Ruby Prawn PDF Prevent Header Space From Populating Next Page - ruby-on-rails

Question

I am using Prawn to generate a pdf receipt. Ideally I would like the following format:
Header
Customer Info
Items for order
Total
However when it goes to the second page there is a huge gap on the top from the Header spacing. How can I prevent it from adding the extra spacing on top?
Here is the code generating the receipt below (Sorry there is a lot of code):
class OrderPdf < Prawn::Document
def initialize(order)
super()
#order = order
bounding_box([10, 700], :width => 500) do
logo
end
message
date_shipped
order_number
bounding_box([0, -70], :width => 2000) do
bounding_box([65, 560], :width => 200) do
shipping_address
end
bounding_box([320, 560], :width => 200) do
payment_method
end
bounding_box([25, 450], :width => 500, :position => :center) do
line_items
end
end
end
def logo
image "#{Rails.root}/app/assets/images/letterhead-header.jpg" , :scale => 0.25, :position => :center
end
def message
move_down 20
text "Thanks for shopping with Dwellers. If you have any questions, please email support#dwellers.com"
end
def date_shipped
move_down 10
data = [["Shipment on #{#order.date_to_ship.strftime("%B %d, %Y")}",
"Items: #{#order.order_items.count}",
"Total: #{helpers.humanized_money(Money.new((#order.total_cents), "USD"), {:no_cents_if_whole => false, :symbol => true})}"]]
table data do
cells.style(:borders => [], :background_color => "DDDDDD", :valign => :center)
column(0).font_style = :bold
column(0).width = 400
column(0).size = 18
end
end
def order_number
move_down 10
# order_id = Digest::MD5.hexdigest "#{#order.id}#{#order.date_to_ship}"
text "Order\# #{#order.number}", size: 14, style: :bold
end
def shipping_address
move_down 10
text "Shipping address:", size: 14, style: :bold
indent(20) do
text "#{#order.user.name} #{#order.user.name_last}"
address_fields = #order.user.address.split(",")
text "#{address_fields[0]}"
if !address_fields[1].empty?
text "#{address_fields[1]}"
end
text "#{address_fields[2]}, #{address_fields[3]} #{address_fields[4]}"
end
end
def payment_method
move_down 10
#card = #order.user.card
text "Payment Information:", size: 14, style: :bold
if #card != nil
indent(20) do
text "#{#card[:card_type].capitalize} **** **** **** #{#card[:last_four]}"
billing_address
end
end
end
def billing_address
move_down 10
#billing_address = #order.user.billing_address.split
address_fields = #order.user.billing_address.split(",")
text "#{#card[:name]}"
text "#{address_fields[0]}"
if !address_fields[1].empty?
text "#{address_fields[1]}"
end
text "#{address_fields[2]}, #{address_fields[3]} #{address_fields[4]}"
end
def line_items
move_down 10
text "In this shipment:", size: 14, style: :bold
table line_item_rows + summary do
row(0).font_style = :bold
columns(1..3).align = :left
self.header = true
cells.style(:borders => [])
column(0).width = 380
row(row_heights().length-5).borders = [:bottom]
row(row_heights().length-2..row_heights().length-1).column(1).font_style = :bold
row(row_heights().length-1).column(1..2).size = 14
end
end
def line_item_rows
[["Item names", "Qty", "Price"]] +
#order.order_items.map do |order_item|
product = order_item.item.name + " - " + order_item.item.description
quantity = " x " +order_item.quantity.to_s
[product, quantity, helpers.humanized_money(Money.new((order_item.price_paid_cents), "USD"), {:no_cents_if_whole => false, :symbol => true})]
end
end
def summary
# move_down 15
data = [["", "", ""],
["Subtotal:", "Shipping:", "Total:"],
[helpers.humanized_money(Money.new((#order.subtotal_cents), "USD"), {:no_cents_if_whole => false, :symbol => true}),
helpers.humanized_money(Money.new((#order.shipping_fee_cents), "USD"), {:no_cents_if_whole => false, :symbol => true}),
helpers.humanized_money(Money.new(#order.total_cents, "USD"), {:no_cents_if_whole => false, :symbol => true})]].transpose
end
# Need this to get access to View Helpers, such as number_to_currency
def helpers
ActionController::Base.helpers
end
end
Below is how the receipt looks like.

For your flowing text that is beneath the header, you can use a span rather than a bounding_box, and it will start at the top of the page. There are some examples in the manual, just search for span in there:
