Solve : What's wrong with printing to a usb printer?? |
Answer» I installed usblp.ko from Linux KERNEL source into my Ubuntu. I checked attribute of /dev/usb/lp0 is 'crw-rw-r--'. I used command 'echo hello > /dev/usb/lp0' to test a printer which was verified successfully at Windows. I got message "bash: /dev/usb/lp0: permission denied". What's wrong with it? What should I do to print to a usb printer?Did you read the documentation? |
