Not able to read status #3

Open kubaraczkowski opened 2 years ago

Hi,

The library is great - simple and immediately usable! Nice!

While I am able to print labels on PT-P900W (both usb and tcp), when doing it via network (tcp) the status-reading commands fail. Indeed any call to recv fails. I tried doing everything 'step by step' manually, it seems like the device never sends anything at all to the port. With the USB connection there is no problem at all...

Do you perhaps have any idea what could be going on?

Again - thanks a lot for the great library!

Hi, I also tried to find out how to get the status using a TCP connection, but it seems that TCP mode does not support status feedback. The flowchart for TCP mode (refer to the reference manual on page 48) does not show any status readings, unlike the USB mode.

By accident I once disabled the SNMP protocol on the printer and then also the official apps stopped working. It seems that perhaps the status (e.g. label width) is reported over SNMP rather than TCP.

Any chance you could try to confirm this?
