Front panel doesn't print

I am trying to print my VI. I can see the front panel in Print Preview. When it prints the front panel page is blank. Anybody else run into this problem and how did you fix it.
Thanks
Chris Gallo

Are you using any decorations on the front panel? Perhaps drawing a border around the panel?
(Reason I ask is that I once had a border decoration print over the controls it was supposed to be behind. I'm not sure what happened, since I could access the controls while running the VI, but for some reason, when I went to print, it thought it was in front of the controls. After selecting the border and sending it to the back again, it fixed the problem.)

HAVE SOUND- FRONT PANEL DOESN'T WO

hmmm, okay. Last night I installed the "Beta" driver and the EAX driver. I now have sound but my front panel doesn;t work. For some reason XP doesn't see the panels devices properly and lists all of them on the panel board as UNKNOWN devices. Is there some other driver set I need to install the front panel?

Hello tonitpp:
Unfortunately, the "Run VI" method only executes the vi and it will not open the front panel.
If you want to open the front panel, use the "Open FP" method, which is also located on the same class.
I hope this helps.

LV8.0 Auto-print front panel doesn't work

On the front panel in VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' is cleared when you exit the VI Properties dialog and return to it. Consequently, you can't get the front panel to print by checking this option.

Bshu,
You're absolutely right. That functionality is faulty. A work around may be to use the operate>>print at completion function. FYI: if you enable this property, the VI Properties/Print Options the 'Automatically print front panel every time VI completes execution' turns black. R&D is aware of both of these problems. Thank you for you're very valuable feedback and post to let us know if there's anything else we can help out with.

Printed front panel graphics quality (Print Panel to Printer method vs. Append Front Panel Image to Report.vi)

LV 6.02 (or 6.1)
NT 4.0
I have a vi that the front panel includes all the information I need to print except that it is on different pages of a tab control to conserve screen space. I was attempting to programatically cycle the value of the tab control in a For loop and invoke the Print Panel to Printer method to print 7 pages of the front panel, each with a different tab page selected. The printouts were excellent quality but beginning with the second consecutive Print Panel to Printer method the on screen front panel image of the VI being printed would become jumbled (sometimes, by the time 7 printings were done, the entire front panel image would disappe
ar and a bitmap of the desktop or underlying windows would be visible in the VI's panel frame) yet the subsequent Print Panel to Printer methods continued to print the panel as they should appear. The visible front panel graphics would never return to normal and the only solution was to close the vi (in the dev system) or exe (compiled) and re-launch. I tried a lot of things (like hiding the panel to print before printing and showing it after printing) with no luck. It appears that two or more of these consecutive invoke methods caused the problem regardless of whether the tabs were cycling, or even if there was no tab control and much fewer controls on the panel to be printed than normal. I also had the same problem with LV 6.1.
Finally, I was forced to switch to the report generation toolkit vi's, I cycle through the tab pages and use the Append Front Panel Image to Report.vi to append each image to the report. This is faster and control returns to my program quicker but I a
m unhappy with the printed quality of the graphics of the front panels. They are not as high of resolution as those generated via the Print Panel to Printer method.
Any suggestions?

You might try changing the way the VI is printed by going to tools >> options >> printing. Try the postscript and bitmap settings.

Running executable as a service, the front panel doesn't display properly upon the second logon.

I am running a LabView executable as a service. When I logon the first time, I see the front panel correctly. When I logoff, the service still runs properly. If I logon a second time, the frontpanel never fills in. (I see the desktop through the front panel). The service still runs, but when I click on any menu, the computer freezes. Any suggestions? (Other than not logging on twice)

Hi chach,
I hate to say it, but I'm surprised it even runs once. If you check out:
this link
It says the following:
"The service must run without a user interface."
As the article mentions, you could still have a separate front panel that communicates with the service, but the service itself probably doesn't have an accessible front panel.

My front panel doesn't show

Hi,
I have a vi (1) that calls a subvi (2) when I press a button. This subvi (2) calls the vi (1) again when I press another button. I have a event structure for this button (button of the subvi (2) ) where I set to false FP Open property for the vi (1) and then I call by reference this vi (1) and I do an invoke node (run) to show the front panel of it but it doesn't work. Why?
I post an image.
Thanks,
ToNi

Hi ToNi
I attach you another 2 simple solutions. One with the FP.State property and the other using the close function of the vi reference.
The problem using the close function is, that the first vi doesn't open in running mode. Using the function "Open FP" the vi opens, but I can't run it.
This problem is avoidable using the FP.State property.
To run the vi's, vi1.vi and vi2.vi of the close directory must be copied to c: or you have to change the absolute paths in the vi's.
I hope this is what you are looking for and it helps.

Problem about asynchronous call: subVI front panel doesn't pop up when called.

Dear All,
I'm new to LabVIEW, and this is the first time I try to use the asynchronous call.
I'm using LabVIEW 2011.
I want to build a directory for several VIs, and it should allow users to open more than one of the VIs at the same time by pushing the buttons. Before building this directory, I simply tried to use asynchronous call to call a VI form another VI, but found a big problem.
I followed the steps in the help file, created a strictly typed reference, set the option to x80 because I don't need the return. When I run it for the first time, it worked fine: the subVI popped up and run. Then I closed the subVI. But for the sencond time and on, when I run the caller VI, the subVI didn't pop up, instead it seemed to run silently on background because when I manually opened it from the file I found it running. Besides, I didn't find any option like "show front panel when called" of the asynchronous call.
The caller VI and subVI are attached. The address of subVI in caller VI should be changed accordingly.
What should I do to make it work properly? Thanks very much for any idea!
Solved!

Jeff, you will be happy to know that I used this tactic in full force on a project recently (lots of dialogs in this program). Not sure how many LabVIEW reboots it has saved me from. Reuse VIs made it even easier to do.

Front panel not aligning properly on scale print

So I've created a custom print VI with various graphics that I'd like to print on an 11x17 sheet of paper in landscape mode, but for the life of me I can't get the thing to align properly. I want the front panel to print centered with 0.1 - 0.2 inch margins all around, but instead of doing this, the front panel will sometimes print aligned to the left and top or other times to the right and top (with wrong margins always on two sides, sometimes three or four). I'm using a programmatic call to the easy print function that scales the front panel to fit on this size. However, even after making the proportions of objects on the VI 11:17 (vertical: horizontal) I still can't seem to get this thing to center properly. Any ideas of what the problem could be?

Ok, So I created a blank VI with a 1280 x 1978 frame decoration, yet the print preview in labview still doesn't seem to show the thing with proper alignment.
Looking at the picture, looks like it's aligned along the right and top of the page rather than uniformly centered. Ideally, the frame would uniformly cover all the edges around the page in the preview. I suspect this is an issue with LabVIEW and not my printer, as I can set my printer to borderless printing.
Any ideas?

Printing front panel of VI - no borders appear around the indicator box values

Dear readers,
I am using Labview 6.1 on a pentium PC with adequate memory etc. I've been trying to print out the front panel of my VI using a postscript printer and the post script printing options available in the Labview. I notice that the printed front panel doesn't show the rectangular borders that is supposed to surround the values contained in indicators and controls.
Apart from this problem, everything looks good, such as it prints out in the way that I want...with nice white background to not waste ink.
Could someone please advise me on what options to set up in order to print the borders around the indicator box values? Thanks very much for any help.
I noticed that for
an older Labview for the apple Mac, namely Labview 4 for the Mac, you can just print the window of the front panel and everything comes out wonderful....you get the borders around the indicator and control box values.
Thanks again.
Kenny Leong

Hi Mike!
Thanks for replying to my post. Greatly appreciated. Is it possible to set the colours for the indicator edges? I'll attach a screen capture of my front panel, and also a digi-pic of the print out. The printout is ok except there's no borders around the indicator values. I printed it out on a hp laserjet 6MP printer as well as on a hp 4050 printer and the printed panels have no borders around the values. I'll attach my front panel vi too. Thanks a lot Mike.

HP 6500 wireless ALL-in-one e709n Printer front panel not responding at all

Hi there,
I have got a HP 6500 wireless ALL-in-one e709n printer.
I have been using it with my pc with windows vista on it for nearly 2 years and it has been great.
1 month ago, the front panel of the printer stopped responding, ie, when i press any buttons, the lcd screen on the printer does not change, it always show the ink level.
The printer turns on, shows that its preparing, then goes to idle state with ink level icons on the screen.
If i try to print any documents, it works with ethernet cable connected to my pc (which i used to do it wirelessly) , the cable-connected printing function still works, but wireless printing does not work anymore.
However if i try to scan something, on the pc when i open the hp scan app, it shows that 'scanner is not available'.
Also because the front panel doesnt work, no buttons respond, i cannot scan or copy.
I have tried unplug everything and reinstall all drivers and programs.
No damage to printer or my pc, it just stopped working all the sudden.
Can any one help me out please?
cheers,
Charlie

Save front panels and print them at once

I have a VI that will be executed multiple times with different data, i want each of this front panels to be printed but it has to be one print instruction. I've tried to make an image of the front panel and append this to an Report, but the image is of a bad quality and the image which was made, contained only the view on screen!

If you want a report that is an image of the display screen one thing you can do is create a VI whose front panel is a clone of the application's front panel. The only code behind this front panels would be property nodes to set the clone's front panel to match changes the user makes in the display during execution (for example, a user can change the color of plots, or the such things). It is vital that the diagram of this VI has at least 1 property node, otherwise it will only update if its window is open.
Now as you main application is running it gathers a collection of all the data that you will want to print. When the user then clicks a print button, or the program exits (however you want the program to work) the code would take each dataset and one at a
time pass it to the clone VI and programatically print its front panel.
However, if all you have is tabular data (i.e. no plots or other graphics) I have found it easier to use the report generator VIs, but it's your call.

Can't print front panel graphics

I am unable to print any front panel graphics with either the file>>print function or the print at completion selection. If only text is on the front panel it will print, but any graphics will make the printer say that it is spooling for about 5 min and then say it is printing, but it won't. If I first print to HTML and then print from the webbrowser the printer works fine. Are there any reasons for this and any solutions?

What version of LabVIEW are you using?
What are your LabVIEW print preferences (Standard, postscript, bitmap, color, etc.) and what kind of printer are you using?

Open VI's front panel

Hi,
See the included file 'Printing.bmp'.
I am printing a VI's front panel, but before printing I want to open another VI's front panel that is showing the message 'Printing...'(P'ting). This VI's front panel should be closed after printing. But the front panel of P'ting.vi could not be drawn completely within the printing time. I just can see the borders of the VI. How can I solve this?
greetings
Davy

Sorry I did not see the picture...
I don't know what your CPU is like, but the time LV needs to send the printing commands is very small.
When using a pause, use a sequence to be sure that the pause starts before the printing.

HP OFFICEJET 6500 709A WILL NOT SCAN FROM FRONT PANEL ON MACHINE os windows 7 what must be done?

I have an oj 6500 709a all in one that will not scan when I press the scan button on machine.I have doown loaded all the updates and drivers.what must be done ?

Hi z5090joe,
Thanks for the response!
We can check a few other things, since the scan communication itself seems to be working okay, just not from the front of the printer. I'd like to check the Scan Settings on the front panel with in the HP Solution Center.
Once you're in the HP Solution Center, please click on Settings along the bottom, click Scan Settings, then click Scan To... Setup.
You will then see a screen that has Available Scan Shortcuts on the left and Front Panel List (Scan To button) on the right. If there are no options on the right, please add the scan options you'd like from the left side by clicking on it and then clicking the Add button in the middle. If you add one by mistake just click on it and then click Remove. Once you've added the options click Update the Device and then OK on the next screen.
If there are options on the right side when you open it, please Remove all of the options, click Update the Device, and then go back to the Settings screen, before following the same process described above to add the options to the right side.
Once you've added the options check the front panel of the printer. If they still aren't there, please turn the printer off for 30 seconds before turning it back on (use the power button not the power cord) and try the Scan option again.
Let me know how this goes for you!
