💖 usb_printerid — the little USB printer ID gossip session 💖

okay so bestie, welcome to usb_printerid from the General Commands Manual section — she's a tiny lil one-trick pony and honestly? her trick is so useful. She prints the ID of the printer on a USB port. That's it. That's the whole job. And she ate. 💅

---

✨ SYNOPSIS ✨

usb_printerid [options] /dev/usb/lpNNN

yeah. that's the whole vibe. you hand her [options] if you want, plus the device path /dev/usb/lpNNN, and she goes to work. no cap. 🫶

🌸 DESCRIPTION 🌸

So like, here's the tea: usb_printerid prints the identification of the printer on a USB port. How does she do it, you ask? She slides in using the ioctl control LPIOC_GET_DEVICE_ID and asks the printer to introduce itself. Iconic behavior, honestly. The printer spills its whole government name. 🔥

🦋 EXAMPLES 🦋

Bestie, this is the moment. The main character scene. You print the USB info before and after downloading the firmware — and you get to watch the printer's lil glow-up happen live. 😭

# usb_printerid /dev/usb/lp0
GET_DEVICE_ID string:
MFG:Hewlett-Packard;MDL:HP LaserJet 1020;CMD:ACL;CLS:PRINTER;\
DES:HP LaserJet 1020;

# cp /var/lib/foo2zjs/firmware/sihp1020.dl /dev/usb/lp0

# usb_printerid /dev/usb/lp0
GET_DEVICE_ID string:
MFG:Hewlett-Packard;MDL:HP LaserJet 1020;CMD:ACL;CLS:PRINTER;\
DES:HP LaserJet 1020;FWVER:20050309;

See that?? FWVER:20050309; showing up at the end after the firmware drop?? that's the printer saying "new me, who dis". Obsessed. 🎀
