can't print block diagram.

[LoKey]

I have inherited a rather large and messy VI.
I cannot print the block diagram.
Just get header info and blank page.
Running LabVIEW 7 on standard PC with standard printer in standard
mode...do not have trouble with other VIs.
I can print the front panel, etc. for the VI in question, just can't
print the block diagram.
Can't print to printer, PDF, HTML, nothing. Just get header info and
blank pages.
any hints?
thanks

Not sure what is causing that paticular diagram to not print (unless there is possible driver issue with the printer). One way to work around it (if using Windows) may be to bring up the diagram in question, hit Alt+Print Screen, then do a paste with Ctrl+V into a paint program then try to print from the paint program.

Hello Paul,

What operating system are you using? The 'older' Windows OS's (95/98/ME) do not support very large bitmaps. This would make it so that the LabVIEW block diagram would print fine for smaller diagrams, but once it passes the maximum size of the OS, it does not print. The "breaking point" for the bitmap size differs considerably among various PCs, but it could be as low as about 2000x2000 pixels, and probably not more than about 4000x4000.

Unfortunately, if this is the behavior you are seeing, it is a limitation of the OS, so the only workaround would be to copy and paste the image through some sort of graphics editor, or pare down the size of the block diagram by converting some pieces of code to subVIs and compressing (which is what I would recommen
d).

Hope this helps!
