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.
