.Net form Linear control


The Barcode height on code128 linear (BarHeightCM) is not always displayed the same on different computers when using the .NET Linear Forms Control. What is the reason and how to solve it?

Code-->
LinearCode.BarHeightCM = "0.5";

On some print previews, it is displayed and printed as 0.7 cm on others only 0.5cm

Best Answer

The only property that affects the barcode's height is the property BarHeightCM. Your computer's regional settings should not affect the control--neither should any other fonts that are installed.

If it is a setting on your machine, unfortunately, I could not provide any assistance to correct the issue as it would not specifically be related to the control. I am also not able to reproduce the issue on several computers now running WinXP to Win 7 (printing on laser and thermal printers).

If you would like to send a PDF of the barcode to admin@idautomation.com, I could take a look at the barcode.

Instead of the Forms Control, you may want to try the barcode font to generate Code 128.

Hi Ben
This does not help at all. I wonder what can affect the height of the linear barcode.
Is it possible that preinstalled barcode fonts could have side effects?
Is there a regional setting that affects the height of the linear barcode?
Thank a lot for your help!

Yes, you can modify the resolution. Here are the properties for the control:

No, the problem is that we design the label on an office computer and the linear code height is then different on the machine in production!
Is there a resolution parameter to take care of?

Unfortunately, it is difficult to say. I cannot reproduce the issue--when printing to my HP Brother laser, it is never off by the amount of .2 CM. Is there a requirement for 0.5 CM?

Hi Ben

thanks for your answer.
It does not matter if I select a laser printer or another printer, the height of the linear barcode is always less than it should be on a production machine.
Is it possible that some regional settings could affect the height???
Here is some of my used code for the linear Barcode:


LinearCode.BarHeightCM = fHeightBarcode.ToString().Replace(",", ".");



//Do not show the text:
LinearCode.ShowText = false;
//With no border
LinearCode.TopMarginCM = "0.01";
LinearCode.LeftMarginCM = "0.01";

if (this.lstJv[0].CodeLinear_UseCheckCharacter == false)
{
LinearCode.CheckCharacter = false;
}
else
{
LinearCode.CheckCharacter = true;
}
LinearCode.RefreshImage();
imageCode = LinearCode.IndependentEMF;
//Creates the image at defined position:
grfx.DrawImage(imageCode, fPosX +(float)this.lstJv[0].CodeLinear_OffsetX, fPosY + (float)this.lstJv[0].CodeLinear_OffsetY);

What type of printers are being used to print the barcode? You could make sure the drivers are updated for the printers. I am unable to reproduce the error when printing to a thermal or laser printer.
