Printing

[vicmart]

Hi,

I am trying to print signals off my VI graph, all I get is a blank graph without any signal and even the scale on the blank graph does not match what is on my VI.

Hi Vic,

can you show what you have so far? How do you try to print it? You can use an invoke node to get a picture of your graph and print it than.

Show us your code or at least the portion of the code which both refreshes / displays the image and where it prints.

You may have a race condition..  The printer is faster than the eye 😉  (At the least the print buffer).  If the print command is reached before the image was processed, you'd end up with a blank picture.

Hi there,

I am very new to labview, please help on the attached file. All I want is to be able to print the signals without the black background unto A4 paper.

Hi Mike,

Please find attached what I have done so far. I want to be able to print the signals on paper without the black background.

Hi Vic,

you can convert your data to dynamic or you can create a picture. See both abilities in the attached example.

Hope it helps.

There seems to be an error. The VI prompts me for some files e.g append VI

When? While loading, or while running? I use the same vi´s as you.

Hi Vic,

try this please. It is without the create picture solution. It uses only the vi´s which you use.
Hope this helps.
