Syntax

Printing a PDF file Hide the details

<Result> = iPrintPDF(<Name of PDF file> [, <Password> [, <Sizing> [, <List of pages>]]])

<Result>: Boolean

True if printed successfully,
False otherwise. To get more details on the error, use ErrorInfo with the errMessage constant.
Caution: Printing is asynchronous: When the function is called, the print settings window appears. It is not possible to find out if the printout has been cancelled or if an error occurred during printing.

<Name of PDF file>: Character string

Name and path of PDF file to print. This parameter can correspond to a full path or a path relative to the current directory (returned by fCurrentDir). This parameter is case-sensitive.
Reminder: On iPhone/iPad, an application has the rights to write into its installation directory or into one of its subdirectories.

<Password>: Character string

Password for opening the PDF file,
Empty string ("") if the file has no password.
This parameter is not available.

<Sizing>: Integer constant

Print size:
iHomothetic Homothetic enlargement or reduction of the PDF document pages to adapt them to the output format, ignoring physical margins.
This constant corresponds to the option "Fit to paper size" available in PDF printing software.
iHomotheticNoEnlargement Homothetic reduction of the PDF document pages to adapt them to the output format, ignoring physical margins. Pages with a smaller format keep their format and are centered.
