CUPS "Waiting for job to complete."

When I print via lp -d brother4 /srv/data2/xfer/TestLabel.3 to a Brother QL-820NWB networked printer, I get the label that I expect. However, the job seems to never be complete in the eyes of CUPS, so I cannot print the next label.

I am migrating some print services from a Windows server to a new UBUNTU server and printing the same file printed on the old Windows server.

I've tried:

Printing in raw format (-o raw) via the command line.
Various drivers for the printer in cups.
Setting a MaxJobTime in /etc/cups/cupsd.conf.
Setting a Timeout in /etc/cups/cupsd.conf.
Text only driver in CUPS.
Raw driver in CUPS.
Spun up a docker container (docker.io/pklaus/brother_ql_web:latest) which prints to the label printer with absolutely no issues.

Of course, I have restarted the service between each change. I can print a .PDF to a different printer on the network with no problems. After three days of this, reading every suggestion I can find and trying most of them, I am stumped.

Does anyone have any advice on how to get CUPS to release the job after it finishes printing?

*** Additional information ***

I changed the log level to collect debugging but have seen no errors.

Any thoughts about what tells CUPS that a job is complete?

You might get a hint by looking at `/var/log/cups/*`. Read `man cupsd.conf`, you can make the logs mote verbose. Which printer driver are you using? Do `lpstat -t`.Access the CUPS (Common Unix Printing Sysyem) GUI by pointing your browser to `http://localhost:631`. You can detect, add, and manage printers from the `Admin` tab, and deal with individual printers from the `Printers` tab. You can set the system default printer.

As it turns out, this https://unix.stackexchange.com/questions/309200/cups-printer-stuck-at-waiting-for-job-to-complete has an answer.

The connection type "AppSocket/HP JetDirect" was the answer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
