Adobe Reader da linea di comando.

E' possibile mandare in esecuzione Adobe Reader da linea di comando sfruttando alcuni parametri purtroppo non documentati.
Alcuni fra questi permettono anche di stampare un documento pdf senza visualizzare l'interfaccia del Reader o di Acrobat.
Ecco cosa ho trovato cercando in rete:

[From the DEVFAQ]
AcroRd32.exe filename - Executes the Reader and displays a file.
Other options for the command line are:
AcroRd32.exe /p filename - Executes the Reader and prints a file.
AcroRd32.exe /t path printername drivername portname - Initiates Acrobat Reader, prints a file while suppressing the Acrobat print dialog box, then terminates Reader.
The four parameters of the /t option evaluate to path, printername, drivername, and portname (all strings).
printername - The name of your printer.
drivername - Your printer driver's name. Whatever appears in the Driver Used
box when you view your printer's properties.
portname - The printer's port. portname cannot contain any "/" characters;
if it does, output is routed to the default port for that printer.
If using Acrobat, substitute Acrobat.exe in place of AcroRd32.exe in the command lines.

Option meaning:
/n Launch a separate instance of the Acrobat application, even if one is
currently open.
/s Open Acrobat, suppressing the splash screen.
/o Open Acrobat, suppressing the open file dialog.
/h Open Acrobat in hidden mode.
