Hi,

I have searched the forum that some people print PCB traces directly
with a flat bed plotter. Does it exist a flat bed laser printer that
can do the job?

Thanks!

I would be very surprised to learn of anything commercialy available.
What would hapen to the static charge on the light sensitive drum when
it comes in to contact with the copper? By that stage, it may have
already passed the toner on to the copper, so maybe that is not an
issue, I don't know.

It may be possible to modify an inkjet printer to do this. It used to
be possible to buy inkjets which would print diectly on to CDs, but I
am not sure where you would get waterproof inkjet ink from.

Modifying a typical laser printer with its convoluted paper path would
probably be impossible.

I get satisfactory results on an hp2200 laser printer with OHP
transparrencies. But I have two toner cartridges, one for frequent use
with documents and stuff and one brand new kept just for doing PCBs

Some copy machines were made with a straight paper path and tha
capability of handling very thick paper (cardboard).
These have been used to put toner directly on copper PCBs prior to
etching.
There was at least one model that Xerox made when copiers were fairly
new (and s l o w by present standards), and i understand that Lexmark
has made copiers/printers like that in the past few years.
Hope this is of some help.
