Privileges - .net 1.1 TCPIP Printer Port Creation With CreateProcessWithLogon API?
May 22, 2009A few months back I wrote a VB.net console application to migrate a group of about 100+ printers and the 1800+ users that use them from some old HP print appliances to a mixed Print Server and Direct to IP Printing solutions. The application uses a database to compare installed printers and remove old/invalid shares and remap to the new Win2K3 based print server OR create a TCPIP printer port and install the driver for direct to IP printing.
It worked really well, but users needed power user rights to create the TCPIP printer port. For the main campus this wasn't an issue, but the smaller remote sites need a solution that allows the app to be run by users without power user rights.
My solution was to take the "CreatePrinterIPPort" function and put it into it's own wrapper app and then call it as needed from the main app using a hard coded local admin account for the purpose, but I'm running into issues when spawning the createport app. If I run the app standalone it creates the port with no issue, but when I run it in my test app to spawn the createport using the CreateProcessWithLogon API the port creation fails with an "access denied" error. I'm limited to using .net 1.1 as 2.0 isn't in our environment throughly and I was told it wouldn't be pushed just for this app.

Printer Stuff - Detect If My Printer Is Busy ?
Mar 18, 20111. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating
