我挣扎着爬了爱普生“ESC / POS”打印机打印条码(用Delphi)和想要测试如果打印机没有故障。你知道我在哪里可以找到一个程序打印在“ESC / POS”条形码?我想作为最后手段OPOS的计划也将确定。
此外,演示德尔福计划,作品也将被罚款。所有德尔福片断我至今没有工作。
我使用的打印机是一个Epson TM-L60II
解决方案
我已经写在Delphi 5的TMT88的一个完整的测试程序,但源是升技大的这里,所以这里是条形码位
请注意,当从完整的对象一些VARS /功能可能会丢失其片段
要获得条形码字符
{**
* @param a ean13 barcode numeric value
* @return the escpos code for the barcode print
* Description uses escpos code, return code needed to print a ean13 barcode
*}
function TPrintEscPosToPort.getBarcodeEscPosCode(l_ean13:String):String;
var
l_return:String;
begin
l_return := CHR(29) + 'k' + CHR(67) + CHR(12);
l_return := l_return + l_ean13; // Print bar code
l_return := l_return + l_ean13; // Print bar code number under thge barcode
Result := l_return
end;
要打印到打印机
{**
* @param Printer Name, Item be printed, Cut the papers after the cut, #no of copies to print
* @return boolen, true if it printed
* Description prints a test page to the tysso printer
*}
function TPrintEscPosToPort.escPosPrint(const l_printer, l_textToPrint :String;l_cutPaper:Boolean=true;l_copies:integer=1): Boolean;
var
l_pPort,l_pName,l_tmp:String;
i,x:integer;
PrinterFile: TextFile;
begin
// set result to false so any thing other then a good print will be false
Result:= FALSE;
try
//Find if the printer exists, else set to defult -1
i := Printer.Printers.IndexOf(l_printer);
if (i > -1) then
begin
Printer.PrinterIndex := i;
l_pName := Printer.Printers[i]; //Get the printer name (incase its the defult and not the one passed)
l_pPort := Self.getPrinterPort(l_pName) ; // get the port name from the reg
end;
// If true add headers and footers to the passed text
if (Self.aPrintHeadersFooters) then
begin
l_tmp := Self.getHeader()
+ l_textToPrint + Self.GetFooter();
end
else
begin
l_tmp := l_textToPrint;
end;
//Send the Document To the printer
try
for x:= 1 to l_copies do //Print multi-copies
Begin
//Assign the file to a tmp file in the printer port
if (length(trim(l_pPort)) > 0) then AssignFile(PrinterFile,l_pPort)
else
begin
//only use if we cant get the port
//(may look bad as ctrl codes are still in place)
AssignPrn(PrinterFile);
l_tmp := Self.stripEscPos(l_tmp);
end;
Rewrite(PrinterFile);
try
//Send the passed Text to the printer
WriteLn(PrinterFile,l_tmp);
if (Self.aPrinterReset) then
WriteLn(PrinterFile,escReset); // Reset the printer alignment
if (l_cutPaper) then
WriteLn(PrinterFile,escFeedAndCut); //Cut the paper if needed
finally
CloseFile(PrinterFile);
Result:= true;
end;
end;
except
end;
except
end;
end;

下面是一个丢失的从上述代码的控制代码常量,希望的名称是足够的描述。
const
escNewLine = chr(10); // New line (LF line feed)
escUnerlineOn = chr(27) + chr(45) + chr(1); // Unerline On
escUnerlineOnx2 = chr(27) + chr(45) + chr(2); // Unerline On x 2
escUnerlineOff = chr(27) + chr(45) + chr(0); // Unerline Off
escBoldOn = chr(27) + chr(69) + chr(1); // Bold On
escBoldOff = chr(27) + chr(69) + chr(0); // Bold Off
escNegativeOn = chr(29) + chr(66) + chr(1); // White On Black On'
escNegativeOff = chr(29) + chr(66) + chr(0); // White On Black Off
esc8CpiOn = chr(29) + chr(33) + chr(16); // Font Size x2 On
esc8CpiOff = chr(29) + chr(33) + chr(0); // Font Size x2 Off
esc16Cpi = chr(27) + chr(77) + chr(48); // Font A - Normal Font
esc20Cpi = chr(27) + chr(77) + chr(49); // Font B - Small Font
escReset = chr(27) + chr(64); //chr(27) + chr(77) + chr(48); // Reset Printer
escFeedAndCut = chr(29) + chr(86) + chr(65); // Partial Cut and feed
escAlignLeft = chr(27) + chr(97) + chr(48); // Align Text to the Left
escAlignCenter = chr(27) + chr(97) + chr(49); // Align Text to the Center
escAlignRight = chr(27) + chr(97) + chr(50); // Align Text to the Right
其他提示
获取微软POS对于.NET 1.11,它有,包括执行的POS硬件所有的基本操作的示例应用程序的SDK。我用它所有的时间来测试钱箱工作确定为例子。
还有包括(在.net)源代码,所以你可以看到他们是如何做到这一点。
