[Outline] Specified test printing will be executed.
• pL, pH will specify the number of subsequent parameters by (pL + (pH x256))bytes.
• “n” will specify the paper for test printing in the following table.
n Category of Paper
0, 48 Basic paper (Paper rolls)
1, 49
2, 50
3, 51
Paper rolls
• “m” will specify the category of test printing in the following table.
m Category of Test Printing
1, 49 Hexadecimal dump
2, 50 Printer’s status printing
3, 51 Memory SW settings
[Caution] • This command is only valid when processed at the head of a line during the
STANDARD
MODE.
• The command will be ignored in PAGE MODE.
• During macro definition, if this command is processed, the macro definition is
suspended, and the command starts being processed.
• Printer will reset its hard disk after finishing test printing. Therefore, the printer
makes download characters, bit map images and macros undefined, clears there
caption buffer/print buffer, and returns the various settings to defaults. At this time,
the DIP switches are read again.
• Printer will be BUSY when the processing of the command starts.
