NOTE: The following notation is used to define
the data type of each field in the character de-
scriptor.
(B) :Boolean (0,1)
(UB) : Unsigned Byte (0 — 255)
(SB) :Signed Byte (-128 — 127)
(UI) :Unsigned Integer (0 — 65535)
(SI) :Signed Integer (-32768 — 32767)
Format (UB)
Specifies the format of the character descriptor and data. The format number used by the
printer is 4.
Continuation (B)
Specifies whether the following data is a character descriptor block (0) or a continuation of
the data (1) associated with the previous character descriptor.
Because the escape sequence value field is limited to 32767 bytes, characters whose num-
ber of descriptor and data block bytes exceed this limit must be downloaded in two or more
blocks. Figure 8-4 illustrates the format of a character data continuation block.
