楼主lonelystarcn（虫虫）2002-06-24 19:35:16 在 VB / 基础类提问

我设计软件时生成报表统一是用VB中的报表,打印单据时都是打印窗体.
但现在客户的打印机改成针式打印机,而且纸张是连纸(也就是不分页的纸,好长好长,打到哪撕到哪),这样打印报表时在表头和表尾都会留下好长的空白,更要命的是最后一页如果记录数还不满一页时留下的空白更大,而打印据时,每打印一张小小的单据都占据一张A4纸张大小,浪费更大,
请问我该如何解决这个问题??????????????????????????????????????????? 问题点数：100、回复次数：17Top

改打印的程序，用行打印Top

就是说用Printer对像来打印，
或是设置打印纸的大小，也可能搞定，我没试过Top

但我现在的报表太多了,有20张,怎么改?时间不够,报表中能有不分页打印吗?Top

同意楼上,printer比较灵活,但有些麻烦Top

5 楼lonelystarcn（虫虫）回复于 2002-06-24 19:46:12 得分 0

我现在的想法是:
当需要打印报表时用Printer对象将纸张大小改为A4,毕竟这浪费一点没什么大关系,
当需要打印单据时用Printer对象将纸张大小自定义大小成单据大小,
请问这样可以吗?
谁能给出两功能的代码????
我现在可是在出差现场给客户改啊!!Top

使用下面的代码打印，里面有打印纸的设置
With ComDialog1
.CancelError = True
.flags = cdlPDReturnDC + cdlPDNoPageNums + &H100000
Me.ActiveForm.RTBox1.SelLength = 0
.ShowPrinter

那么如何定义长宽成20cm*10cm呢?Top

DEVMODE
The DEVMODE data structure contains information about the device initialization and environment of a printer.

typedef struct _devicemode { // dvmd
BCHAR dmDeviceName[CCHDEVICENAME];
WORD dmSpecVersion;
WORD dmDriverVersion;
WORD dmSize;
WORD dmDriverExtra;
DWORD dmFields;
union {
struct {
short dmOrientation;
short dmPaperSize;
short dmPaperLength;
short dmPaperWidth;
};
POINTL dmPosition;
};
short dmScale;
short dmCopies;
short dmDefaultSource;
short dmPrintQuality;
short dmColor;
short dmDuplex;
short dmYResolution;
short dmTTOption;
short dmCollate;
BCHAR dmFormName[CCHFORMNAME];
WORD dmLogPixels;
DWORD dmBitsPerPel;
DWORD dmPelsWidth;
DWORD dmPelsHeight;
DWORD dmDisplayFlags;
DWORD dmDisplayFrequency;
#if(WINVER >= 0x0400)
DWORD dmICMMethod;
DWORD dmICMIntent;
DWORD dmMediaType;
DWORD dmDitherType;
DWORD dmReserved1;
DWORD dmReserved2;
#if (WINVER >= 0x0500) || (_WIN32_WINNT >= 0x0400)
DWORD dmPanningWidth;
DWORD dmPanningHeight;
#endif
#endif /* WINVER >= 0x0400 */
} DEVMODE;

Members
dmDeviceName
Specifies the the "friendly" name of the printer; for example, "PCL/HP LaserJet" in the case of PCL/HP LaserJet®. This string is unique among device drivers. Note that this name may be truncated to fit in the dmDeviceName array.
dmSpecVersion
Specifies the version number of the initialization data specification on which the structure is based.
dmDriverVersion
Specifies the printer driver version number assigned by the printer driver developer.
dmSize
Specifies the size, in bytes, of the DEVMODE structure, not including any private driver-specific data that might follow the structure's public members. Set this member to sizeof(DEVMODE) to indicate the version of the DEVMODE structure being used.
dmDriverExtra
Contains the number of bytes of private driver-data that follow this structure. If a device driver does not use device-specific information, set this member to zero.
dmFields
A set of bit flags that specify whether certain members of the DEVMODE structure have been initialized. If a field is initialized, its corresponding bit flag is set, otherwise the bit flag is clear. A printer driver supports only those DEVMODE structure members that are appropriate for the printer technology.
The following bit flags are defined, and are listed here with the corresponding structure members: Value Structure Member
DM_ORIENTATION dmOrientation
DM_PAPERSIZE dmPaperSize
DM_PAPERLENGTH dmPaperLength
DM_PAPERWIDTH dmPaperWidth
DM_POSITION dmPosition
DM_SCALE dmScale
DM_COPIES dmCopies
DM_DEFAULTSOURCE dmDefaultSource
DM_PRINTQUALITY dmPrintQuality
DM_COLOR dmColor
DM_DUPLEX dmDuplex
DM_YRESOLUTION dmYResolution
DM_TTOPTION dmTTOption
DM_COLLATE dmCollate
DM_FORMNAME dmFormName
DM_LOGPIXELS dmLogPixels
DM_BITSPERPEL dmBitsPerPel
DM_PELSWIDTH dmPelsWidth
DM_PELSHEIGHT dmPelsHeight
DM_DISPLAYFLAGS dmDisplayFlags
DM_DISPLAYFREQUENCY dmDisplayFrequency
DM_ICMMETHOD dmICMMethod
DM_ICMINTENT dmICMIntent
DM_MEDIATYPE dmMediaType
DM_DITHERTYPE dmDitherType
DM_PANNINGWIDTH Windows NT 5.0 and later: dmPanningWidth
DM_PANNINGHEIGHT Windows NT 5.0 and later: dmPanningHeight

dmOrientation
For printer devices only, selects the orientation of the paper. This member can be either DMORIENT_PORTRAIT (1) or DMORIENT_LANDSCAPE (2).
dmPaperSize
For printer devices only, selects the size of the paper to print on. This member can be set to zero if the length and width of the paper are both set by the dmPaperLength and dmPaperWidth members. Otherwise, the dmPaperSize member can be set to one of the following predefined values: Value Meaning
DMPAPER_LETTER Letter, 8 1/2- by 11-inches

dmPaperLength
For printer devices only, overrides the length of the paper specified by the dmPaperSize member, either for custom paper sizes or for devices such as dot-matrix printers, which can print on a page of arbitrary length. These values, along with all other values in this structure that specify a physical length, are in tenths of a millimeter.
dmPaperWidth
For printer devices only, overrides the width of the paper specified by the dmPaperSize member.
dmPosition
Windows NT 5.0 and later, Windows 98: For display devices only, a POINTL structure that indicates the positional coordinates of the display device in reference to the desktop area. The primary display device is always located at coordinates (0,0).

嘿嘿.....今天终于用了一个笨方法解决了该问题,
在控制面板的打印机属性中设置纸张大小成单据大小,
然后设置各报表的顶边界为0,底边界为40,标头提到报表标题栏中
这样打印出来的报表即使分页了也看不出来,
谢谢所有这此留言的高手们.
