Problem with printing-quality

Using the vi-preference "printing frontpanel after finish" never makes a
printout that look simular to the frontpanel on the screen. So I use the
print-panel-VI, but there are i.e. grids in graphs missing and the
textletters have a bad resolution (every letter is build by little
quares).

Anybody knows a solution to make good-quality printouts?

thanx Niko

Hi Nikolai,

if you want's to do it by yourself, just take a capture program with
window capture function. Then you can print the frontpanel with a
standard graphic program.

It will work this way, but I thought, it should work programaticly out of
LabVIEW.
Any other ideas??

Have you tried the various print options? With LabVIEW 6, its under Tools>Options. With LabVIEW 5, its under Edit>Preferences. What I have found is that sometimes the problem is the printer/driver itself. Trying to reproduce all the details of a screen at 1280x1024 pixels may be very difficult with a 300 dpi printer.

You can try the following:

wire the VI reference to a invoke node and select "Get Image Panel".
Save the picture to your harddisk. Generate a report using report
generation VIs and Function. You need LV on Windows to use the report
utilities.

Hope that helps

Hi Nikolai!

One time we solved a similar problem in a quick and easy way:
We made a huge graph indicator - 4 times bigger than screen size - in the
front panel
and set "scale (printed panel) to fit (page)" in LV5 VI setup (or LV6 VI
properties).
The printout had a much better resolution.
Disadvantage: It takes a lot of time and memory.

You might consider converting your plot data to HPGL, and printing it
directly to your inkjet or laser printer using a shareware program called
"PrintGL." The results are beautiful. You can add labels and fonts and
all kinds of stuff.

PrintGL (actually PrintGLN.exe) is available from Ravitz Software.
Cost is about $80. Check it out at:
http://www.concentric.net/~ravitz/
From LabView, you would call PrintGL using the EXEC.vi

The Preferences or Options dialog allow for you to choose between several
built-in printing techniques, each with its own tradeoffs. The simplest,
that looks the most like the screen is bitmap printing. It will work very
similar to a screen capture, complete with blocky characters, just like the
screen.

The nicest output often comes from the postscript printing. In this mode,
LV bypasses the different printin
g and display drivers and generates raw
postscript and sends it to the printer. This currently cannot download
fonts to the printer, so some substitutions may be made. This is most
noticible with symbol and wingding types of fonts.

The default, standard type of printing draws the same drawing commands to
the printer as to the display window. Because the resolution of the devices
is different, things like line widths have different results.

Print front panel on completion can use any of these printing options. Be
sure to restart LV after changing the printing options in order for them to
take effect.
