How to do silent batch printing
eDocPrinter PDF Pro supports silent printing by controlling
parameters in Destination property page. Combined with Windows Explorer [Print]
function, user can do silent batch printing without any extra component or any
extra cost.
For doing silent printing, users have to change the SaveAs Mode
first. After selecting the proper default directory and processing condition
when the file exists, silent printing shall work well now.

Turning on the option [Launch PostAction from New Process] will
enable the pending actions to be attached in a new process instead of a thread
of current application. Since in batch printing, applications may be close
before printing job finished. Hence it would be better to check on this option
before doing batch printing.
After setting the silent mode printing and eDocPrinter as
default printer, it becomes easier for doing batch printing. Users can select
the files from Windows Explorer and right click to select [Print] to print all
the files selected. Be sure only document types supporting OLE printing can
support this way of printing, e.g., Office application files (.doc, .xls, .ppt,
.txt ...).
For batch printing of office application files, we suggest users
to launch the office application first. By this, those applications (Word,
Excel, ...) supporting single instance will not be restarted as new processes
when opening multiple documents. This reduces the printing time a lot since
launching such applications consumes a lot of time than printing the documents
themselves.
