      实例1：文字串定位折行打印在口岸联检部门中应用非常广泛。下述例子是用CmdPrnt1的Click事件代码实现了对文字串定位折行打印： <PRE>Private Sub CmdPrnt1_Click()
Dim str As String, str1 As String ,txt As String
Dim strx As Integer, stry As Integer,i As Integer
strx = 200
stry = 0 
txt = Space(20) + "中国出入境检验检疫标准目录检索STEMS 2000"
Printer.FontName = "黑体"
dd = prnt11(strx, stry, 10, txt, 50)
stry = stry + rowlab * 240
Printer.Line (0, stry)-(9000, stry)
Printer.FontName = "宋体"
txt = "标准号：" + Space(2) + Trim(Text1) + Space(3) + 
"发布日期：" + Trim(Text4) + Space(3) + "实施日期：" 
+ Trim(Text6) + Space(3) + "修定日期：" + Trim(Text5) '+ Chr(13)
stry = stry + 240
dd = prnt11(strx, stry, 10, txt, 70)
stry = stry + rowlab * 240
txt = "代替标准："
dd = prnt11(strx, stry, 10, txt, 10)
dd = prnt11(strx + 1000, stry, 10, Trim(Text7), 60)
stry = stry + rowlab * 240
txt = "标准名称："
dd = prnt11(strx, stry, 10, txt, 10)
dd = prnt11(strx + 1000, stry, 10, Trim(Text4), 38)
stry = stry + rowlab * 240
txt = "英文名称："
dd = prnt11(strx, stry, 10, txt, 10)
dd = prnt11(strx + 1000, stry, 10, Text5, 72)
Printer.EndDoc
End Sub
</PRE>
      <P class=sfont><FONT color=#ffffff>----</FONT> 注： Prnt11函数原形：prnt11(X As 
      Integer, Y As Integer, Font As Single, Txt As String, Val As 
      Integer)，其各参数含义如下： 
      <P class=sfont><FONT color=#ffffff>----</FONT> X、Y为待打印字符串左上角起始座标； 
      <P class=sfont><FONT color=#ffffff>----</FONT> Font为字体大小； 
      <P class=sfont><FONT color=#ffffff>----</FONT> Txt为待打印字符串； 
      <P class=sfont><FONT color=#ffffff>----</FONT> Val为字符串打印折行长度。 
      <P class=sfont><FONT color=#ffffff>----</FONT> 
      实例2：直接打印表格式窗体显示的多记录多字段，往往因某些字段的字节太多而造成纸张宽度不足。以下CmdPrnt2的Click事件中的代码，实现了对上述MSFGrid1表格记录的打印： 
<PRE>Private Sub CmdPrnt2_Click()
Dim fnt As Single
Dim pp As Integer
Dim stry As Integer, strx As Integer
Dim stry1 As Integer, 
strx1 As Integer, linw As Integer
Dim page1 As Integer, p As Integer,
 gridrow As Integer, ii As Integer
p = 0
ii = 1  'ii记录MSFGRID1表格同一记录内字段最大打印行
pp = 0 '开始页码
ss$ = "中国出入境检验检疫标准目录检索STEMS 2000" ' 表头
Static a(4) As Integer
kan = 0
a(2) = 1680 
a(3) = 2800
a(4) = 5300
page1 = 46 '定义每页行数
  strx = 200
  strx1 = 200
  stry = 1400
  stry1 = 1400
  linw = 240 '定义行宽
  fnt = 10 '定义字体大小
  For i = 2 To 4 
      kan = kan + a(i)
  Next
  gridrow = Datdatact1.Recordset.RecordCount
  If gridrow = 0 Then
     MsgBox "无满足条件记录打印！"
     Exit Sub
 End If
  Printer.FontName = "黑体"
  dd = prnt11(3300, 700, fnt, ss$, 26) '打印标题
  dd = prnt11(500, stry - 250, fnt, "标准号", 26)
  dd = prnt11(2690, stry - 250, fnt, "标准名称", 26) 
  dd = prnt11(6690, stry - 250, fnt, "英文名称", 26) 
  Printer.Line (strx - 20, stry - 30)-(10460, stry - 30) 
  Printer.FontName = "宋体"
  For j = 1 To gridrow  '打印gridrow条记录
       MSFGrid1.Row = j
       strx = strx1
       For i = 2 To 4 '假设只打印2-3 列
         MSFGrid1.Col = i
         dd = prnt11(strx, stry, fnt,
 MSFGrid1.Text, IIf(i = 3, 13, 55))
         If ii &lt; rowlab Then 
'ii记录同一记录内字段最大打印行
           ii = rowlab
         End If
         strx = strx + a(i)
       Next
       p = p + ii 
       rowlab = ii
       ii = 1 '重新初始化
       If p &gt; page1 Then
           p = 0
           strx = strx1
           For n = 2 To 4
             strx = strx + a(n)
           Next
           pp = pp + 1
           stry = stry + rowlab * linw
           foot$ = "第" + CStr(pp) + "页"
           dd = prnt11(strx / 2, stry + 3 * linw, 10, foot$, 26)
           stry = stry1
           Printer.NewPage
           Printer.FontName = "黑体"
           dd = prnt11(3300, 700, fnt, ss$, 26)
           dd = prnt11(500, stry - 250, fnt, "标准号", 26) 
           dd = prnt11(2690, stry - 250, fnt, "标准名称", 26)
           dd = prnt11(6690, stry - 250, fnt, "英文名称", 26)
           Printer.Line (-20, stry - 30)-(10460, stry - 30)
           '打印起始线
           Printer.FontName = "宋体"
           strx = strx1
         Else
           stry = stry + rowlab * linw 
         End If
      Next
      If p &lt; page1 Then 
          For p = 0 To page1 + 1
             strx = strx1
          Next
      End If
      strx = strx1
      For n = 2 To 4
          strx = strx + a(n)
      Next
      pp = pp + 1
      foot$ = "第" + CStr(pp) + "页"
      dd = prnt11(strx / 2, stry + 3 * linw, 10, foot$, 26)
      Printer.EndDoc
  End Sub
