di ata tayo nag kaintindihan.. from 877a uC yang commands ang isesend mo sa serial port from uC to Printer...

so i program mo yung uC mo with the esc format para mabasa nang serial printer mo...

baka gusto mong magsubok ng gumamit ng PIC mcu with usb host at gamitin ung usb printer driver from Microchip. Pls. check Microchip Applications Library for more details.
