Query about Printing Unique Pallet Labels 追蹤
I was planning to use Bartender to print pallet labels.
The situation is following: I have a markem Imaje 2200 Series printer on a conveyor where pallets are passing by. Now every pallet MUST be labeller with a unique pallet number/barcode and certain other details identifying the pallet.
The information on what has ot be printed can be provided in an SQL table or via .NET api. My questions are following:
1. Does bartender support drop-on-demand sort of printers where print happens periodically based on a job that has been created every-time a new item passes in front of the printer. This is different from typical label printers where the print is always manually triggered.For printers like Markem Imaje 2200, when I print a label from the menu in bartender, what would typically happen? Would the printer start printing as if a pallet was already there or it would wait for next pallet to arrive and then issue that print? What if the user issues print command multiple times, would the printer print last one or FIFO when the pallets eventually passby?
2. In the above situation, Does bartender have the capability to Spool the prints. So if the SQL table has 10 rows, it would keep printing each for every pallet until the last pallet goes through. The SQL table would have new rows coming in and bartender would keep printing rows allowing to create a buffer/spool. Is this something possible with bartender?
3. If the above doesnt work out, then I believe I would have to setup external logic such that we trigger a print exactly when required and all buffering/sensing pallet flow would be managed outside bartender.
Looking forward to hearing your experience.
