How can I detect "print completed"?

[vix]

Hi all,

I want to do an operation like this:

1. read data from file_01.txt

2. put these data in a XYgraph

3. print the XYgraph image

4. load the next data file

5. back to point 2

I used the "Print Panel To Printer Method" in a for loop, but the second file is loaded before the first print is completed, and so on

Can I read the print status? (so I could wait until print is completed before loading the next file)

Any suggestion?

Thanks a lot in advance.

Hi,

Im not sure, but I guess if you disable the spool function of your printer (in XP: advanced printer properties/ print directly to printer) Labview will wait until the print job is done.

Kind regards,

The problem is that I can't modify that option because I'm connected to a shared printer, and I haven't the administrator rigths.

Could you post some code or a picture of it?

I just made a simple example which seems to work properly.

You're rigth, but the problem is that the Front Panel is updated quickly, so in the graph I only can see the last data set (even if the documents in print queue are correct - i.e. all different -).

I'd like to see the first data set, so I can type the correct name for the pdf file i want to obtain, then see the second data set and type the proper pdf file, and so on ...

Probably I made some confusion before, but I need to print both on an a physical printer (which is a shared one) and a virtual printer (PDFCreator) to obtain a pdf file.

I made experiements using Standard Report, but the image quality in the pdf was really poor.

But you have the possibility to control the sequence using the dataflow and you can use a sequence structure in addition to that. So as you want, can have each operation in a separate frame of the sequence structure. I did it this way too in the example.
