The printer will enter Self Test mode
There are also two ways to exit the Self-Test mode
.
(1) The printer will exit Self-Test mode automatically
after printing the Self-Test sample
.
(2) When the Self-Test Sample is being printed, it can be
tenninated by pressing the SEL button
.

. On/Off Line Mode
After switching on or exiting from the Self-Test mode, the
printer entern On-Line mode
. The SEL indicator lights up
.
Press the SEL button, SEL indicator goes off Printer enters
Off Line mode and can not receive data
. Press SEL again
.
Printer re-enters the On-Line mode
.
SEL has another function
-
to interrupt the printout
. If
SEL is pressed and then released during a printout, the printer
will stopaft
.ercompletingthecurrentline
. Atthispointyoucan
feed more paper
. To complete the printout, press and release
SEL button The printer will run again at the point printout
was interrupted
.

. Paper Feed Mode
When print procedure is interrupted, SEL off, the printer enters
Off-Line mode
.If paper has tobe replaced press LF button Printer
will feed paper without printing then release LF, printer will stop
paper feed

.4 Self-Test
Self- Test cheeks condition of printer
. lf the printer prints out
the Self-Test sample correctly lt is working normally
. Eventually
faults are not caused by the printer but by the interface on host
computer
.lf Self- Test does not tun or print out a faulty sample
,
check power supply If power is OK
,
the printer itself requires
attention
Self-Test prints out all characters in the fonts
. Then prints the
messaltes about interface type and printer head mode[
.
After Self-fest the printer enters On-Line
m

. ltcan then
Receive data from the host computer

.5 Printer Initialization
Initialization includes default value settings
. Default
values are
: 3 dot line spacing, 40 lins Form length, 0 values
of vertical tab and horizontal tab, 0 values ofright margin and
left margin, normal alphanumeric and graphic character size
(i.e.
enlarge factor is 1)
. Initialization clears all user defined
characters and data in printing buffer, and selects character set
1, then sets printer to On-Line mode, i
.e
. ready to receive
commands and data
.
There are three ways to realize Initialization
.
First
-
run Initialization software on master computer
.
Master computer sends Utitialization command (ESC
L)
to
printer
.
Second
-
through Self-Test procedure
.
Third-power on Initialization

.1 Summary
DPN-833/8233/8333 provides up to 40 printing commands
These command special functions
(1) Defme formatting
.
(2) En large or condense of characters
.
(3) Print image graphics
.
(4) Select font
.
(5) Define special characters
.
(6) Other
.
Some of these commands consist of a one byte control
code
. Some are ESC code sequences
. The latter sequences
start with "ESC" code, followed by other alphanumeric
characters
.
Printer's control codes (especially ESC control codes) are not
standardized Every printer manufacturer has his own code system
.
Control codes for the DPN-833/8233/8333 series were designed with
reference to the popular pnnter
.Hence ,they are compatible with most
printers
.
Printing commands are described under five headings set

Bit Image printing
Explanation
:
The value ntand n
; form a 16-bit number W with n
t
as the
low byte and n, asthe high byte, This number W represents the
widthofagraphic
. Wshouldbeintherangeltothemaximum
number of dots per line
.
This command prints graphics with W X 8 dot matrix
.
The width of such graphics is W dots, and the height is
L
dots
.
Each column has 8 dots and can be represented by a byte (8
bits)
. The MSB ofthe byte corresponds to the uppermost dot
ofthe column
. "1" black "0" while
.
The data are the bytes of relative columns in the graphics
.
The number of bytes should equal W
.
Example
:
To print the special graphics shown below, ESC K
command is used
. This example is 16 x 16 dot matrix (16
columns and 16 rows), and should be
divided into two parts
(upper & lower) for printing
. The line spacing shouldbeset 0
by using the command ESC 1 n
. So nt-16 and n,° 0 ,that is
\1'=16
. for each 8 rows
. There are all together 3 2 bytes of data
.

Explanation
:
This command is designed to print curving graph lines
along the paper feed (vertically)
. The value m is the number
of lines and should be within the range 1 to the maximum
number ofthe dots per line (See Section
1
.3)
.
In a horizontal dot line, there are m intersections of m
curving graph lines
. The value n
t
, n2, . .
. , n k represent the
position of these m intersections
. The number of n
k
must
equal m
. Each n k
must fall within the number of dots per line
.
The last CR (Carriage Retum) lets printer print one dot line
.
As all horizontal lines are printed out with respective n
k
values, m curves will appear in the printout
.
Example
:
To print out graph lines ofthe five equations
:
Y 1=50+40*EXP(-0
.01 *X)*SIN(X/10)
Y2=50-40*EXP(-O
.0 1*X~*SIN(X 10)
Y3=50
Y4=50+40*EXP(-0
.01 *X)
Y5=50-40*EXP(-0
.01 *X)
Program with BASIC language as below
:
10 FOR X=0 TO 150 `print 150 dot lins
20 Y=INT(40*EXP(-0
.01*X))
30 YY=INT(Y*SIN(X/10))

Explanation
:
Hexadecimal Dump print mode is tumed on if n=1, and
tumed off if n=0
. If you execute programs or list program in
Hexadecimal Dump print mode, all data sent from the host
computer will be printed out in hexadecimal
.
Example
:
W henthe following 4 data are sent from the host computer
after the command ESC
