Toner transfer works fine for HF , if you do a proper layout for the circuit. May need to provide a solid ground-plane.
I have been doing toner transfer for years, and the limiting factor I found was the brand of toner. With several different brand printers I could get good results with the OEM cartridge, but could never get usable results with generic replacement cartridges. I saw the cold toner transfer method in an earlier instructable, and gave it a try. https://www.instructables.com/id/Heatless-cold-Tone...Now by slightly modifying the method ( running the board with saturated paper through a laminator with out warming it up first) I have been able to get great results with both single and double sided boards. The picture is of a double sided board laid out for mostly 1206 size SMD components. I also dip the boards in some "liquid tin" for a minute to make them easier to solder to.
