> With LaserJet, trays PostScript instruction are
> for Tray 1 : /MediaPosition 1
> for Tray 2 : /MediaPosition 2
>
> With Xerox :
> for Tray 1 : (tray1) xerox$MediaInputTray
> for Tray 2 : (tray2) xerox$MediaInputTray
> Here is an extract of my IF file (Intermediate Format) for LaserJet :
> PS file for LaserJet :
> Page 1 :
> %FOPBeginSetPageDevice
> <<
> /PageSize [595 842]
> /MediaPosition 1
> /ImagingBBox null
> >> setpagedevice
> %FOPEndSetPageDevice
> Page 2 :
> %FOPBeginSetPageDevice
> <<
> /PageSize [595 842]
> /MediaPosition 2
> /ImagingBBox null
> >> setpagedevice
> %FOPEndSetPageDevice
> PS file for Xerox :
> Page 1 :
> %FOPBeginSetPageDevice
> <<
> /PageSize [595 842]
> (tray1) xerox$MediaInputTray <===== correct/ImagingBBox null
> >> setpagedevice
> %FOPEndSetPageDevice
> Page 2 :
> %FOPBeginSetPageDevice
> <<
> /PageSize [595 842]
> (tray1) xerox$MediaInputTray <===== incorrect
> (tray2) xerox$MediaInputTray <===== only this line is correct
> /ImagingBBox null
> >> setpagedevice
> %FOPEndSetPageDevice
> I have analysed the fop source code.
> In fact, Fop use a key/Value HashTable and all new key/value are cumulative.
>
> With LaserJet
> Page 1 : key=/MediaPosition and value=1 => Fop write in PostScript :
> “/MediaPosition 1”
> Page 2 : key=/MediaPosition and value=2 => Fop write in PostScript :
> “/MediaPosition 2”
> With Xerox :
> Page 1 : key=(tray1) and value=xerox$MediaInputTray => Fop write in
> PostScript : “(tray1) xerox$MediaInputTray”
> Page 2 : key=(tray2) and value=xerox$MediaInputTray => Fop write in
> PostScript all keys/values : “(tray1) xerox$MediaInputTray” + “(tray2)
> xerox$MediaInputTray”
