No, that is not correct. HP PCL printing from RISC OS and Inkjet
printing both use the same method: The RISC OS printer driver fully
rasterises the page and sends a raster image to the printer.
The RISC OS driver does not use any of the vector facilities of PCL,
it treats it as a dumb raster printer, just like an inkjet.
