Erase user flash sector

124 Chapter 5: Programming commands

Values and ranges:

s = the number of dot rows in the character cell (maximum 64)

c = the ASCII codes of the first (c1) and last (c2) characters respectively

c1 = Hex 20–FF (20 is always printed as a space) c2 = Hex 20–FF (20 is always printed as a space)

To define only one character, use the same code for both c1 and c2 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.

The 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, c1, c2, n1, n2) aborts the command.

n = 0xFFFF means allocate all remaining sectors to this area; only one area can specify this parameter value.

Select flash area for storing logos and user-defined characters

ASCII	GS” 0x81
Hexadecimal	1D 22 81 n
Decimal	29 34 129 n
Value of n:	n specifies
n = 0	select logo/font flash
n = 1	select permanent font flash
n > 1	reserved

Logos and user-defined characters can be stored in either flash area.

ASCII	GS @ n
Hexadecimal	1D 40 n
Decimal	29 64 n
Value of n:	49 – 51

n = 49 (ASCII n = 1) HEX 31

This command erases all 64K flash memory sectors allocated to user-defined character and logos storage. Those sectors should be erased in two situations: when the logo definition area is full and an application is attempting to define new logos, and when an application wants to replace one user-defined character set with another. In both cases, all logos and character set definitions are erased and must be redefined.
