Member Function Documentation

AbortDoc()

int owl::TPrintDC::AbortDoc ( )

inline

Aborts the current print job on this printer and erases everything drawn since the last call to StartDoc.

AbortDoc calls the user-defined function set with TPrintDC::SetAbortProc to abort a print job because of error or user intervention. TPrintDC::EndDoc should be used to terminate a successfully completed print job. If successful, AbortDoc returns a positive or zero value; otherwise a negative value is returned.

BandInfo()

int owl::TPrintDC::BandInfo ( TBandInfo & bandInfo )

inline

Retrieves information about the banding capabilities of this device, and copies it to the given bandInfo structure.

If successful, returns a positive value; otherwise the return value is a system error code.

Definition at line 3728 of file dc.h.

References Escape().

EndDoc()

int owl::TPrintDC::EndDoc ( )

inline

Ends the current print job on this printer.

EndDoc should be called immediately after a successfully completed print job. TPrintDC::AbortDoc should be used to terminate a print job because of error or user intervention. If successful, EndDoc returns a positive or zero value; otherwise a negative value is returned.

Escape()

int owl::TPrintDC::Escape ( int esc, int count = 0, const void * inData = nullptr, void * outData = nullptr )

inline

Allows applications to access the capabilities of a particular device that are not directly available through the GDI of this DC.

The Escape call is specified by setting a mnemonic value in the escape argument. In Win32 the use of Escape with certain escape values has been replaced by specific functions. The names of these new functions are based on the corresponding escape mnemonic, as shown in the following table:

• ABORTDOC Superseded by TPrintDC_AbortDoc in Win32.
• BANDINFO Obsolete in Win32. Because all printer drivers for Windows version 3.1 and later set the text flag in every band, this escape is useful only for older printer drivers.
• BEGIN_PATH No changes for Win32. This escape is specific to PostScript printers.
• CLIP_TO_PATH No changes for Win32. This escape is specific to PostScript printers.
• DEVICEDATA Superseded in Win32. Applications should use the PASSTHROUGH escape to achieve the same functionality.
• DRAFTMODE Superseded in Win32. Applications can achieve the same functionality by setting the dmPrintQuality member of the DEVMODE structure to DMRES_DRAFT and passing this structure to the CreateDC function.
• DRAWPATTERNRECT No changes for Win32.
• ENABLEDUPLEX Superseded in Win32. Applications can achieve the same functionality by setting the dmDuplex member of the DEVMODE structure and passing this structure to the CreateDC function.
• ENABLEPAIRKERNING No changes for Win32.
• ENABLERELATIVEWIDTHS No changes for Win32.
• ENDDOC Superseded by TPrintDC_EndDoc in Win32.
• END_PATH No changes for Win32. This escape is specific to PostScript printers.
• ENUMPAPERBINS Superseded in Win32. Applications can use TPrintDC::DeviceCapabilities to achieve the same functionality.
• ENUMPAPERMETRICS Superseded in Win32. Applications can use TPrintDC::DeviceCapabilities to achieve the same functionality.
• EPSPRINTING No changes for Win32. This escape is specific to PostScript printers.
• EXT_DEVICE_CAPS Superseded in Win32. Applications can use TDC::GetDeviceCaps to achieve the same functionality. This escape is specific to PostScript printers.
• EXTTEXTOUT Superseded in Win32. Applications can use TDC::ExtTextOut to achieve the same functionality. This escape is not supported by the version 3.1 PCL driver.
• FLUSHOUTPUT Removed for Win32.
• GETCOLORTABLE Removed for Win32.
• GETEXTENDEDTEXTMETRICS No changes for Win32. Support for this escape might change in future versions of Windows.
• GETEXTENTTABLE Superseded in Win32. Applications can use GetCharWidth to achieve the same functionality. This escape is not supported by the version 3.1 PCL or PostScript drivers.
• GETFACENAME No changes for Win32. This escape is specific to PostScript printers.
• GETPAIRKERNTABLE No changes for Win32.
• GETPHYSPAGESIZE No changes for Win32. Support for this escape might change in future versions of Windows.
• GETPRINTINGOFFSET No changes for Win32. Support for this escape might change in future versions of Windows.
• GETSCALINGFACTOR No changes for Win32. Support for this escape might change in future versions of Windows.
• GETSETPAPERBINS Superseded in Win32. Applications can achieve the same functionality by calling TPrintDC::DeviceCapabilities to find the number of paper bins, calling ::ExtDeviceMode to find the current bin, and then setting the dmDefaultSource member of the DEVMODE structure and passing this structure to the CreateDC function. GETSETPAPERBINS changes the paper bin only for the current device context. A new device context will use the system-default paper bin until the bin is explicitly changed for that device context.
• GETSETPAPERMETRICS Obsolete in Win32. Applications can use TPrintDC::DeviceCapabilities and ::ExtDeviceMode to achieve the same functionality.
• GETSETPAPERORIENT Obsolete in Win32. Applications can achieve the same functionality by setting the dmOrientation member of the DEVMODE structure and passing this structure to the CreateDC function. This escape is not supported by the Windows 3.1 PCL driver.
• GETSETSCREENPARAMS No changes for Win32.
• GETTECHNOLOGY No changes for Win32. Support for this escape might change in future versions of Windows. This escape is not supported by the Windows 3.1 PCL driver.

• SET_ARC_DIRECTION No changes for Win32. This escape is specific to PostScript printers.
• SET_BACKGROUND_COLOR No changes for Win32. Applications should use SetBkColor instead of this escape. Support for this escape might change in future versions of Windows.
• SET_BOUNDS No changes for Win32. This escape is specific to PostScript printers.
• SETCOLORTABLE No changes for Win32. Support for this escape might change in future versions of Windows.
• SETCOPYCOUNT Superseded in Win32. An application should call TPrintDC::DeviceCapabilities, specifying DC_COPIES for the capability parameter, to find the maximum number of copies the device can make. Then the application can set the number of copies by passing to the CreateDC function a pointer to the DEVMODE structure.
• SETKERNTRACK No changes for Win32.
• SETLINECAP No changes for Win32. This escape is specific to PostScript printers.
• SETLINEJOIN No changes for Win32. This escape is specific to PostScript printers.

• SET_SPREAD No changes for Win32.
• STARTDOC Superseded in Win32. Applications should call StartDoc instead of this escape.
• TRANSFORM_CTM No changes for Win32. This escape is specific to PostScript printers.

Escape calls are translated and sent to the printer device driver. The inData buffer lets you supply any data needed for the escape. You must set count to the size (in bytes) of the inData buffer. If no input data is required, inData and count should be set to the default value of 0. Similarly, you must supply an outData buffer for those Escape calls that retrieve data. If the escape does not supply output, set outData to the default value of 0.

Definition at line 3528 of file dc.h.

NextBand()

int owl::TPrintDC::NextBand ( TRect & rect )

inline

Tells this printer's device driver that the application has finished writing to a band.

The device driver sends the completed band to the Print Manager and copies the coordinates of the next band in the rectangle specified by rect. If successful, NextBand returns a positive value; otherwise the return value is a system error code. Possible failure values are listed below:

• SP_ERROR General error.
• SP_APPABORT Job terminated because the application's print-canceling function returned 0.
• SP_USERABORT User terminated the job.
• SP_OUTOFDISK Insufficient disk space for spooling.
