This example shows two PowerShell scripts. The first one shows the possibilities for the write-progress CmdLet. The second PowerShell script is a proper example script, showing all printers. For demo purposes, some start-sleep CmdLet’s are added.


The first script has OutputSettings default 1023, all write info is shown immediately in the textbox and provided back to the result. The second example has the normal output written back to the result. But all other output is not shown.


Note that the ‘start-sleep’ is internally replaced by ‘start-wait’, which handles forms refresh better that the original ‘start-sleep’.

The example script is easy to read  for the average PowerShell user. So just take a look at the code. There is also enough information and examples on the internet for PowerScript.
