I have searched all over and can not find the printqueue anywhere. I'm using VS 2008 Pro, and .NET 3.5. I'm writting in Visual Basic.I create my document then send it to a previous selected printer. I do not give the user a printdialog I handle all the settings in the code. My problem is when the printer is not online, it triggers an unhandled exception. I would like to check the status of the printer just before the printdoc is sent, so that I can handle what to do when the printer is offline.
The main issue here, whether the ZPL printer is on/off, the status always shows as "Ready", there is no change in the status.made use off couple codes which i googled, but none have turned out to show me the printer status.
Is there any other way to indentify the status of the ZPL printer/ any other alternative [url]...

im making an application and i need to install a printer in a computer. The application im trying to do is a client-server application so the idea is that the server send the instruction to the client telling him what to do and then the client will do it, in this case it will go to a SAMBA directory and it will get the drivers for the printer model from there and after that it will install the printer, everything in silent mode.
Ive searched the forum and found numerous ways to print to pdf using itextsharp or a local pdf printer which is great. The problem I have is that "from what I can see" paths are specified to documents which are trying to be converted.Can anyone tell me if its possible for the VB code to point to say a pdf printer but not specify the document I wish to send. The reason for this (and if you've seen a simular post in the VB6 forum sorry - I decided to try .net). Im trying to incorporate the process to create an API.

I have an automated program that batch prints PDF files to certain network printers. On occasion our print server will go down & screw up the automated printing process & lose prints. I am looking for a way to check the status of the print server before sending prints. If the status is not "OK" then I want to pause the automated process until the server is back to "normal". Can anyone tell me how I would check this status or where I should be looking?
I see many web forms for doing a yahoo status check, I'm wondering if the same would be possible with a windows form? Basically have a form with a text box to enter the yahoo id, a button to submit and a message box reporting the status (online, offline, invisible).
My next step is to allow a pause checking the status of the motor and or inputs before going to the next step. Reason is so it does not do many calls to the motor controller so fast. I need some help building a loop that checks status of the motor and if Motor1Active is 1 which means it is running that it needs to wait a bit and then rechecks itself. If it is not running it will continue to the next step command. Here is a sample of what I got but need to figure out say a 50ms wait before rechecking. I guess a loop that rechecks and waits 50ms and then rechecks the status and if done and reads 0 then it goes to the next step. if still 1 output data it waits 50ms and then rechecks. The following is what I got started with but need help with if then else and anything else statement.
' get the current status of both motors and the digital inputs Private Sub GetMotorStatus_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles GetMotorStatus.Click Dim Motor1Active, Motor2Active, Motor1StepsLeft, Motor2StepsLeft, DigitalInputs As Integer
I have a form which I use to read data from a text file and export it to an excel template file. The data it reads is constantly updated so I would like to add a check box to cause the data to be read every 10 seconds. It's set up so the user can either do one quick scan by clicking a button, or they can click the button while also having the check box checked and it will scan every 10 seconds.The problem is, once I check the check box, I can't uncheck it. I have created a greatly simplified version of my original code to demonstrate this concept.
