why my printer does not work?

[fenny]

Last week, our administrator changed the printer. I also changed the printer name in my Labview program to be the name of the new printer he installed . it did work at first. I've printed out two graphs with this new printer. But suddenly, it didn't work again. the error is 'invalid printer name'. What are the most possible reasons that a printer refuse to work in my LABVIEW program?

I found this Knowledge Base on NI's website which seems to be an issue similar to yours. It suggests using the full path for the printer instead of the alias name and that this can sometimes solve the issue that you are facing. I hope this helps you out.

I'm not exactly sure what this error means, but I have seen it occur with Report Generation applications. The issue was resolved just by recompiling the VIs. To do this, hold down Ctrl and Alt buttons and click the Run button. You won't see anything happen but you will have to save the VI again. Try this and see if it works for you.

Thanks JRA.

I did as you told, but it did not work yet.

The strange thing si that I did succeeded printing out several times before I chnaged the printer name and after. But suddenly, it refused to corperate.
