Step 4 Send the attribute byte
Every new defined character which will be loaded into the DLL
RAM
needs a control byte , the attribute byte.
This
attribute byte has three functions.
ascender
or descender
start column (only affects proportional printing)
stop column (only affects proportional printing)
2
4
8
16
32
64
........ last print column of character
128 ........ ascender
1 =ascen der
In the example the character starts in column 0 and ends in column
10. A maximum of 12 columns can be loaded but the last column
is reserved for proportional characters, which are printed in
enhanced mode. The standard setting for column 11 for non-
proportional
use of the self created character set is 0. When the
most significant bit is set to 0 the complete matrix is shifted 1 dot
down to print descender characters. The attribute byte for the
example character is 10001010

or 138

If you do not want to print in proportional mode you only need to
specify if the character is to
be printed with the top 8 pins (attribute
byte =128) or with the bottom 8 pins (attribute byte= 0).
