H Experts,

I am working on to develop a printer driver on cups. I am using rastertoepson print filter.
The requirement is when it is found that the printer attached is from other vendor, it will send some junk characters to the printer port and stop original printing.
I have tried many ways to to do this in rastertoepson filter code but not able to fix this.
Please help me how i can do this?

Thanks in advance.
