PCB Etching - Transfer process

I am researcher with the Federal University of Technology, Yola, Adamawa State, Nigeria.
I specialised in electronics and I am involved in the design of several electronic circuits. I use Eagle software for all my designs (schematic & Layout).

I have problem transferring my layout onto the copper board for etching. I have tried several process of doing that including screen printing, iron-on toner, etc., but could not get satisfactory results in terms of neatness. Can one have a laser printer (or any printer) that could print directly on the copper board making it ready for the etchant? Also besides machining of tracks, is there any non-chemical etching system (using a form of light for instance)that could be interfaced with computer? I would like to have such a system if it exist. at least it will save one from the headache of transfer process.

Thank you for your response.

Hello Friend.

The best method of electronics hobbyist is the liquid photoresist spray application.
