It depends on your quality and resolution criteria. PHoto tools will always be 100x better or more than carbon transfer laser printer. Half tone edge printing software helps the ink structure adhere better.
Maintenance and cleanliness of toner cartridge may affect pitting in fine line tracks.
Also type of high temperature film that will not wrinkle or curl up and has good adhesion for small vias is difficult and critical as uncurling the film may lose some dots of carbon.
High quality visual inspection of film is mandatory before etching.
Laser printers have improved a lot but sending artwork for film is best at some photoshop or printing house.
There they have >=2400 dpi resolution and much greater quality or error rate for missing or extra black specs (dust) that affects image quality.
I do not have any printer recommendations, just if you want 3 mil track and gaps, you want to go with photo tools. 20 mil track/gap, you can get away with laser and the "right" high temp transparencies, that don't turn into Ripple chips.
I find EPSON brand printers best for quality, but don't go with cheapest model in either inkjet or laser.
Some use white bond paper then soak in oil to develop as oil makes it transparent.
Others simply buy their transparencies from a printshop for $1 or so., because there is more to printing than dpi. or get fineline film developed for $10 by local Email or ftp for the phototool in the acceptable format.
