Commands
For Data Matrix encod ing, the LabelW riter SE450 printer supports o nly basic ASCII
characters 0x00-0x7F.
Data Matrix barcodes are only sup ported for 203 x 203 dpi modes. They are not su pported
for 203 x 136 dpi modes.
Parameters
n 15(0x0F)
t
optionbyte
Bit 7: “Numbers-only” compression.
Uses the ASCII number pairs compression in t he Data Matrix
specification. When this is enabled , only ASCII numbers may be
sent to the printer. Any oth erd ata will be turned into the digit 0.
0: Compression disabled
1: Compression enabled
Bit 6: Exclude rectangl es.
Excludes rectangular symbo ls for when the sy mbol size is being
auto-selected. Only effective when rand care both 0.
0: When symbol size is being aut o-selected (r=c=0), a rectangular
or square symbol may be chosen.
1: When symbol size is being aut o-selected (r=c=0), only squ are
symbols will be cho sen.
Bit 5-0: Element size
The remaining 6 bits form a binary value for the size o fth e
individual sq uare elements in each D ata Matrix symbol. This v alue
is in units o f the printers 203 d pi pixels. So, a v alue of 5 will result
in each square element in the symbol being 5 /203” wide and tall. If
this value is set to 0, the prin ter will use its default value of 4.
r
thenumber of rows in the symbol.
If bothra ndca re 0, the printer will use thesmallest supported Data Matrix symbol to
storethe data. O therwise, this shouldbe the desired number of rows, chosenf roma
supportedsymbol in the tables below.
c
thenumber of columns inthe symbol.
If bothra ndca re 0, the printer will use thesmallest supported Data Matrix symbol to
storethe data. O therwise, this shouldbe the desired number of columns,chosen from a
supportedsymbol in the tables below.
m1 themost significant byte of data length.
m2 thelea stsignifica ntbyte of data length.
