In Figure 1-1, a line feed occurs between “lesson” and “Test 1” because the space
“ “ next to “lesson” dose not fit in the horizontal range of the 200
×
400-pitch print
area. The line feed width conforms to the value specified by a command such as
ESC 3.
It is possible to set as many print areas as desired before executing FF. If print
areas overlap each other, the print area setup data are ORed with the previous
data.
If you want to erase a section of mapped data, use the CAN command. The CAN
command erases all data in the print area being specified. You can, therefore, use
an ESC W to define a print area that encloses the section you want to erase, and
then execute the CAN command, so that the section of the data is erased.
It is important to remember that any part of a character that overlaps with the
specified print area will be erased.
<Example 2>
LPRINT CHR$(&H1B) + “L”;
LPRINT CHR$(&H1B) + “W” + CHR$(0) + CHR$(0) + CHR$(0) + CHR$(0);
LPRINT CHR$(200) + CHR$(0) + CHR$(144) + CHR$(1);
LPRINT CHR$(&H1B) + “T” + CHR$(0);
LPRINT “Page Mode lesson 2 CAN command”;
LPRINT CHR$(&HA);
LPRINT “ABCDEFGHIJKLMNOPQRSTU1234567890”;
LPRINT CHR$(&HC);

First, an ESC L is sent to switch to PAGE MODE (1st line). Next, an ESC W is used
to send eight arguments, n1 to n8, to reserve a print area. In this example, the
arguments are sent in the sequence of 0, 0, 0, 0, 200, 0, 144, and 1, to reserve a
print area that measures 200 from the start point (0, 0) in the x direction and 400 in
the y direction (2nd and 3rd lines). Furthermore, an ESC T is used to specify the
print direction to be 0 (4th line).
After the above setup, print data is sent (5th to 7th lines). Finally, an FF is sent (8th
line) to produce a printout as shown in Figure 1-2.
