ruby-on-rails - 打印 Prawn 生成的pdf

Question

将 prawn gem 用于 ruby​​-on-rails 网页，是否可以将打印请求发送到打印机设备以打印我使用 prawn 生成的 pdf 页面？

Answer 1

看起来您想使用 prawn-print .

# Open print dialog, but don't autoprint.
pdf = Prawn::Document.new
pdf.text "I installed Adobe Reader and all I got was this lousy printout."
pdf.print

# Autoprint it on the default printer, when opened.
pdf = Prawn::Document.new
pdf.text "Help! I am trapped in a PDF factory!"
pdf.autoprint

# Autoprint it on a printer where the name includes "LaserJet".
pdf = Prawn::Document.new
pdf.text "Help! I am trapped in a PDF factory!"
pdf.autoprint "LaserJet"
