Printer haqida ma'lumot olish uchun lpd/lpr dan qanday foydalanishim mumkin?

Printerni o'z identifikatori haqida so'rov uchun port 515 (lpd protokoli) dan foydalanmoqchiman, lekin boshqa protokollardan farqli o'laroq, lpd kiritish so'rovi yuborilganda printer haqida hech qanday ma'lumotni qaytarmayapti. (Wireshark bilan olingan paketlarga qarab.) Unix-ning lpinfo, lpadmin, lpstat, va hokazolarga qaramasdan, QRM 1179 (LPD protokoli) ni ko'rib chiqdim, ammo printerni 515 (Masalan, "HP2250 LaserJet"). Buni qanday qilishni har kim biladi?

LPD makes a huge assumption about the printer with its PostScript roots. It can manage raw print files to any printer (ASCII inclusive), but makes the assumption the the page definition language (e.g. PostScript) will be consumed and rendered by the printer itself. Though queue status information is often available, the rest is not.

Bundan tashqari, LPD tarixiga o'tadi, albatta printer darajasida emas, balki deamon emas, balki server deamon emas, keyin navbatda/proksi bu boshqa LPD yoki mahalliy (layn) ulamolar joylashtirilgan.

LPD orqali yuqorida va undan tashqarida nima maqsadda bo'lishidan qat'i nazar, nimani amalga oshirishga harakat qilmoqchisiz?
