Instance Method Details
#add_barcode_label(options = {}) ⇒ Object
add_label takes an argument hash.
[:position] Which label slot to print. Positions are top to bottom, left to right so position 1 is the label in the top lefthand corner. Defaults to 0
[:x & :y] The (x,y) coordinates on the page to print the text. Ignored if position is specified.
[:text] What you want to print in the label. Defaults to the (x,y) of the top left corner of the label.
[:use_margin] If the label has a markupMargin, setting this argument to true will respect that margin when writing text. Defaults to true.
[:justification] Values can be :left, :right, :center, :full. Defaults to :left
[:offset_x, offset_y] If your printer doesn't want to print with out margins you can define these values to fine tune printout.
