Printing plain text directly without dialogues

Hi,

I recently searched for ways printing plain (but formatted) text
directly
and without major requirements using ruby and stumbled upon wxruby,
which
seems to be a nice framework that would meet my requirements quite well.

However, since I use a local Ruby on Rails server, I would like to be
able
to select a printer as well as print the text without using dialogues,
i.e.
only using the wxruby classes to interact with the user via http
responses.

I had a look at the “printing.rb” example in the wxruby directory and
modified it to just print formatted text, as I want it, but it’s still
having dialogues. My try without dialogues was the following
non-functional
code:

begin
require ‘rubygems’
rescue LoadError
end
require ‘wx’

dc = Wx::PrinterDC.new("", “”, “”) // deprecated way to initiate
PrinterDC
on default printer

dc.set_background(Wx::WHITE_BRUSH)
dc.clear()
dc.set_font(Wx::Font.new(12, Wx::DEFAULT, Wx::NORMAL, Wx::NORMAL, false,
“Control”))

dc.set_background_mode(Wx::TRANSPARENT)

dc.draw_text( “D”, 0, 0)

Since I could not figure out the whole concept of class relations in
wxruby,
yet, I would be very glad if someone could help me and give examples for
selecting a printer and printing in wxruby without the use of dialogues.

As far as I understand, I need to create a PrintData object. This
PrintData
object could be handed to the device context PrinterDC containing my
formatted text that got into there using draw_text methods. I don’t yet
understand where this PrintData comes from, if not from a dialogue
(using
Wx::get_app.print_data).

Thanks a lot for any hints!

Have you tried cups? (cups.rubyforge.org).

UNIX only, unfortunately, but it’s a bit easier to get up & running with
it.
