The procedure of determining the value for every colimm must be performed for
each of the five lines. It is also important to document the number of columns
contained in each line. The number of columns contained in each line and the
value for each column (in parenthesis) is given below.
Line 2 contains 26 columns. Column 1 (255); columns 2 through 5 , (0); columns
6 through 11, (255); columns 12 through 15, (0); column 16, (143); column 17,
(207); coliimn 18, (47); column 19, (63); column 20, (31); column 21, (15);
column 22, (4); columns 23 and 24, (2); columns 25 and 26, (1).
Line 3 contains 35 columns. Column 1, (255); columns 2 through 5, (0); columns
6 through 11, (255); columns 12 through 15, (0); columns 16 through 21 (255);
columns 22 through 25, (0); column 26, (63); columns 27 and 28, (191); columns
29 and 30, (127); column 31, (63); columns 32 and 33, (32); columns 34 and
35, (16).
Line 4 contains 31 columns. Column 1, (255); columns 2 through 5, (0); columns
6 through 11, (255); columns 12 through 15, (0); columns 16 through 21, (255);
columns 22 through 25, (0); columns 26 through 31, (255).
Line 5 contains 35 columns. Column 1, (240); columns 2 through 5, (16);
columns 6 through 11, (240); columns 12 through 15, (16); columns 16 through
21, (240); columns 22 through 25, (16); columns 26 through 31, (240); columns
32 through 35, (16).
In order to send the value for each column and print the figure, the user must first
enter Epson graphics mode. This is done by sending the printer a sequence of
four codes.
FORMAT:
ESC “K” N1 N2
The ESC “K” instructs the printer to enter single density Epson graphics.
N1 and N2 designate the number of graphics bytes (number of columns) that are
to be sent to the printer.
NOTE
The printer will “hang-up” if the number of graphics bytes
sent is less than that specified by N1 and N2. Also, the printer
exits graphics mode after receiving the number of graphics
bytes specified by N1 and N2. Any bytes the printer receives
after exiting graphics mode will be printed as text mode
characters.
