What the printer driver does with the data from the print job is printer dependent and is not within the scope of this article. Sample source code can be found in the Haiku source code repository. For raster printer drivers see Haiku printer drivers Canon LIPS, PCL5, or PCL6. For "vector" printer drivers see the Haiku PDF printer driver. In addition, the main program may not have anything useful to do at all if it cannot continue without the data being read through the I 2 C port. An interrupt-driven driver does, however, provide some advantages. The time spent waiting for a conversion to be completed, can be used for number crunching or updating a display.
