| class CPrinterDevice : public CGraphicsDevice |
Printer graphics device interface.
This abstract class represents a physical graphics device that is used for printing.
This class is used to:
set and get the page specification
map between the co-ordinates of the printed page (in twips) and the co-ordinates of the image device (in pixels)
get and set the printer model entry
create and delete a printer control.
A printer driver is defined in terms of a printer device and a printer control. A printer device can own either a single or no printer control. The control determines the progress and termination of the print job and is responsible for producing output.

| void | CreateControlL | ( | CPrinterPort * | aPrinterPort | ) | [pure virtual] |
Creates a printer control.
The printer control is an instance of a CPrinterControl derived class; it is assigned to this printer device's iControl member.
Note that this function is called by CPrintSetup::StartPrintL().
| CPrinterPort * aPrinterPort | Pointer to an instance of a printer port. |
| TPageSpec | CurrentPageSpecInTwips | ( | ) | const [inline] |
Gets the current page specification in twips.
The current page specification, in twips.
| void | ExternalizePropertiesL | ( | RWriteStream & | ) | const [inline, virtual] |
Externalizes printer properties to the store.
The default implementation is empty.
| RWriteStream & |
| void | InternalizePropertiesL | ( | RReadStream & | ) | [inline, virtual] |
Externalizes printer properties to the store.
The default implementation is empty.
| RReadStream & |
| TPrinterModelEntry | Model | ( | ) | const [pure virtual] |
Gets the printer model entry.
The printer model entry.
| IMPORT_C void | SelectPageSpecInTwips | ( | const TPageSpec & | aPageSpec | ) | [virtual] |
Sets the page specification in twips.
| const TPageSpec & aPageSpec | The page specification in twips. |
| TInt | SetModel | ( | const TPrinterModelHeader & | aModel, |
| CStreamStore & | aStore | |||
| ) | [pure virtual] | |||
Sets the printer model header and the store.
KErrNone if successful; otherwise, another of the system-wide error codes.
| const TPrinterModelHeader & aModel | The printer model header. |
| CStreamStore & aStore | The store. |
| CPrinterControl * | iControl |
The printer control.
This may be NULL. If implemented, it provides control over the print operation.
| TPageSpec | iCurrentPageSpecInTwips | [protected] |
Current page specification in twips.
