3.3 Button and Indicator
SP-DVII micro printer has one button, which is feed button “LF”
SP-DVII micro printer has one indicator, which is online indicator SEL. When SEL
indicator light on, it means printer online, otherwise, printer is outline or busy.
(1) Self-test mode:
Press LF button and switch on, the printer will print self-test receipt.
(2) Paper feeding mode:
Press LF button, the printer will feed paper, then release it, the printer will stop
feeding
3.4 Self-test
The self-test will check the condition of printer. If the printer prints out the self-test receipt
correctly, it means the printer works normally. Otherwise it needs to repair.
Refer to 3.3 of how to print self-test.
3.5 Printer Initialization
There are three kinds of modes for printer initialization. The first one is that the host sends
command to the printer with control code ESC@, realizing initialization through software.
The second one is that realizing initialization through self-test. The third one is that power
on initialization. The contents of initialization include: select default of each control code,
namely the dot number of line spacing is 3, no binding length, vertical and horizontal tab
value are both 0, left and right margin width are both 0, enlarging multiple is 2; cancel all
13
the user-defined characters or graphics characters; select character set 1 and select non
reverse white print etc.
For watching the receipt bar conveniently, the default direction are different, for example,
T series is forward, others are inverse.
Chapter 4 Print command
4.1 Summary
Dot matrix printer support printing commands all compatible with traditional ESC printing
commands. Each command is described in following format:
Command name Function
Format: ASCII: the standard ASCII character sequence
Decimal: the Decimal number sequence
Hexadecimal: the Hexadecimal number sequence
Explanation: what the command does and how to use it.
Example: some examples are listed to illustrate the command for better understanding.
The following is the description of each command according to the function of each
command. The following examples all printed with A series, and inverse, the bottom of
receipt bar is printed first.
4.2 Commands details
4.2.1 Paper Feeding Commands
LF Feed Line
Format: ASCII: LF
Decimal: 10
Hexadecimal: 0A
14
Explanation:
All the data in buffer will be printed and feeds paper forwards one line when send one LF.
The effect is the same as CR, if using both LF and CR commands, only one command will
work.
ESC J n Dot Line Feed
Format: ASCII: ESC J n
Decimal: 27 74 n
Hexadecimal: 1B 4A n
Explanation:
The printer feeds paper n dot lines. n=0~255.
This command sends carriage return and feed line. It won’t influence the
latter feed line command. If you need to feed paper immediately but no carriage return,
can use ESC J command. Line spacing will be adjusted automatically when using
commands ESC V, ESC W and FS W for enlarge characters.
ESC 1 Set n Dot-line Spacing
Format: ASCII: ESC 1 n
Decimal: 27 49 n
Hexadecimal: 1B 31 n
Explanation:
The line spacing is set to n dot-lines for future Line Feed command.
n=0~255, default setting n=3 for text printing, n=0 for bit map printing
when using ESC K command.
The BASIC programs for observing the effect of this command are as
below:
FOR I=1 TO 11 STEP 2
LPRINT CHR$(27);CHR$(49);CHR$(I); ‘ESC 1 set line spacing
LPRINT “RMWD TEST” ‘print character string and feed line
NEXT I
The print result of the said programs is as following:
15
4.2.2 Format Setting Commands
FF Feed Page
Format:: ASCII: FF
Decimal: 12
Hexadecimal: 0C
Explanation:
Feed paper to the beginning of the next page.
ESC C Set Page Length
Format: ASCII: ESC C n
Decimal: 27 67 n
Hexadecimal: 1B 43 n
Explanation:
The page length is set to n character lines. n=0~255, when n=0, the page
length is 256 lines. Default n=40.
ESC N Set Binding Length
Format: ASCII: ESC N n
Decimal: 27 78 n
Hexadecimal: 1B 4E n
Explanation:
16
The binding length is set to n lines. n=0~255, default n= 0. In SP-T,
binding length denotes the number of blank line between one page and the next page.
Example: set binding length to 3 lines, send the following sequence to the printer:
ASCII: ESC N ETX
Decimal: 27 78 3
Hexadecimal: 1B 4E 03
LPRINT CHR$(27); “N”; CHR$(3);
The BASIC programs for sending the said sequence are as below:
LPRINT CHR$ (27) ; “N”; CHR$ (3)
ESC O Cancel Binding Length
Format: ASCII: ESC O
Decimal: 27 79
Hexadecimal: 1B 4F
Explanation:
The binding length is set to 0 line, it means the printer will print line-by-line, won’t vacate
blank lines between each page.
ESC B Set Vertical Tab Value
Format: ASCII: ESC B n1 n2 n3…NUL
Decimal: 27 66 n1 n2 n3…0
Hexadecimal: 1B 42 n1 n2 n3…00
Explanation:
The vertical tab positions are entered as n1, n2 and so on, all of
these should be within the page length set by ESC C command.
Command NUL added at the end indicates the command is over.
All vertical tab positions that input can be deleted by using this command
in ESC B NUL format. VT command is to carry out vertical tab, the paper fed to the next
vertical position.
Example: set three vertical tab values at 2nd line, 5th line, 8th line in
one page, you can send the following commands:
17
ASCII: ESC B STX ENQ BS NUL
Decimal: 27 66 2 5 8 0
Hexadecimal: 1B 42 02 05 08
00
The BASIC programs for this example are as below:
LPRINT CHR$(27); CHR$(66);CHR$(2);CHR$(5);CHR$(8);CHr$(0); ‘ESC B
command
LPRINT CHR$(11); VT command
LPRINT “SPRM1” Print character string
LPRINT CHR$(11); VT command
LPRINT “SPRM2” Print character string
LPRINT CHR$(11); VT command
LPRINT “SPRM3” Print character string
The print result in dot matrix is as following:
VT Carry out Vertical Tab Value
Format: ASCII: VT
Decimal: 11
Hexadecimal: 0B
Explanation:
Feed paper to the next vertical tab position which is set by ESC B
command.
Notice: if there is no vertical tab value setting, or the current position
equals or is beyond the last vertical tab position, VT command is to feed
paper one line only (same to LF command).
