	`procedure OnPrintSettings(const browser: ICefBrowser; const settings: ICefPrintSettings; getDefaults: boolean);`
Synchronize \|settings\| with client state. If \|get_defaults\| is true (1) then populate \|settings\| with the default print settings. Do not keep a reference to \|settings\| outside of this callback.

	`procedure OnPrintDialog(const browser: ICefBrowser; hasSelection: boolean; const callback: ICefPrintDialogCallback; var aResult: boolean);`
Show the print dialog. Execute \|callback\| once the dialog is dismissed. Return true (1) if the dialog will be displayed or false (0) to cancel the printing immediately.

	`procedure OnPrintJob(const browser: ICefBrowser; const documentName, PDFFilePath: ustring; const callback: ICefPrintJobCallback; var aResult: boolean);`
Send the print job to the printer. Execute \|callback\| once the job is completed. Return true (1) if the job will proceed or false (0) to cancel the job immediately.

	`procedure OnPrintReset(const browser: ICefBrowser);`
Reset client state related to printing.

	`procedure GetPDFPaperSize(const browser: ICefBrowser; deviceUnitsPerInch: integer; var aResult: TCefSize);`
Return the PDF paper size in device units. Used in combination with ICefBrowserHost.PrintToPdf().

	`procedure RemoveReferences;`
Custom procedure to clear all references.
