im getting some errors while running wireshark. im getting all these errors from my network printer what could be the reason for that?
[Expert Info (Error/Checksum): Bad checksum [should be 0x1c224e67]

It probably means that Wireshark thinks the packet, as captured, has a CRC at the end when, in fact, it doesn't. (All Ethernet packets have a CRC at the end - but not all capture devices and mechanisms include the CRC in the packet data.)
We'd have to see one of the packets (preferably in the form of a capture file, rather than a screenshot) to see whether this is a problem in Wireshark or just some case where there's not enough information for Wireshark to determine whether there's a CRC or not.
