruled line buffer. Bit ‘1’ in the ruled line buffer is a black dot in OR mode
and inverts the color of the dot in XOR mode. Two commands allow the ruled line buffers to be printed
without combining with a text line.
When pressing the
FEED
button, no ruled lines buffer is applied.
All ruled lines commands start with symbol
DC3
(ASCII code 13h). Please see command
DC2 =
, too .
Warning!
The ruled lines print position depends not on
GS L
and
GS W
(left margin and line width) and is
always at the beginning of the line (or at the beginning of the printable area in page mode). The printed
text and graphic change their position according these commands.
When printing 180 degrees rotated lines (command
ESC { 1
) ruled lines buffers are not rotated!
