I use [ESC-POS-.NET) primary with thermal printers but some users still uses imact printers such TM-U220 It prints but images does not print properly and each printing lines are split into two lines.

Definitelly must I don't use [ESC-POS-.NET] with this printers?

I'm familiar with impact printers but haven't tried the library with them. I believe it should work though. Try legacy image printing mode. Try the console.test app included with the source and see what does and doesn't work and report back!

Epson printers has a feature that allow me to store the logo on it's flash memory

This allow me whe use the driver to config if it prints before / after any print job. but with oPos does not work .

My question is about if ican send an oPos command to force the printer to print this logo, because with the TM-U220 model logo does not print properly using PrintImage.
