Selects a logo to be defined or printed. The active logo n remains in use until this command is sent again with a different logo n.
When this command precedes a logo definition, that definition is stored in Flash Memory as logo n. If there is already a different definition in Flash Memory for logo n, the first is inactivated and the new definition is used. The inactive definition is not erased from Flash and continues to take up space in Flash Memory.
When this command precedes a logo print command and n is different from the previously active logo selected, the printer retrieves the logo definition for n from Flash Memory and prints it. If there is no definition for logo n, then no logo is printed.
In the case of a previously existing application that expects only one possible logo, the printer will not receive the Select Current Logo (1D 23 n) command. In this case, the printer assigns 0 as the active logo identifier. It automatically stores any new logo definition in Flash Memory as logo 0, inactivating any previous logo 0 definition. If the Flash Memory space available for logos fills up with inactive logo 0 definitions, the 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
