2D Barcodes Not Printing As Squares


I am using Visual C++. When I write encoded text in pdf, it prints in a line (not as a square).

Operating System: Windows

Application: Visual C++

Verify that the data is encoded with an IDAutomation font encoder for the appropriate 2D barcode that you need to generate. Encoding the data 123456 using:

Data Matrix encoder produces:
ANEODOGOBJHPEOBK
AJAIHBAMBJHBOAKK
ANCOPKHKMHKJCONK
AACKIIIGEKIMAKEK

Aztec encoder produces:
JJIEOKGOCAGCAKL
JHNAPILKLIPAKOL
BNPAOCKKKCOAOPJ
BHLPHFDLBBBPLBL


QR Code encoder produces:
AHEEEHAPBDNFEPAHEEEHA
BNFFFNBPFOFKAPBNFFFNB
CONHFBFEBKIODFJPBMCCF
EFFNNFEPILHKIMFNNNKFH
APBBBPAPDEGDDOEINNIEE
HHHHHHHPHHPHPPPPHHPPP

PDF417 encoder produces numeric values similar to:
7777777707070700076763607175442220
7663604301557022076201467013770420
7362207310216111077767252425777510
777777707000707007





When the appropriate font is applied to the encoded data, verify the barcode is properly generated in the application before it is sent to PDF. If possible, perform a test print to physical printer.

If the barcode prints okay to physical printer, then the issue may be the conversion to PDF.

If there is an issue with the barcode print or on screen, verify that the carriage returns and line feeds are not being removed from the application.

If you are receiving only a single line of encoded data similar to AHEEEHAPBDNFEPAHEEEHA, then it is possible the rest of the encoded data has been removed. This is a common problem when encoding data and saving the file as a CSV.


Based on the order information, you own the Universal 2D Font Package Developer License. If you need to encode the data with the C++ header:

Source code for any single encoder, including the C++ Header File, may be provided with the purchase of an Unlimited Developer License and a signed Source Code Agreement.
