https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=253232 --- Comment #2 from Brock Williams <brock@cottonwoodcomputer.com> --- We are not using cups, and I verified it is not installed on the test system. I tried a usbdump but not really sure what to look for. The output looks the same to me on the ones that work and that don't: 09:12:29.188729 usbus0.2 SUBM-CTRL-EP=00000000,SPD=FULL,NFR=1,SLEN=8,IVAL=50 09:12:29.194644 usbus0.2 DONE-CTRL-EP=00000000,SPD=FULL,NFR=1,SLEN=0,IVAL=50,ERR=0 09:12:29.194684 usbus0.2 SUBM-BULK-EP=00000001,SPD=FULL,NFR=1,SLEN=12,IVAL=0 09:12:29.196558 usbus0.2 DONE-BULK-EP=00000001,SPD=FULL,NFR=1,SLEN=0,IVAL=0,ERR=0 09:12:29.457889 usbus0.2 SUBM-CTRL-EP=00000080,SPD=FULL,NFR=2,SLEN=8,IVAL=0 09:12:29.465653 usbus0.2 DONE-CTRL-EP=00000080,SPD=FULL,NFR=2,SLEN=4,IVAL=0,ERR=0 vs 09:12:32.490567 usbus0.2 SUBM-CTRL-EP=00000000,SPD=FULL,NFR=1,SLEN=8,IVAL=50 09:12:32.496664 usbus0.2 DONE-CTRL-EP=00000000,SPD=FULL,NFR=1,SLEN=0,IVAL=50,ERR=0 09:12:32.496703 usbus0.2 SUBM-BULK-EP=00000001,SPD=FULL,NFR=1,SLEN=12,IVAL=0 09:12:32.498943 usbus0.2 DONE-BULK-EP=00000001,SPD=FULL,NFR=1,SLEN=0,IVAL=0,ERR=0 09:12:32.600296 usbus0.2 SUBM-CTRL-EP=00000080,SPD=FULL,NFR=2,SLEN=8,IVAL=0 09:12:32.608505 usbus0.2 DONE-CTRL-EP=00000080,SPD=FULL,NFR=2,SLEN=4,IVAL=0,ERR=0 We also determined that if we send data directly to the /dev/usb/0.2.1 device as opposed to /dev/ultp0, it prints reliably. We intend to use that as a workaround for the time being. FWIW, we have tried multiple computers, multiple printers, and multiple brands of usb->parallel adapters, and so far, all of the combinations have had the same problem.
