Dot Matrix - SAPWIN and EPESCP9

I am using 9 pin epson printer to print smartform, SAP server is unix, print server is windows ( SPrint installed). connect using SAP protocol.

I have problem as following:

using EPESCP9 device type, font size was correct but no border(no matter how thick I made it in smartforms), no image and half page(custom paper size) is not working.

using SAPWIN or SAPWIN5 or SAPWINCF, border, image, half page is working, but font always defaulted to 1 font size (it is big) no matter what change I made to adjust it to smaller size. I have tried using true type fonts but it is not working too .

I think SAPWIN is the way to go, since I only have a font size problem there, any suggestion?(In the print preview the size of fonts is correct, it is just in the print result that the font is defaulted to bigger size)
