I am a POS system developer. I uesd to use Clipper for those project.
Starting from last year I almost finished the upgrading project from DOS Clipper to VFP6.0. Everything went smoothly except controling Receipt printer (Epson TM-T88 Themal Printer),which is mostly contoled by DOS command such as bold letter or printing barcode etc.

I tried send out command in the VFP prg file but it didn't accept printer control languages and just print out whtever specific code itself.

Is there any VFP professional who can help me out?

Thank you for your attention!
