LPR command doesn't print on USB printer
Currently we are working on a processor. There is Linux kernel on it.
The board (you can imagine and assume that it is something like a mother board) has a miniPCI slot. We slot in a miniPCI card with 4 USB ports Then, we plug in a USB printer. Lastly, we turn on the system... - We mount usbdevfs and we successfully get /proc/bus/usb - We make a node for usblp and we get /dev/usb/usblp0 - We install printer module and it is up. - We run the LPD and it is up.:p When we try to print using LPR command, it doesn't print and give us a message states that /dev/usb/usblp0 permission denied.:eek: Then we try to use "cat sample.txt>/dev/usb/lp0" for printing and it is even worst by giving us "Kernel Panic".:( Of cause the printer is detected and it shows us correctly its brand and model. Could you shed a light??:confused: Thanks. |
Got any luck in making USB printer working for your board?
