577N/A# The existence of a "PPD" environment variable in the calling environment
911N/A# indicates that Foomatic is to be used for filtering all job data as it is

911N/A# The contents of a "DEVICE_URI" environment variable in the calling
577N/A# environment indicates the method and endpoint used in communicating with

829N/A# contains a missing or unknown scheme, the URI scheme is assumed to be
829N/A# "file" and output streaming will be handled accordingly.
