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
