UNIDRVINFO structure (prntfont.h)
The UNIDRVINFO structure is used to specify printer-specific information within Unidrv font metrics files (.ufm files).
Syntax
typedef struct _UNIDRVINFO {
DWORD dwSize;
DWORD flGenFlags;
WORD wType;
WORD fCaps;
WORD wXRes;
WORD wYRes;
short sYAdjust;
short sYMoved;
WORD wPrivateData;
short sShift;
INVOC SelectFont;
INVOC UnSelectFont;
WORD wReserved[4];
} UNIDRVINFO, *PUNIDRVINFO;
Members
dwSize
Specifies the size, in bytes, of the UNIDRVINFO structure.
flGenFlags
Contains one or more bit flags describing font characteristics. The following flags are defined:
Flag | Definition |
---|---|
UFM_CART | The font is contained in a cartridge. |
UFM_SCALABLE | The font is scalable. |
UFM_SOFT | The font is a soft font, requiring downloading. |
wType
Contains an integer constant describing the font type. The following constants are defined:
Constant | Definition |
---|---|
DF_TYPE_CAPSL | Canon CAPSL scalable font |
DF_TYPE_HPINTELLIFONT | HP Intellifont font |
DF_TYPE_OEM1 | OEM-supplied scalable font |
DF_TYPE_OEM2 | OEM-supplied scalable font |
DF_TYPE_PST1 | Lexmark PPDS scalable font |
DF_TYPE_TRUETYPE | HP PCLETTO font for LJ4 printers |
fCaps
Contains one or more bit flags identifying limitations on the capabilities provided by a device font. The following flags are defined:
Flag | Definition |
---|---|
DF_BKSP_OK | If set, a single backspace character can move the cursor to the beginning of the overstrike region. If not set, an x-movement cursor command must be sent. (Used only if MTYPE_PAIRED is specified for the character's TRANSDATA structure in MAPTABLE. Otherwise ignored.) |
DF_NO_BOLD | The device font cannot be bolded using underline simulation. |
DF_NO_DOUBLE_UNDERLINE | The device font cannot be double-underlined using double-underline simulation. |
DF_NO_STRIKETHRU | The device font cannot be struck through using strike-through simulation. |
DF_NOITALIC | The device font cannot be italicized using italic simulation. |
DF_NOUNDER | The device font cannot be underlined using underline simulation. |
DF_XM_CR | Unidrv must send a carriage return command after each line of text. |
wXRes
Specifies the font's x-resolution.
wYRes
Specifies the font's y-resolution.
sYAdjust
Specifies the amount of vertical adjustment required before output of double-height characters on dot-matrix printers.
sYMoved
Specifies the amount of vertical cursor movement that results when a double-height character is printed on a dot-matrix printer.
wPrivateData
Can be used for printer-specific information such as, for example, HP DeskJet permutations.
sShift
Specifies the number of pixels by which each character must be shifted. Used for the Microsoft Z1a cartridge.
SelectFont
Is an INVOC structure containing the printer's font selection command.
UnSelectFont
Is an INVOC structure containing the printer's font deselection command.
wReserved[4]
Not used.
Remarks
A .ufm (Unidrv Font Metrics) file's UNIDRVINFO structure is accessed by a pointer in the file's UNIFM_HDR structure.
