    # 1 The type of data passed
    # np = new page
    # nl = new line
    # nc = new column
    # Used to enable the columinsation of reports by using the offset field. Will only left
    # Justify so if require right justify user courier font and space pad front of data.
    # Allows the usage of different font and colours by column.
    # im = new image
    # You specify one of these as the first parameter passed to identify what your upto.
    # Data is written out one line at a time so try not to exceed the characters.
    # Always start with new page.

    # The other parameters passed are
    # 2  = The column offset . This is the amount of characters from the left hand column of the line.
    # 3  = The font size to be used with the font set later. It is the text point size standard is 12
    # 4  = The name of the font you want to use as previously set
    # 5  = The size of the font on the next data line to allow for correct data throws.
    # 6  = Italic 0 = No 1 = yes > 1 get some weird results.
    # 7  = Red colour
    # 8  = Green colour
    # 9  = Blue colour 0 0 0 = black 1 1 1 = white
    # 10 = The data. This is the textual data you require.
    # If image ten contains the name of the image width and hieght ie. I2 300 60

    # For a new page line there are two extra parameters required page size and orientation. The document
    # must have the same all the way through

    # 11 = Page Size LE = letter A4 = A4
    # 12 = Page Orientation PO = Portrait LA = Landscape

    # Leaving these blank defaults to Letter Portrait

    # Again it is a good idea to check the status after every line of data output just in case an error
    # occurs like run out of disc space. OK in this example its a bit of a pain but thats life normally
    # this would be a nice loop.
