HiIn my current project we require a barcode(Barcode should be in Code 39 format) to be generated automatically based on a field. As I was never into barcode things I have no experience in this. Hope somebody will help me.
This is what I tried:
I have form.In which I have a field called Number. I have to genarate a barcode for this number field. So I created a computed for display field and gave the value as “" + Number + "”.
After installing the font from IDAutomation.com I was able to generate barcode and when I print the document its displaying properly.
So where is the problem:
When Iam trying to read the barcode in the printed document using a barcode scanner which accepts Code 39 format,its not detecting the barcode.
So am I missing something here?Not sute what to do now?I think someone who has experience in barcodes will help me out!!!
You can create barcodes using Java, You would use LotusScript to call a Java method, the Java method would create an image of the barcode and from there you would have LotusScript pull in the image
I am developing an interface to a Zebra TLP 2824 barcode printer from my Lotus Domino 7.0 based web site. The serial numbers that need to be barcoded will be generated by an agent inside the database that is triggered by the web site. It is possible that the agent/web site could create a file on the user’s computer, i.e. an EPL file that could be sent to the printer.As for creating ,scanning and printing barcodes,i use the following tools:
Could you temporarily change the font for the BarCode field to something ‘normal’ like Courier and see if you are really getting what you expect, that is '123456 for example.
Maybe you need “" + @Text(Number) + "” and use appropriate formatting for the @Text formula.
Yeah I did that and its getting correcting value.Infact at the bottom of the barcode its displaying the value also(No idea why the value is displayed and also Not sure how to turn this feature off/on).
I think the line of real data under the barcode depends on the actual barcode font you’re using. The only other thing I can think of is that when I was using the Code 39 barcode, some scanners would only recognise the barcode down to a certain size. Maybe increasing the size would help. The one I was using actually printed out at about 1cm high
Thank you very much once again. Thats good information.I will increase the size and will see.
The other thing I want to ask is is there any restriction on number of alphanumeric characters(inlcuding “")?Let us say should not be more than 10 charcters including two "” we appeneded?
The only thing I had to ensure was that the barcode did not split across multiple lines, so the size of the barcode will determine the maximum number of characters you can print depending on the paper size.
I use IDAutomation barcodes in my Notes applications, though I use code 128 instead of code 39. I have a symbol scanner and you have to configure the scanner to not include checksum characters for the code 39 fonts. I’ve used the code 39 mod 43 font with checksum and it scanned fine.
One way to verify the scanner is set up properly is to scan a known good code 39 font and see if it reads it. You can also change your text to read the same as a known good sample and see if the symbology is identical. The other thing you may try is changing the number to text, since a barcode really only replaces typing…numbers are treated as text input…you can convert it later if needed.
