32# The existence of a "PPD" environment variable in the calling environment
33# indicates that Foomatic is to be used for filtering all job data as it is
34# streamed to the output device (printer).
35#
36# The contents of a "DEVICE_URI" environment variable in the calling
37# environment indicates the method and endpoint used in communicating with
38# the output device (printer).  If no DEVICE_URI is present or the value
39# contains a missing or unknown scheme, the URI scheme is assumed to be
40# "file" and output streaming will be handled accordingly.
