The meaning of pattern e1 is to receive current bit flag processing instruction ESC
*, ESC& (instruction of printing position flag data) the 1st byte (ESC).When getting into Mode A, when the reception data value is ESC, the pattern of dividing a word with a hyphen at the end of a line e1.Equally, when the pattern of entering e1, then, the reception data value is
*, during &, the pattern E that states after dividing a word with a hyphen at the end of a line, during other situation, the Mode A of dividing a word with a hyphen at the end of a line.
The meaning of pattern e2 is the 1st byte (FS) that receives current bit flag processing instruction FSg1m (with the instruction in the bit flag data write non-volatile memory).When getting into Mode A, when receiving data value and be FS, the Mode A of dividing a word with a hyphen at the end of a line.
The meaning of pattern e3 is the pattern that receives the 2nd byte (g) of bit flag processing instruction FSg1m.During entering pattern e2, when the data value of reception is g, the pattern of dividing a word with a hyphen at the end of a line e3, during other situation, the Mode A of dividing a word with a hyphen at the end of a line.Equally, when getting into pattern e3, then, the data value of reception is 1 o'clock, the pattern E that states after dividing a word with a hyphen at the end of a line, other situation, the Mode A of dividing a word with a hyphen at the end of a line.
The meaning of pattern E is as pre-treatment meta sign processing instruction ESC
*, ESC&, FSg1m.In this pattern, set " handle in real time and forbid " in the mark region 114 in RAM104.
At bit flag processing instruction ESC
*, among the ESC&, FSg1m since with parameter-definition the data length of bit flag data of later transmission, divide a word with a hyphen at the end of a line pattern E from pattern e1, e3 after, then, receive the data rows of demonstration by ESC*, ESC&, FSg1m traffic bit flag data length.In pattern E, this value that receives is set in the statistical regions 115 in the RAM104,1 byte of later every reception just deducts this value.
This statistical value reaches at 0 o'clock,, after the reception of binary data finishes, in mark region 114, sets " handle in real time and allow " that is, from the pattern E Mode A of dividing a word with a hyphen at the end of a line.
Like this, in the present embodiment, when printing equipment receives the bit flag processing instruction; Real-time processing instruction is forbidden in setting; When the reception of bit flag processing instruction finishes, set again and allow the real-time command processing, so there is no need to use real-time processing to forbid, allow instruction.
On the other hand, in signal conditioning package, bit flag processing instruction data rows; Even contain and the real-time identical data rows of processing instruction data rows; Recognize that kind in the past, and there is no need to transmit and implement to handle inhibit command, can send the bit flag data to printing equipment more easily.
