firmware erases the old definitions at the next power cycle. This is the only case in which
the printer erases Flash Memory without an application command.
In the case of a new application using multiple logos, the Select Current Logo (1D 23 n)
command is used. After that, the printer no longer automatically erases the logo definition
Flash Memory page when it fills with multiple definitions. A new application using
multiple logos, writing a user-defined character set into Flash Memory, or both, is
responsible for erasing the logo and user-defined character set Flash Memory page when
the logo area is full or before a new character set is defined.
Example:
MSComm1.Output = Chr$(&H1D) & Chr$(&H23) & Chr$(n)
Exceptions:
This command is only valid for the receipt station. However, it will be processed correctly
regardless of whether the receipt station is currently selected.

*The number of bytes sent is represented by the following formula:
n = 8 x n1 x n2 (n1 x n2 must be less than or equal to 4608).
Enters a downloaded bit image (such as a logo) into RAM or Flash with the number of
dots specified by n1 and n2 in 7156 Emulation, unless loaded into Flash. The downloaded
bit image is available until power is turned off, another bit image is defined, or either
Initialize Printer (1B 40), or Define User-Defined Character Set (1B 26), command is
received.
By default, 7156 Emulation loads downloaded bit image to SRAM, while 7158 Native
Mode and 7167 Native Mode loads them to Flash.
