Use cases: 1. User wants to print PS document on PS printerText
(reggae opening text as Document common format) -> Postscript
(Reggae, only data type is changed) -> Filter (Reggae) using
data from Global Postscript Preferences (MUI), or application ->
Device dependent postscript (reggae) -> spooler
(printer.device?)-> output device 2. User wants to print PS
document on non-PS printer.Text (reggae opening text as common
format) -> Postscript (only data type is changed) -> Filter
(Reggae) using data from Global Postscript Preferences (MUI), or
application (from PPD)-> Device dependent postscript (reggae)
-> PS Rasterization to cups raster metaformat (reggae?) ->
conversion to device dependant data (reggae or rasterto* CUPS
converters) ->spooler (printer.device?)-> output device 3.
User wants to print image (non-PS document, which can be
rasterized) on PS printer.Image (reggae opening to common format
RGBA32) -> imagetops (reggae filter) -> Filter (Reggae) using
data from Global Postscript Preferences (MUI), or application (from
PPD)-> Device dependent postscript (reggae) -> spooler
(printer.device?)-> output device 4. User wants to print image
on non-PS printer.Image (reggae opening to common format) ->
Filter (Reggae) using data from Global Postscript Preferences
(MUI), or application -> cups raster metaformat (reggae)
->conversion to device dependant data (reggae) -> spooler
(printer.device?)-> output device ----All preprocessing
(dithering/correction/etc) done with Reggae filters
