18. ESC 8
Temporary store current print settings
[Code]
[1Bh] + [38h]
[Outline] Use command ‘ESC 9’ to restore the parameters. The parameters stored are:
double height/width symbols, rotated by 90
º degrees symbols, font size, underline,
emphasize, italic style, downloaded font active, rotated by 180º degrees symbols,
black and white inverse symbols, reverse print direction (from right to left),
Chinese/Arabic code table selected (only in the Chinese/Arabic printer version), print
density, printing speed, left margin, printing width, line height, intercharacter space,
country, code page, Euro symbol position, barcode width, barcode height, barcode
HRI position.
[Caution] The printer uses this command when printing full and short self-tests. So if a self-test
is printed, the printer will store the print settings active at the time the printing starts.
19. ESC 9
Restore the previously saved settings
[Code]
[1Bh] + [39h]
[Outline] This command restores the setting saved with ESC 8. If such a command has never been issued,
the printer restores the settings as they were at printer power on.
20. ESC = n
Data Input Control
[Code]
[1Bh] + [3D] + n
[Range] {0 <= n <= FFh}
[Outline] Selecting equipment in which data input from the host is effective.
• Only bit 0 is defined
Value 0: Selected
Value 1: Not selected
• When the printer has not been selected, this printer abandons all the received data until it is
selected by this command.
[Caution] • Even when the printer has not been selected, it can become BUSY state through printer
operation.
• When the printer is deselected, this printer discards all the data until it is selected with this
command.
[Default] • The initial value of n is "1".
21. ESC > n
Set Factory Defaults
[Code]
[1Bh] + [3Eh] + n
[Range] {0 <= n <= FFh}
[Outline] This command writes the current code tables, the intensity level and the current printing speed into
the flash memory. These values will be retrieved at first power up or after a power failure.
• Value of
n
doesn’t matter. It is left for compatibility purpose.
[Default] • The initial values are: code tables 0 (US American CP437), intensity level 100%, maximum
printing speed.
22. ESC @
Restore saved to nonvolatile RAM settings
[Code]
[1Bh] + [40h]
[Outline] Clears data stored in the print buffer and brings various settings to the initial state.
[Caution] • Data inside the internal input buffer are not cleared.
