Deepu S Posted October 23, 2019 Share Posted October 23, 2019 I would like to make Orangepi zero to capture USB output destined for a printer in order to log the output from a system. 1 ) Mimic the connected USB printer (so that the machine thinks it still has the original printer attached) 2 ) Capture the output from the machine 3 ) Send the captured output to the printer.

blarki Posted November 21, 2019 Share Posted November 21, 2019 After you've done this, just write something to /dev/usb/lp0 on the host side, again just a standard file. Simplest would be to echo "asdf" >> /dev/usb/lp0 Take care of the permissions for both files, you need your user to be in the lp group and have write permissions. snaptube telegram web Link to comment Share on other sites More sharing options...
