Bar Code Printing In Sap

Questions for Bar Code Printing in SAP 1. Can we print bar codes in SAP only from ZEBRA printers ? 2. I had read that bar code printing is enabled in SAP and only needs to configure device/printer for that. Does this mean that we can use our existing HP 2300 or like printers to print bar codes without any ZEBRA like printers and the printed bar codes are readable through any reader ? 3. Are there any specific steps to print bar codes from SAP (from within Smartforms) including data fetch and printer configurations. 4. What is the process or method for reading data in bar code form into sap ( as far as I think that we can upload the txt file created from reader and upload it to SAP ). Can we do this without uploading TXT file i.e. directly reading from bar code reader into SAP. In other means what are the normal ways to read bar codes data into SAP. Furthermore, we have taken a zebra Z4M plus printer from one of vendor on trial basis but even after following the recommended steps as mentioned in the config. manual we are unable to print any thing on bar code printer from within SAP. I do agree that we can print bar codes from excel or from outside SAP but we wanted to print it out from within SAP and we think SMARTFORM is an easier way as compare to SAPSCRIPT (although we don't have any idea of printing bar codes from SAPSCRIPTs). About reading from bar code reader .... yes we know that we have to read the bar codes into a ASCII or text file but in that case we need to write a ABAP program to upload that information into SAP to do MIGO (in our case) and for that we also need to fill in certain other information into that text file after reading bar codes ....?? is there any other simpler way of doing this ??? We are able to print barcodes from smartforms. Doing this way, we print barcodes on laser printers. We are also printing from sap to zebra printers using two ways: 1. Download the data to an excel sheet, then creating a macro that opens the printer port and sending the commands to the printer through this "file". All this is done via vb script provided with excel).. 2. The second way is creating a vbscript (an ascii file from sap) with the printer commands and then runing it using ws_execute. You need a barcode reader to read the barcodes, and this scanner acts like a keyboard, it sends the data scanned to the active field on screen. (which might be a notepad, word, excel or an input field or ... ). Back to your problem:

1. We're using Zebra 2746-e (Eltron) to print labels that have some barcodes in their design. There are several approaches to solve this problem. We've decided to work with the programming language of the printer (EPL-2), because we use the zebra printers from SAP or from other windows applications. Our solution was to develope function module that creates an ascii file (a vbscript file) and then use the ws_execute to run wscript with this file. The vbscript just opens the port for output and sends a sequence of writeline, each of them with a command to the printer. After all the commands were sent to the printer, we close the port . Just note that the port acts the same as a file. This is an EXAMPLE of the visual basic script code; Set fs=CreateObject("Scripting.FileSystemObject") Rem send the output to COM1 port. Set a = fs.CreateTextFile("COM1:",True) Comilla = Chr(34) a.writeline "O" a.writeline "ZB" a.writeline "" a.writeline "" a.writeline "" a.writeline "N" a.writeline "" a.writeline "" a.writeline "q800" a.writeline "Q635,24+0" a.writeline "R32,24" a.writeline "S3" a.writeline "D8" a.writeline "ZT" a.writeline "" rem this is an example of barcode ean128-ucc a.writeline "B126,429,0,1E,3,3,61,B,""011234567890123410051215""" rem this is an example of barcode 3 of 9 rotated a.writeline "B10,495,3,1,3,3,49,B,""01234567""" a.writeline "" a.writeline "" a.writeline "P1" a.writeline "" a.Close We've send this code to an ascii file or as part of a macro to be run within an excel sheet. We have succeed in both cases. The zebra printer is created as local to the computer running the vbscript. We haven't been able to share the zebra printer so other people in the network can use it. And the zebra printer isn't installed as a SAP printer (we aren't using sap spooler to send jobs to the zebra). Another Note: zebra 2746 comes with a software bar-one (or something like that) that allows you to design the barcode label in a wysiwyg way

If my memory isn't failing, I think that I've read something about controlling zebra printers from smartforms in service.sap.com, but I haven't explored this possibility. 2. From 4.6c on, you can use smartforms to print barcodes without buying any barcode.dll software nor hardware extention like Bardimm on any laser/inkjet printer (Please Note that I haven't mentioned Zebra printers here!). To do this, you have to create a smartstyle -> character format with the desired barcode font (defined within sap). Then in the smartform, create a window, put the field and associate it the character format. That's all (I mean, that's all we do at least :-). I think, you have to consider the barcode specifications before sending the barcode value to the smartform (Just an example, if you're using 3 of 9, the code should start and end with an asterisk - '*' -) We're printing an interleaved 2 out of 5 barcode in our invoices due to a legal requirement, and we did it this way. 3. If you have a barcode scanner, then you should not need reading the barcode into an ascii file to get the data read in an standard or custom screen field. You can read it directly to the field you want. (unless... you have complex data coded in the barcode for example if you're using an ean-ucc 128 compliant code and you're sending several fields in a single code ... In this case, an interface is almost mandatory because you must interpret the data fields according to the ucc standard, split the code into several fields .... and .... pure programming logic ). To put it clear: if you have to read, for example, a barcode that holds the legal number of an invoice using a barcode scanner and this number should be sent to migo-> bktxt then you don't need an interface. The scanner itself acts like a fast operator entering the characters using a keyboard and filling in the field. We're reading barcodes in several places (when we finish each pallet, when we receive an invoice, and so on. Each case is a different screen. We arent using an ascii file to read these barcodes. Furthermore, we read the invoice legal number into migo bktxt field (Head Text)
