Difference between revisions of "Internet Printing Protocol"

Microsoft has implemented IPP since Windows 2000, and the webpage hasn't changed much over the years.
I find it annoying that the default page doesn't sort the printers. So I've put together a way to sort them based on "Location"

Editing ASP pages

To do this you will need to make changes to the IPP ASP files.
You can find them here:

%windir%\web\printers\

arraySort Function

Save the code below to:

 %windir%\web\printers\my.inc

ipp_0001.asp

Now that you have created the custom include file we need to reference it.
Edit the following file:

  %windir%\web\printers\ipp_0001.asp

Find this line (typically line# 14): and insert this line below it

Now find this line (typically line# 123):

rgADSIGetPrinters = rgPrinters

Comment it out so it looks like this:

' rgADSIGetPrinters = rgPrinters

Insert this new line:

rgADSIGetPrinters = arraySort(rgPrinters,2,"a")

Save and exit
