Rif.: Replacement for NIReport_GetPrinters ?

[Bertrand_ENAC]

Hi,

In CVI 2017 projects, I used NI_Report_GetPrinters.

Since CVI 2019 NI report has been removed.

How can I now get the available printers?

Thank you

One possibility is to get them via VMI; you have to query Win32_printer object and list all instances.

You can take my example on getting system info via VMI as a starting point to elaborate on.

Hi Roberto,

Thank you for sharing your example.

It seems a bit complicated to me, but I will try to understand in order to get the connected printers.

Do you know why NI has removed NIReport from the CVI package?

Bertrand, I know that I am the developer of that sample program and so it's easier for me to modify it, but it took only a few minutes for me to extend the app adding the list of printers taking one of the available querying function and modifying it for win32_printers: I'm confident you will succeed as well considering that I structured all queries in 3 steps: preparation of the environment, actual querying step and closing step. You'll have to operate only on the second one.

As per NI_Reports, I don't know why but that instrument was declared closed by Luis G back in 2011 when he declined my suggestion to add a preview facility to it. Given that, it was only a matter of time for NIReport to be removed from CVI distributions.

Having said this, you should take a look at the last post by macksel in this other idea, which seems to suggest there is still a way to have NIReport working.

Disclaimer: I am not interested in using NIReport so I did not tried what macksel suggests.

The underlaying NI Report ActiveX control was old code they did not want to maintain and upgrade anymore. It would have required also work to make it 64-bit capable. So they decided to scrap it and not just in LabWindows/CVI. LabVIEW also had a provider in its Report palette that was using the NI Report engine. They kept the HTML and the Excel provider but removed the NI Report one.
