是否有命令獲取現有列印機的型號/驅動程序/ppd 以用於“lpadmin -m”?
我正在設置一台伺服器的 CUPS,使其具有與另一台 CUPS 伺服器相同的列印機集。我通常住在 CLI 中,它是一長串列印機,所以我想知道這可以做得多麼簡單。查看命令的文件,我發現我可以像這樣添加列印機:
lpadmin -p $printer_name -E -v $printer_location -m $printer_model
我可以得到
$printer_name
s 和$printer_location
s :lpstat -v
但我似乎找不到可以告訴我
$printer_model
每台列印機的命令。我很想通過抓取來破解它http://localhost:631
以curl
獲得人類可讀的模型,然後匹配lpinfo -m
以得到適合的東西lpadmin -m
,但我希望有一些更傳統的東西。
沒有獲取已安裝列印機驅動程序的正常命令。
這是基於 meuh 使用庫的建議列出
lpadmin -m
可接受的 ppd 規範(相對路徑drv:///
和/或URI)的解決方案:gutenprint*://
# hpcups and gutenprint put their version in the model names. That means # that if you install a printer then update the drivers, the model of the # printer won't match with those available listed by `lpinfo -m`. So, we'll # strip the version. strip_versions() { sed -E 's/(, hpcups|- CUPS\+Gutenprint).*//' } # Using @ as a custom field delimiter since model names have whitespace. # `join` is to match the printers' model names with those of the available # drivers. join -t@ -j2 -o 1.1,2.1 \ <( ruby -r cupsffi -e ' CupsPrinter.get_all_printer_attrs.each do |name, attrs| puts "#{name}@#{attrs["printer-make-and-model"]}" end ' | strip_versions | sort -t@ -k2 ) \ <(lpinfo -m | sed 's/ /@/' | strip_versions | sort -t@ -k2) | # We may get multiple ppd specs per printer. For a few printers, I'm # getting a relative path from the system model directory and either a # drv:/// uri or a gutenprint.5.3:// URI. We'll filter out all but the # first per printer. awk -F@ '!a[$1]++' | # Change the @ column delimiter for whitespace and align columns. column -ts@
cupsffi
是一個可以安裝的 ruby gemgem install cupsffi
。
您可能能夠從 ppd 文件
/etc/cups/ppd/
和(受保護的)文件中 grep 某些內容/etc/cups/printers.conf
,但是 cups 庫有一個 Python 介面pycups
,可以與伺服器對話以獲取資訊。例如,#!/usr/bin/python3 import cups conn = cups.Connection() printers = conn.getPrinters() for printer in printers: p = printers[printer] print(printer, p['printer-make-and-model'])
返回的列印機字典有條目:
printer-make-and-model
printer-is-shared
printer-type
device-uri
printer-location
printer-uri-supported
printer-state-message
printer-info
printer-state-reasons
printer-state
。我pycups
在 rpm 包中找到了python3-cups
。
