linux 惠普扫描命令 hp-scan 用法详解 |
| 时间：2021-12-21 10:51:03 来源： 作者：phpsrc.com |
安装 hplip 驱动后，惠普打印机相关命令：
扫描颜色模式：gray（黑白）、color（彩色）、lineart（线艺术）
命令格式：
hp-scan -m color //以彩色模式扫描
hp-scan -m gray //以彩色模式扫描
hp-scan -m lineart //以彩色模式扫描
三种模式样式细微区别：
默认 hp-scan 黑白模式扫描出来的单个图片好几M，体积非常大，而彩色、线艺术模式，体积却小的非常多，画质也不受影响，所以建议将 hp-scan 的默认设置为彩色模式。
hp-scan 没有可更改默认扫描颜色模式的选项，可通过 alias 来实现：
alias hp-scan='hp-scan -m color'
将此写入到：~/.bashrc 即可。
