4、打印表头,我将表头的各个部分划成了几部分,如我的凭证打印的地方,我就划成了五部分,每部分按占百分比多少计算。如编制单位就占页面宽度的40%等

procedure TF_printpreview.printpageheader(pageheader: Tstrings);
var
Headrect:Trect;
count:integer;
begin
pp_pz.Printer.Canvas.Font.Name:=''''宋体'''';
pp_pz.Printer.Canvas.Font.Color:=clblack;
pp_pz.Printer.Canvas.Font.Size:=9;
pp_pz.Printer.Canvas.Font.Style:=[];
gettextinfo;
Amountprint:=Amountprint round(0.8*textheight);//当前逻辑尺的位置
for count:=0 to pageheader.Count-1 do
begin
case count of
0:
HeadRect:=Rect(round(pp_pz.Printer.PageSet.LeftMargin),Amountprint,round(pp_pz.Printer.PageSet.LeftMargin round(0.4*(pp_pz.Printer.PageWidth))),Amountprint textheight);//编制单位比例
1:
HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right round(0.16*(pp_pz.Printer.PageWidth)),Amountprint textheight);//凭证日期比例
2:
HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right round(0.14*(pp_pz.Printer.PageWidth)),Amountprint textheight);//帐套号比例
3:
HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right round(0.2*(pp_pz.Printer.PageWidth)),Amountprint textheight);//凭证号比例
4:
HeadRect:=Rect(headrect.Right,Amountprint,headrect.Right round(0.1*(pp_pz.Printer.PageWidth)),Amountprint textheight);//分页数号比例
end;
pp_pz.Printer.Canvas.TextOut(Headrect.left,headrect.top,pageheader[count]);
end;
end;

5、打印表格头

procedure TF_mxzprint.printdetailheader(detailheader: Tstrings);
var
drect,srect,jrect:Trect;
begin
pp_pz.Printer.Canvas.Font.Name:=''''宋体'''';
pp_pz.Printer.Canvas.Font.Color:=clblack;
pp_pz.Printer.Canvas.Font.Size:=9;
pp_pz.Printer.Canvas.Font.Style:=[];
gettextinfo;
Amountprint:=Amountprint textheight;
pp_pz.Printer.Canvas.Font.Size:=11;
drect:=rect(PageRect.Left,Amountprint,PageRect.Left round(0.3*(PageRect.Right-PageRect.Left)),Amountprint 2*textheight);
drawtext(pp_pz.Printer.Canvas.handle,pchar(''''摘 要''''),length(''''摘 要''''),drect,DT_center or DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);
addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);

drect:=rect(drect.right,drect.Top,drect.right round(0.4*(PageRect.Right-PageRect.Left)),srect.Bottom);
drawtext(pp_pz.Printer.Canvas.handle,pchar(''''科目名称''''),length(''''科目名称''''),drect,DT_center or DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);
addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);
drect:=rect(drect.right,drect.Top,drect.right round(0.15*(PageRect.Right-PageRect.Left)),srect.Bottom);
drawtext(pp_pz.Printer.Canvas.handle,pchar(''''借方金额''''),length(''''借方金额''''),drect,DT_center or DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);

addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom]);
drect:=rect(drect.right,drect.Top,drect.right round(0.15*(PageRect.Right-PageRect.Left)),srect.Bottom);
addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom,drect.left,drect.top]);
drawtext(pp_pz.Printer.Canvas.handle,pchar(''''贷方金额''''),length(''''贷方金额''''),drect,DT_center or DT_WORDBREAK or DT_VCENTER or DT_SINGLELINE);

addpolyline([drect.left,drect.top,drect.right,drect.top,drect.right,drect.bottom,drect.left,drect.bottom]);
Amountprint:=amountprint drect.Bottom-drect.Top;// textheight;
end;

5、打印表格内容

(与上面相似,代码太多,略。。。)

6、打印汇总栏内容(代码较多,而且也相似,略)

7、执行打印功能

pp_pz.Printer.BeginDoc;
依次打印标题、打印、表头等

PolyPolyline(pp_pz.Printer.Canvas.Handle,PolyPolyPoints.List^,PolyLengths.List^,PolyLengths.Count); pp_pz.Printer.EndDoc;

关键:就两个函数PolyPolyline和DrawText而已!

请注意,我这是连载,我发现我最后一贴看的人比较多,可光看这篇基本上看不出什么来的。管理员没有发表我的第一篇,我现在把第一篇放到了连(二)里面去了,所以大家不要找连载(一)了!由于时间比较忙,所以有一部分朋友要求要源码还没来的及整理,但我一整理出来我就会发过去的,谢谢大家!

好了,如果大家需要源码可以向我索取,yczyk@163.com
