The printer has the plural printing data acquiring routes, any of them
being acquired through the system interface system.
The printing data are developed to an equivalent of one page of the
image data in the image processing unit, and then printing operation
starts.
When the printing operation starts, the BJ head is initialized,
commencing paper pick up. The printing position of the paper is
counted after the TOF inlet sensor detects the TOF mark on the
paper (or the gap between the labels). Printing operation will take
place after the image processing unit sends an equivalent of one line
of the printing data to the image formation unit at the time when the
printing position reaches the black head. Transmission and printing
of an equivalent of one line of the printing data are repeated in
synchronization with the feed of the paper to perform black
printing. From now on, each time when the label reaches the cyan,
magenta, and yellow heads, transmission and printing of an equiva-
lent of one line of the printing data are repeated for each colour,
completing an equivalent of one page of colour printing.
