\section{\class{wxPrintData}}\label{wxprintdata}

This class holds a variety of information related to printers and
printer device contexts. This class is used to create a wxPrinterDC
and a wxPostScriptDC. It is also used as a data member of wxPrintDialogData
and wxPageSetupDialogData, as part of the mechanism for transferring data
between the print dialogs and the application.

Default constructor.

\func{}{wxPrintData}{\param{const wxPrintData\&}{ data}}

Copy constructor.


\membersection{wxPrintData::\destruct{wxPrintData}}\label{wxprintdatadtor}

\func{}{\destruct{wxPrintData}}{\void}

Destructor.


\membersection{wxPrintData::GetCollate}\label{wxprintdatagetcollate}

\constfunc{bool}{GetCollate}{\void}

Returns true if collation is on.


\membersection{wxPrintData::GetBin}\label{wxprintdatagetbin}

\constfunc{wxPrintBin}{GetBin}{\void}

Returns the current bin (papersource). By default, the system is left to select
the bin (\texttt{wxPRINTBIN\_DEFAULT} is returned).

See \helpref{SetBin()}{wxprintdatasetbin} for the full list of bin values.


\membersection{wxPrintData::GetColour}\label{wxprintdatagetcolour}

\constfunc{bool}{GetColour}{\void}

Returns true if colour printing is on.


\membersection{wxPrintData::GetDuplex}\label{wxprintdatagetduplex}

\constfunc{wxDuplexMode}{GetDuplex}{\void}

Returns the duplex mode. One of wxDUPLEX\_SIMPLEX, wxDUPLEX\_HORIZONTAL, wxDUPLEX\_VERTICAL.


\membersection{wxPrintData::GetNoCopies}\label{wxprintdatagetnocopies}

\constfunc{int}{GetNoCopies}{\void}

Returns the number of copies requested by the user.


\membersection{wxPrintData::GetOrientation}\label{wxprintdatagetorientation}

\constfunc{int}{GetOrientation}{\void}

Gets the orientation. This can be wxLANDSCAPE or wxPORTRAIT.


\membersection{wxPrintData::GetPaperId}\label{wxprintdatagetpaperid}

\func{void}{SetPaperId}{\param{wxPaperSize}{ paperId}}

\index{wxPaperSize}Sets the paper id. This indicates the type of paper to be used. For a mapping between
paper id, paper size and string name, see wxPrintPaperDatabase in {\tt paper.h} (not yet documented).

{\it paperId} can be one of:
