DC2 (see page 31) and DC3 (see page 32) also turn double-width modes
On or Off. That means they overwrite the settings of GS !
In standard mode, the character is enlarged in the paper feed direction
when double-height mode is selected, and it is enlarged perpendicular
to the paper feed direction when double-width mode is selected.
However, when character orientation changes in 90° clockwise-rotated
mode, the relationship between height and width is reversed.
In page mode, double-height and double-width are on the character
orientation.
The setting of character size is effective until ESC ! is executed, ESC @ is
executed, the printer is reset, or the power is turned off.
GS “
Function: Select memory type (SRAM/Flash)
Code ASCII:
GS n
Code HEX: 0x1D 0x22 n
Range: 48 ≤ n ≤ 51
Description:
Where to Save Logos or User-Defined Fonts
n = 48 (ASCII n = 0)
Loads active logo to RAM only. This is used to print a special logo but not
have it take up Flash Memory. A logo defined following this command is not
preserved over a power cycle.
n = 49 (ASCII n = 1)
Loads active logo to Flash Memory. This is the default condition for logo
Flash storage. A logo defined following this command is stored in Flash
Memory.
n = 50 (ASCII n = 2)
Loads user-defined characters to RAM only. This is the default condition for
user-defined character storage. Any user-defined characters defined
following this command are not preserved over a power cycle.
n = 51 (ASCII n = 3)
Loads user-defined characters to Flash Memory. An application must use
this command to store user-defined characters in Flash Memory. Any user-
defined characters defined following this command are stored in Flash
Memory. A user-defined character cannot be redefined in Flash Memory.
The Flash Memory page must be erased by an application before redefining
user-defined characters. For more information, see the Erase User Flash
Sector (GS @ n) command.
Notes:
Specifies whether to load the logos or user-defined characters to Flash
Memory or to RAM (volatile memory). The selection remains in effect
until it is changed via this command or until the power cycles.
Additionally the selection n= 51 remains in effect until ESC @ is received.
ESC @ will reset this setting to n=50.
