How to get a list of avaiable network printers.

[chandansify]

Hi All,

Can anyone help me out to get the list of avaiable network printers in current domain.


It is like getting a list of available printer via...
Start ---> Search ----> Find Printers---->entire Directory


Can anyone suggest any api to populate list of all network printers available.


Thanks and regards,
Chandan Banga

[chandansify]

thanks for guiding me. This is really helpful to get and set the printer on a particular system.

But...........


What I am looking is....getting a list of all network printers available in my domain network.

not only the installed printers but all others available in network.

There is extensive help here http://word.mvps.org/FAQs/MacrosVBA/...lePrinters.htm but this is for MS Word so look at the rest of the article here http://pubs.logicalexpressions.com/p...cle.asp?ID=183 which explains how to use it!

Regards,
Simon

Here is some code that lists them in a listbox on a userform
