Hello,
I need to translate a printer driver from parallel to USB. I have a Star TSP
143, which supports ESCPOS. I have been using RXTX to talk to the printer
over /dev/lp0.
My code already retrieves the status of the printer, which tells me if it is
out of paper and forth.
But I am not able to get the printer to print. Therefore I have sniffed the
USB port once when printing with CUPS. And once when talking to it via
javax.usb.
The difference between CUPS and javax.usb is the interrupt-events when
printing with CUPS. It seems to me that the kernel usblp-Modules does use
interrupts to send data to the printer.
Is the a way to tell javax.usb to use interrupts or am I doing something
wrong in general?
The Code:
