I see, you are talking about baking paper, yes it works.
We use only the Bakery release paper type here in Oz.


Parchment paper

Modern parchment paper is made by running sheets of paper pulp through a bath of sulfuric acid
(a method similar to how tracing paper is made) or sometimes zinc chloride.
This process partially dissolves or gelatinizes the paper.
This treatment forms a sulfurized cross-linked material with high density,
stability, and heat resistance, and low surface energy – thereby imparting good
non-stick or release properties.
The treated paper has an appearance similar to that of traditional parchment,
and because of its stability is sometime used for legal purposes where traditional parchment was used.

Bakery release paper

The stickless properties can be also achieved by employing a coated paper,
for which a suitable release agent — a coating with a low surface energy and capability
to withstand the temperatures involved in the baking or roasting process —
is deposited onto the paper's surface; silicone (cured with a suitable catalyst) is frequently used.

i have been thinking about this, if inks are now available that are etch resist, what you all need is an older style of printer, called a bubblejet printer, its basically like an inkjet, but has ink tanks instead of cartridges, infact some canon and epson printers sold as inkjet are in fact bubble jet type, its just the tanks are small and removable like cartridges, this type of printer still turn up cheap here, very often a3 poster size, any printer that takes ink from a tank will be better here, as there is no electronics on the tank/cartridge.
a lot simpler too but would do what you are after, but you have to have etch resist ink.
infact i threw out an a3 size bubblejet printer last year, as i could no longer find the RGB kind of inks(CMY are no good for them print wise), but for this it would not matter, as long as it prints the traces properly it would work.

Alternatively you could build a small CNC machine to mill out the PCB directly.
