How to print picture

[田淇予]

I used a program to generate a picture. I want to print it directly with a printer instead of inserting word or ecxcel. What should I do?

[LVNinja]

Go to windows explorer, right click on the file and select "Print".

If you attached your LabVIEW code, we'd be able to tell what you did to generate the picture.  We'd then (probably) be able to advise you how to export your "picture" (or "image") to as suitable format (like .bmp, .png, .jpeg, etc.) that could be sent to a printer by asking Windows to send the file to the Printer of your choice.

If you are using LabVIEW 2023, please "Save for Previous Version" and specify LabVIEW 2021 or 2019 to get more of the "old-timers" to venture an opinion.

Place your picture on the front panel, then invoke node Print.Panel To Printer:

This is probably one of the easiest ways.

You can use a function called Read JPEG file then use draw functions to show on the picture indicator, then use the property node described before to print front panel after execution. 

Go to VI Properties -> Print 

Select the last item.

This is a very generic questions and, (unless you posted in the wrong place!!!), maybe you are actually talking about a LabVIEW program where the picture is displayed on the LabVIEW front panel and you want to use LabVIEW to print this directly.

Assuming this is a LabVIEW question, we can give more specific help once you show us what you have. There are plenty of ways!

Use "System Exec.vi":

mspaint.exe -p imagePath

Thank you for your reply, butI want to trigger the printer by clicking a button when the software generates pictures.

[LVNinja]

please properly describe what you are trying to accomplish.

Again, show us what you have? Do you have a suitable defined default printer?
