Access Your Network Printer RRS feed

  • User-1163549985 posted
    I managed to put together several pieces of code from the web to allow network printing. Most of the examples I found were written in C#. This script can be useful for placing orders with warehouses etc that allow access to their network printers.. etc. <%@ outputcache location="None" %> <%@ Page Language="VB" Debug="True"%> <%@ Import Namespace="System" %> <%@ Import Namespace="System.Collections" %> <%@ Import Namespace="System.Collections.Specialized" %> <%@ Import Namespace="System.ComponentModel" %> <%@ Import Namespace="System.IO" %> <%@ Import Namespace="System.Drawing" %> <%@ Import Namespace="System.Drawing.Printing " %> <%@ Import Namespace="System.Text" %> <%@ Import Namespace="System.Web" %> <script language="VB" runat="server"> Sub Submit_Click(ByVal sender As Object, ByVal e As EventArgs) Try Dim pd as New PrintDocument() ' Set the printer name. pd.PrinterSettings.PrinterName = "\\NS5\hpoffice" AddHandler pd.PrintPage, AddressOf Me.pd_PrintPage pd.Print() Catch ex as Exception Response.Write("Error: " & ex.ToString) End Try End Sub Private Sub pd_PrintPage(ByVal sender as Object, ByVal ev as PrintPageeventArgs) Dim yPos as Single = 250 Dim leftMargin as Single = ev.MarginBounds.Left Dim topMargin as Single = ev.MarginBounds.Top Dim printFont = New Font("Arial", 10) Dim sb As StringBuilder = New StringBuilder() ' Page title and date/time. sb.Append("Warehouse Shipment Request") sb.Append(Environment.NewLine) sb.Append("DateTime: " + DateTime.Now.ToString()+ Environment.NewLine) ' Iterate submitted form fields and get field names.

    Seems to work great on Intranet. Haven't had the opportunity to try it external. Let me know how it does if you do.

    I am trying to create a scenario where a .NET web form sends it's results to a network printer. I copied and pasted your code onto a .aspx page and changed the printer variable to point to a network printer here in my office. When I hit submit I get an error. Do I need to apply permissions or perhaps I am not inserting the correct network printer path.

    Hi there,

    I am having the same problems. Tried to access printer with Invalid Setting. And yes, I did set the printer path to the actuall path on my network. Could this be a security issue? I trying to print server side from an aspx page. When debugging on my development machine it works fine, but when I deploy it on the live server i get the error.

    Has anybody else encountered this problem?? Is there a solution for it?

    Thanks in advance

    I believe the problem with printing to a network printer is that the network printed doesn't exist unless there is a user logged into the server which the asp.net application is running.  Try creating a local printer that points directly to the network printer.  Local printers are accessable through code when a user is not logged in.

    Superlite - awesome code. This was something I've been looking for a while. It isn't exactly what I need, but the things that I was having a hard time figuring out you've done a fine job of getting me off to a good start with. Excellent addition to the developer community!

    I'm having the "settings to access printer "networkprinter" are invalid" problem as well.  Did anyone find a solution to this?  I couldn't figure out how to setup a local printer to point to a network printer.

    Thanks,

    Hello, we have another forum going which is dealing with similar issue:

    http://forums.asp.net/1517337/ShowThread.aspx#1517337

    this one seems to contain more specific ino however:

     I have been worjking on jthis for a little while now and have experimented with essentially two methods

    1. using printDocument class

    2. using MS sample RawPrinterHelper (taking over the winspool.Drv )

    I managed to get both methods working however they both fail when I try to get the printer to abide by the HTML formatting. The best I can do is get it to spit out the HTML tags as part of the ASCII stream.

    I'll be glad to share my code or provide help configuring the th network printers so that they are called correctlly (hint: you will have better success if you configure the Printer on it's own virtual port which requires that it's using a local driver on the application server)

    back to my issue: I have gone as far as saving my results as an HTML file on the server. Now all I am tring to do is tell the printer that it's HTML and that it should format it accordinglly and not print out the tags. Sounds fairly simple because we all know that you can print out HTML documents formatted properlly however both methods i've tried are actually parsing out text on the page as a stream and sends it to the printer as such without telling the printer that it's HTML.....

    Help....?

    I might be pointing out something really obvious here, but maybe the  printer name you are using is a relative reference, when on the web the printer is not  on the server's network, and the printer needs to be referenced directly (maybe by IP address)?

     

    Just a thought,

    As a potential supplement, i use the following function to get an array of printers on a server. You can bind this to a drop-down, etc and then the user can select from the available printers (on the server) to use.

     

    Imports System.Drawing.Printing

    Imports System.Collections.Generic 

     

    Public Shared Function ListPrinters(ByVal PrinterType As String) As String()

    Dim lst As New List(Of String)

    Dim PrintPermissions As New PrintingPermission(System.Security.Permissions.PermissionState.Unrestricted)

    PrintPermissions.Level = PrintingPermissionLevel.AllPrinting

    For Each printer As String In PrinterSettings.InstalledPrinters

    lst.Add(printer)

    Next

    lst.Sort()

    Return lst.ToArray

    End Function

    Did you ever get any solution to this? I am still searching for one as well. I tried a product called aspprinter. Formating under this product works great, but you cannot set the printer you wish to print the html code to. I tried using System.management namespace to set the default printer first, but the SetDefaultPrinter method won't work in asp.net only in windows forms.
