Open source barcode image generator in iText

I am looking up on creating our in house Barcode Label Generation software.  Please help me about open source barcode image generator for this project.  Does iText can support such functionality?  Can this also support the ability to pre-select paper size and templates? Can this create a label template with barcode and images?  Does it have access to the database for data?  Has the print output been compatible with various printers?  Most open source barcode image generator is not free.  However I just want to know if iText can support my needs.
