IBM SUREMARK TI8 - Manual (Page 137)

There are twenty-two 64 KB sectors, for a total of 1.4 MB of flash memory available
for allocation. The MCT value represents the number of 64 KB sectors assigned to
the respective function. The amount of memory allocated to each function is
specified by the value stored in its respective MCT location.
The user-defined thermal characters and user-defined impact characters are limited
to one 64 KB sector each.
To change the memory allocation for any function, all memory partitions must be
erased. If memory is not erased, an MCT write error status is returned. After the
MCT values are written, the new ones take effect only after a reset. The new
memory allocations begin with the lowest MCT address and increment up. Memory
is allocated until all requests are satisfied or until all memory has been used.

EIA-232 Syntax:
GS * logo# n1 n2 data or X'1D;2A;logo#;n1;n2;data'
where:
logo# The logo number being stored.
v range = 1 to 40 for all models except TI8 and TI9
v range = 1 to 255 for Models TI8 and TI9
n1 One-eighth the number of dots in the horizontal direction (width = 8
× n1).
range = 1 to 72 for a thermal logo.
range = 1 to 59 for an impact logo.
n2 One-eighth the number of dots in the vertical direction (height = 8 ×
n2).
range = 1 to 255 for a thermal logo.
range = 1 to 5 for an impact logo.
data The data to form the graphics image. The number of data bytes for
the image is n1 × n2 × 8
Purpose:
To store all-points-addressable print messages.
