爲Linux安裝虛擬PDF打印機

原文地址:https://lujun9972.github.io/blog/2020/04/11/爲linux安裝虛擬pdf打印機/index.html

今天發現一個 CUPS-PDF 項目,可以爲 CUPS(Common Unix Printing System) 添加 PDF 打印機.

步驟非常簡單:

1. 安裝 CPUS-PDF

   sudo apt install -y cups-pdf
   

2. 根據 CPUS-PDF的文檔說明, 需要設置 cups-pdf 的所有者爲 root,且權限爲 0700

   sudo chown root:root /usr/lib/cups/backend/cups-pdf
   sudo chmod 0700 /usr/lib/cups/backend/cups-pdf
   

3. 重啓CUPS服務

   sudo systemctl restart cups.service
   

4. 可以通過修改 /etc/cups/cups-pdf.conf 的 OUT 參數來設置pdf的輸出位置

   ### Key: Out (config)                                                        
   ##  CUPS-PDF output directory                                                
   ##  special qualifiers:                                                      
   ##     ${HOME} will be expanded to the user's home directory                 
   ##     ${USER} will be expanded to the user name                             
   ##  in case it is an NFS export make sure it is exported without             
   ##  root_squash!                                                             
   ##  on Ubuntu, the cupsd AppArmor profile needs to be updated                
   ##  to match the output path as per instructions in LP:147551                
   ### Default: /var/spool/cups-pdf/${USER}                                     
   
   Out ${HOME}/PDF                                                              
   

5. 然後在CUPS的admin頁面中就能看到一個PDF打印機了

   或者用 lpstat 來查看:

   lpstat -p -d
   

   printer PDF is idle.  enabled since Sat 11 Apr 2020 09:52:10 PM HKT
   system default destination: PDF
   

6. 使用 lpr 打印一個文件試試

   lp ~/dead.letter
   

   request id is PDF-5 (1 file(s))
   

   ls ~/PDF
   

   dead.letter__2_PDF-job_5.pdf
   

7. 最後要注意的是，根據 README 的說明，客戶端選擇打印機時，供應商應該選擇 Postscript, model選擇 Color Printer
