We use the free Code 3of9 barcode font you can download from www.barcodesinc.com/free-barcode-font.  We print sheets of barcode labels (3x10).  To get the barcode to print where we wanted it to consistently across the page, we had to use WPRTUNITS-CENTIMETERS-ABS for the WINPRINT-COL-UNITS.

Do you have an example of what the escape sequences would be that you would send to the printer?

Thanks,

David

We don't use escape sequences.  We load the barcode font, move it to the WPRTDATA-FONT, set the column and write the print line.

Here's the main part of the logic...

          INITIALIZE WINPRINT-DATA, WINPRINT-COLUMN.

          MOVE BARCODE-30-FONT TO WPRTDATA-FONT.

          CALL "WIN$PRINTER"

             USING WINPRINT-SET-FONT, WINPRINT-DATA.

          CALL "WIN$PRINTER"

             USING WINPRINT-SET-DATA-COLUMNS, 1, 16, 31.

          MOVE 1 TO WINPRINT-TRANSPARENCY.

          MOVE WPRTUNITS-CENTIMETERS-ABS TO WINPRINT-COL-UNITS.

          MOVE WPRTALIGN-LEFT TO WINPRINT-COL-ALIGNMENT.

          ADD 1.4 TO WS-OFFSET GIVING WINPRINT-COL-START.

          CALL "WIN$PRINTER"

             USING WINPRINT-SET-PAGE-COLUMN, WINPRINT-COLUMN.

                STRING

                      "*"                 DELIMITED BY SIZE

                      WS-BAR-ITEM(SUB)    DELIMITED BY SIZE

                      "*"                 DELIMITED BY SIZE

                   INTO PRINT-LINE

                   ON OVERFLOW CONTINUE

                END-STRING

          WRITE PRINT-LINE BEFORE ADVANCING 1 LINE.

          CALL "WIN$PRINTER" USING WINPRINT-CLEAR-DATA-COLUMNS.

          CALL "WIN$PRINTER" USING WINPRINT-CLEAR-PAGE-COLUMNS.

Then we change back to our text font and print the translation of what's encoded in the barcode.

          INITIALIZE WINPRINT-DATA, WINPRINT-COLUMN.

          MOVE TEXT-30-FONT TO WPRTDATA-FONT.

          CALL "WIN$PRINTER"

             USING WINPRINT-SET-FONT, WINPRINT-DATA.

Thank you very much for this information.

Is BARCODE-30-FONT a field that holds the actual name of the font you are using?

Is  WS-BAR-ITEM(SUB) the field you want the font to create as a bar code?

What is the actual picture of WS-BAR-ITEM?

Thanks,

David

      77  BARCODE-30-FONT        HANDLE OF FONT VALUE NULL.

      01  WS-BAR-ITEM    PIC X(13) OCCURS 5 TIMES.

The program allows for labels to be printed on either 3x10 or 5x10 pre-gummed laser compatible label sheets.  The labels are for books, music, videos and gifts.  The barcodes are ISBN13 (13 bytes) or UPC (12 bytes).  If you need a bigger barcode, just expand he size of the picture.

Near the beginning of the program, we load the font:

          initialize wfont-data, barcode-30-font.

          move zeroes to font-status.

          move "Free 3 of 9 Regular" to wfont-name.

          move BARCODE-30-FONT-SIZE to wfont-size.

          set WFONT-BOLD to false.

          set WFDEVICE-WIN-PRINTER to true.

          set WFCHARSET-DEFAULT to true.

          call "W$FONT"

             using WFONT-GET-FONT, BARCODE-30-FONT, WFONT-DATA

             giving FONT-STATUS

          end-call.

Before we exit the program, we destroy the font:

          IF BARCODE-30-FONT NOT = NULL

             DESTROY BARCODE-30-FONT.

Shane,

    Thanks very much for this. I will try it.

David

if you take another Font then in this example don't forget that when e Checksum is needed for the Barcode you have to calculate it for your own!

In the Example from Shane it is very easy because Code 39 only needs * at the beginning and the end from you Barcode String.
