Expanded flash memory allocation

1D 22 80
Decimal
29 34 128
This sequence of commands is used to specify the number of flash sectors to be used for different applications. The
begin and end sequence commands must be sent. All areas do not need to have flash sectors specified.
The command to request the number of user sectors is optional.
If more sectors are specified than are available the command sequence is ignored and the printer returns NACK.
If the sectors are available, and different from current parameters, all sectors are erased and the printer returns ACK.
If the sectors specified are the same as current parameters, nothing is erased and the printer returns ACK.
1D 22 80 00
request number of user sectors available, printer returns nL nH
1D 22 80 30
begin expanded flash memory allocation sequence
1D 22 80 31 nL nH
n sectors to logo/font area
1D 22 80 32 nL nH
n sectors to us
Define extended user-defined character set
ASCII
US &
s c1 c2 [character 1 data] ... [character k data]
Hexadecimal
1F 26
s c1 c2 [character 1 data] ... [character k data]
Decimal
31 38
s c1 c2 [character 1 data] ... [character k data]
Values and ranges:
s
= the number of dot rows in the character cell (maximum 64)
c
= the ASCII codes of the first
(c
1) and last (
c
2) characters respectively
c
1 = Hex 20–FF (20 is always printed as a space)
c
2 = Hex 20–FF (20 is always printed as a space)
To define only one character, use the same code for both
c
1 and
c
2
j
=
s/8
= the number of bytes (vertically) in the character cell
k
=
c2 – c1 + 1
= the number of characters to be defined in this command string
[character i data] = [ni d1 ... d(j x ni)]
for
1 ≤ i ≤ k
ni
= the number of dot columns for the ith character
, 1 ≤ ni ≤ 16
d
= the dot data for the characters
The number of bytes for the ith character cell is
j x ni.
T
he bytes are printed down and across each cell.
See the illustration.
Defines and enters downloaded characters into RAM. The command may be used to overwrite single characters. User-
defined characters are available until power is turned off or the Initialize Printer command (1B 40) is received.
Any invalid byte (
s
,
c
1,
c
2,
n
1,
n
2) aborts the command.
er data storage area
1D 22 80 33 nL nH
n sectors to permanent font area
1D 22 80 34 nL nH
n sectors to electronic journal area
1D 22 80 40
end expanded flash memory allocation sequence
n = 0xFFFF means allocate all remaining sectors to this area; only one area can specify this parameter value.
