[分享]好玩的打印命令lpr、psbook

[Stupid kid]

lpr：lpr submits files for printing.
lpr的manual很短，不过它提供的一个信息确实很不错的，打开http://localhost:631/help看看，这里详细介绍了lpr打印的各种方法。

双面打印功能
e.g.


lpr -o outputorder=reverse -o page-set=even file.pdf ###反向打印偶数页
lpr -o page-set=odd file.pdf ### 打印奇数页


注意：为什么要反向打印，想想应该不难知道，因为，要将原来打印出的偶数页旋转180度后，再放入打印机，而奇数页就是打印在偶数页反面的(呵呵，罗嗦了)；当然转不转180度也不是绝对的，如果你是横向打印的，好像就不需要这样了！


多页打印在一张上：

参数：-o number-up=1,2,4,6,9,16……

打印风格：

这也是很重要的，就是从右往左的顺序，！
参数：-o number-up-layout=……


* -o number-up-layout=btlr; Bottom to top, left to right
* -o number-up-layout=btrl; Bottom to top, right to left
* -o number-up-layout=lrbt; Left to right, bottom to top
* -o number-up-layout=lrtb; Left to right, top to bottom (default)
* -o number-up-layout=rlbt; Right to left, bottom to top
* -o number-up-layout=rltb; Right to left, top to bottom
* -o number-up-layout=tblr; Top to bottom, left to right
* -o number-up-layout=tbrl; Top to bottom, right to left

其他的在浏览器里输入http://localhost:631/help自己吧




psbook:rearrange pages in PostScript file into signatures.

psbook通常和psnup联系起来用，前者用来打乱书的页码以达到打印成手册的目的，同时它也可以定义每一小册的页数；后者用来定义在一页上显示多少张，通常lpr的number-up也能实现这个功能！

psbook只有q和s这两个参数，s用来定义每一小册的页数，要求为4的倍数；
e.g. 需先将pdf文件转换为ps格式的，这个很好办，简单一点就是选择打印的时候选择打印到文件

psbook -s12 inputfile.ps outputfile.ps


输出如下：


[12] [1] [2] [11] [10] [3] [4] [9] [8] [5] [6] [7]
Wrote 12 pages, 690328 bytes


或者：


[12] [1] [2] [11] [10] [3] [4] [9] [8] [5] [6] [7] [24] [13] [14] [23] [22]
[15] [16] [21] [20] [17] [18] [19] [36] [25] [26] [35] [34] [27] [28] [33]
[32] [29] [30] [31] [48] [37] [38] [47] [46] [39] [40] [45] [44] [41] [42]
[43] [60] [49] [50] [59] [58] [51] [52] [57] [56] [53] [54] [55] [72] [61]
[62] [71] [70] [63] [64] [69] [68] [65] [66] [67] [84] [73] [74] [83] [82]
[75] [76] [81] [80] [77] [78] [79] [96] [85] [86] [95] [94] [87] [88] [93]
[92] [89] [90] [91] [108] [97] [98] [107] [106] [99] [100] [105] [104] [101]
[102] [103] [*] [109] [110] [119] [118] [111] [112] [117] [116] [113] [114]
[115] Wrote 120 pages, 37775324 bytes


这就是打乱后的页码，想想为什么……；加上q参数就不会输出上面的页码顺序……

然后你可以用psnup来将页面转到横向，例如：

psnup -2 output.ps > output_nup.ps


或者直接用lpr命令来打印，这样你就可以做自己的小册子了！
