Out ${HOME}/PDF

### Key: AnonDirName
##  ABSOLUTE path for anonymously created PDF files
##  if anonymous access is disabled this setting has no effect
### Default: /var/spool/cups-pdf/ANONYMOUS

#Truncate 64

### Key: Cut

##  extensions will only be removed if _both_ the following criteria are met:
##   - the extension (w/o the dot) is not longer than <Cut> characters
##   - the remaining filename has a minimal length of 1 character
##  set Cut to -1 in order to disable cutting
##  recommended values: pure UNIX environment : -1
##                      mixed environments    :  3
### Default: 3

#Cut 3

### Key: Label

#AnonUser nobody

### Key: LowerCase
##  This options allows to check user names given to CUPS-PDF additionally 
##  against their lower case variants. This is necessary since in some 
##  Windows environments only upper case user names are passed. Usually UNIX
##  user names are all lower case and it is save to use this option  
##  but be aware that it can lead to mis-identifications in case
##  you have user names that differ only in upper/lower case.
##     check only against user name as passed to CUPS  : 0
##     check additionally against lower case user name : 1
### Default: 1

#LowerCase 1

### Key: UserPrefix
##  some installations require a domain prefix added to the user name

### Default: 0

#DirPrefix 0

### Key: RemovePrefix
##  some installation pass usernames with a prefix (usually a domain name)
##  if you do not want this prefix to be used by the ${USER} variable for
