Lightweight Imaging Device Interface Language (abbr.
LIDIL) is a printer interface definition language used in more recent Hewlett-Packard printers.
As the name suggests, the language only supports the definition of raster documents, and is very limited overall.
It is a "host-based" protocol which is advertised with LDL in the CMD: (command set) field of the device ID string.
Such models do not support printing ASCII text.
