[arm-linux]使用arm驱动hp1020激光打印机

上次讲到交叉编译ghostscript，今天就来看看如何利用gs等软件，在arm开发板上驱动激光打印机，手头只有usb接口的hp 1020 plus，就锁定这款吧。

1）要想Linux支持usb打印机，需要在内核选项中 <*>   USB Printer support

2）在网络上搜索，hp 1020 plus如果想在linux下使用，需要一个叫foo2zjs的驱动程序（http://foo2zjs.rkkda.com/），能否通过交叉编译，只能祈求god bless咯

（1）解压foo2zjs,查看Makefile，直接添加CC=arm-linux-gcc，编译。
（2）编了一会就停止了报错make: *** 没有规则可以创建“all”需要的目标“printer-profile”。
幸运的是此时foo2zjs的可执行文件已经编译完成并可用了。

3）下面的操作在arm开发板上进行：
（1）插上usb打印机
/ # usb 1-1: new high speed USB device using s1r72v17 and address 2
usb 1-1: Product: HP LaserJet 1020
usb 1-1: Manufacturer: Hewlett-Packard
usb 1-1: SerialNumber: JL3ESMZ
usb 1-1: configuration #1 chosen from 1 choice
drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x03F0 pid 0x2B17

（2）mdev -s生成lp0节点，位于/dev/lp0

（3）使用gs生成pbm文件
./gs -q -dBATCH -dSAFER -dQUIET -dNOPAUSE -sPAPERSIZE=a4 -r300x300 -sDEVICE=pbmraw -sOutputFile=test.pbm test.pdf

（4）调用foo2zjs打印pbm文件
./foo2zjs -z1 -p9 -r600x600 test.pbm > /dev/lp0

可以看看foo2zjs的帮助,修改附带参数

/ # ./foo2zjs -h
Usage:
   foo2zjs [options] <pbmraw-file >zjs-file

        Convert Ghostscript pbmraw format to a monochrome ZJS stream,
        for driving the Minolta/QMS 2300 DL network color laser printer
        and other Zenographics-based black and white printers.

        gs -q -dBATCH -dSAFER -dQUIET -dNOPAUSE \
                -sPAPERSIZE=letter -r1200x600 -sDEVICE=pbmraw \
                -sOutputFile=- - < testpage.ps \
        | foo2zjs -r1200x600 -g10200x6600 -p1 >testpage.zm

   foo2zjs [options] <bitcmyk-file >zjs-file
   foo2zjs [options] <pksmraw-file >zjs-file

        Convert Ghostscript bitcmyk or pksmraw format to a color ZJS stream,
        for driving the Minolta/QMS 2300 DL network color laser printer
        N.B. Color correction is expected to be performed by ghostscript.

        gs -q -dBATCH -dSAFER -dQUIET -dNOPAUSE \
            -sPAPERSIZE=letter -g10200x6600 -r1200x600 -sDEVICE=bitcmyk \
            -sOutputFile=- - < testpage.ps \
        | foo2zjs -r1200x600 -g10200x6600 -p1 >testpage.zc

打印效果没的说，就是打印大文件速度慢了点，最快的左边那张也要10s
