Hi Guys!
I can print text from android tablet to a pcl5 printer. I use the usb library for this, I can connect a printer by usb, and send pjl and pcl commands. All thing goes well.
But I have a new tablet on what I can't connect to the printer. Even more, I use a program, called USB device info. This program lists the connected usb devices in two separated columns: one column shows devices known by android, the other column shows devices known by kernel. Here is my question: my printer is listed in the kernel column, but not in android column.
My connection code starts with lines like this:
Dim usbdevices() As UsbDevice
usbdevices = manager.GetDevices
but usbdevices is empty, because android doesn't showed it.
Can I connect to such a device what is known only by kernel? What would be the reason, that android doesn't know an usb device? I think it is not because I want connect a printer, this could be any type of usb device.
