used it before. However the printer will send a response
back to the host.
3. The printer calculates the CRC and compares it with the one
received in the Request Packet. If the CRC is valid, the printer
sends a Positive Response Packet to the Host computer. It
then transfers the ‘Variable Length’ data from the Receive
Buffer to its memory for processing. If the CRC does not
match, and the printer is set up to return a Negative Response
Packet, the following will take place.
a. The printer assumes that the DST. Z-ID, SRC. Z-ID, and
Sequence Number are correct and that the error was in
the variable data.
b. The same DST. Z-ID, printers SRC. Z-ID, and Sequence
Number will be returned back to the host in the Negative
Response Packet.
c. If the assumption in (a) is incorrect, the Host computer can
time-out and retransmit the original Request Packet.
How the Zebra Printer Responds to Host Status
If a ~HS (Host Status) instruction is received by the Zebra printer, the
printer will send back an acknowledgment for the receipt of the
packet. It then sends an additional packet that includes the Host Status
information in the Variable Length portion of the packet.
