I am trying to write a program that allows me to print a ssrs report(.rdl file) from the server-side code to a predetermined printer without any pop ups asking me which printer I want to use can this be done?
EDIT
Also pasted the code for the ReportViewerDisposer implementation I'm using.
Together with the class ReportViewerDisposer found here I'm using the following code, which is part of a larger project, but you should be able to adapt it easily:
private string m_printerName;
private string m_server;
private string m_path;
private string m_name;
private Dictionary<string, string> m_parameters;
private SizeF m_pageSize;
private float m_marginLeft;
private float m_marginTop;
private float m_marginRight;
private float m_marginBottom;
private short m_copies;
private int m_currentPageIndex;
private List<Stream> m_reportStreams;
public void PrintReport()
{
string mime, extension;
ReportViewer viewer = new ReportViewer();
ReportViewerDisposer disposer = new ReportViewerDisposer(viewer);
try
{
viewer.ProcessingMode = ProcessingMode.Remote;
viewer.ServerReport.ReportServerUrl = new Uri(String.Format("http://{0}/ReportServer", m_server));
viewer.ServerReport.ReportPath = String.Format("/{0}/{1}", m_path, m_name);
List<ReportParameter> param = new List<ReportParameter>();
foreach (ReportParameterInfo paramInfo in viewer.ServerReport.GetParameters())
{
if (m_parameters.ContainsKey(paramInfo.Name.ToUpperInvariant()))
{
string value = m_parameters[paramInfo.Name.ToUpperInvariant()];
param.Add(new ReportParameter(paramInfo.Name, value));
}
}
viewer.ServerReport.SetParameters(param);
viewer.RefreshReport();
CultureInfo us = new CultureInfo("en-US");
string deviceInfo = String.Format(
"<DeviceInfo>" +
" <OutputFormat>EMF</OutputFormat>" +
" <PageWidth>{0}cm</PageWidth>" +
" <PageHeight>{1}cm</PageHeight>" +

" <MarginLeft>{3}cm</MarginLeft>" +
" <MarginRight>{4}cm</MarginRight>" +
" <MarginBottom>{5}cm</MarginBottom>" +
"</DeviceInfo>",
Math.Round(m_pageSize.Width, 2).ToString(us),
Math.Round(m_pageSize.Height, 2).ToString(us),
Math.Round(m_marginTop, 2).ToString(us),
Math.Round(m_marginLeft, 2).ToString(us),
Math.Round(m_marginRight, 2).ToString(us),

urlAccessParameters.Add("rs:PersistStreams", "True");
