あなたのために働くかもしれません-これは、アクティブなプリンターを変更せずに印刷するためにWordで実行しなければならなかったことです。エラーが発生し、Wordがプリンター名だけを気に入ったり、ポートも必要とする場合があることがわかりました。
... プリンター名とポートを取得するには、以下のように InstalledPrinter を使用します
private InstalledPrinter PreferredPrinter { get; set; }
private InstalledPrinter DefaultPrinter { get; set; }
private void SetDefaultAndPreferredPrinters()
{
if (UserSettings[SETTING_PREFERRED_PRINTER] == null)
{
UserSettings[SETTING_PREFERRED_PRINTER] = string.Empty;
}
_preferredPrinterName = ((string)UserSettings[SETTING_PREFERRED_PRINTER]).Trim();
List<InstalledPrinter> installedPrinters = InstalledPrinter.GetList();
DefaultPrinter = null;
PreferredPrinter = null;
foreach (InstalledPrinter installedPrinter in installedPrinters)
{
if (installedPrinter.IsDefault)
{
DefaultPrinter = installedPrinter;
}
if (installedPrinter.Name.Equals(_preferredPrinterName, StringComparison.InvariantCultureIgnoreCase))
{
PreferredPrinter = installedPrinter;
}
}
}
public enum PrinterStatus{
Other = 1,
Unknown,
Idle,
Printing,
Warmup,
Stopped,
Offline,
Degraded
}
public class InstalledPrinter{
private static readonly ILog _s_logger =
LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
public string DriverName { get; set; }
public string Location { get; set; }
public string Name { get; set; }
public bool Network { get; set; }
public string PortName { get; set; }
public string ServerName { get; set; }
public bool Shared { get; set; }
public PrinterStatus Status { get; set; }
public bool WorkOffline { get; set; }
public bool IsDefault { get; set; }
public static List<InstalledPrinter> GetList()
{
PrinterSettings ps = new PrinterSettings();
string sDefault = ps.PrinterName;
string query = "Select * From Win32_Printer";
ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);
ManagementObjectCollection results = searcher.Get();
List<InstalledPrinter> list = new List<InstalledPrinter>(results.Count);
foreach (ManagementObject printManagementObject in results)
{
InstalledPrinter entry = new InstalledPrinter();
foreach (PropertyInfo propertyInfo in typeof(InstalledPrinter).GetProperties()) {
object[] oparams = {1};
if (propertyInfo.Name != "IsDefault") {//The IsDefault property is worked out logically, the rest of the properties map identically to the columns of the WMI query results.
try {
oparams[0] = ConvertValue(
printManagementObject[propertyInfo.Name], propertyInfo.PropertyType);
propertyInfo.GetSetMethod().Invoke(
entry,
oparams);
}catch(Exception e) {
_s_logger.Error(string.Format("Failed to enumerate printer property Name:{0}, Type:{1}", propertyInfo.Name, propertyInfo.PropertyType));
}
}
}
_s_logger.Info(string.Format("Finished enumerating properties of printer: {0}", entry.Name == null ? "<Null>" : entry.Name));
if (sDefault.Equals(entry.Name, StringComparison.CurrentCultureIgnoreCase)) {
entry.IsDefault = true;
}
list.Add(entry);
}
return list;
}
private static object ConvertValue(object value, Type type)
{
if (value != null)
{
object printerStatusRetval = null;
if (type == typeof(DateTime))
{
string time = value.ToString();
time = time.Substring(0, time.IndexOf("."));
return DateTime.ParseExact(time, "yyyyMMddHHmmss", null);
}
else if (type == typeof(long))
return Convert.ToInt64(value);
else if (type == typeof(int))
return Convert.ToInt32(value);
else if (type == typeof(short))
return Convert.ToInt16(value);
else if (type == typeof(string))
return value.ToString();
else if (type == typeof(PrinterStatus))
try {
printerStatusRetval = Enum.Parse(typeof (PrinterStatus), value.ToString());
} catch (Exception e) {
_s_logger.Error(string.Format("Failed to convert PrinterStatus with value {0}", value));
printerStatusRetval = value.ToString();
}
return printerStatusRetval;
}
return null;
}
}
...次に、Word をインスタンス化した後、プリンターを設定するために次のようなものがあります。
object[] oWordDialogParams = {PreferredPrinter.Name, true};
object[] oWordDialogParamsWithPort = {string.Format("{0} on {1}", PreferredPrinter.Name, PreferredPrinter.PortName), true};
string[] argNames = {"Printer", "DoNotSetAsSysDefault"};
//oWord is my own class that provides a fairly simple wrapper around MS Word
oWord.Application.ActivePrinter = UserSettings[SETTING_PREFERRED_PRINTER] as string;
Dialog printDialog = oWord.Application.Dialogs[WdWordDialog.wdDialogFilePrintSetup];
object wordBasic = oWord.Application.WordBasic;
try {
wordBasic.GetType().InvokeMember("FilePrintSetup"
, BindingFlags.InvokeMethod
, null
, wordBasic
, oWordDialogParams
, null
, null
, argNames);
}catch(Exception e) {
_s_logger.Info("Failed to print using printer name, trying printer name and port", e);
try {
wordBasic.GetType().InvokeMember("FilePrintSetup"
, BindingFlags.InvokeMethod
, null
, wordBasic
, oWordDialogParamsWithPort
, null
, null
, argNames);
}catch(Exception e2) {
_s_logger.Info("Failed to print using printer name and port", e2);
throw;
}
}
