Command error
Terminology Description
Command error The file name list is not returned. The data received after a command error is
determined is not considered as a parameter of this command.
Invalid receive data The subsequent data is ignored.
[Supplemental explanation]
• Send this command when printing has stopped. The content of the response data is not
guaranteed even when this command is received during printing.
• When you specify SZPL for "Parameter a: Language", "0: Font/logo", "1: TrueType font" settings
of "Parameter b: File type" will be ignored. So all file names registered with SZPL will return.
