To check the status of USB ocx driver, the receive buffer of printer will be clear, and the data of next
printing will be clear, when it’s offline.
[

We do not recommend very strong you transmit the data, before you check the status of printer,
when it’s offline.
We recommend you transmit the data, after you check the status of printer, when it’s offline.
Because the data will be lost, if you don’t check the status of printer, and transmit the data
when it’s offline.
