怎样检测USB打印机无纸

用C语言 基于三星2410 ARM920 usb芯片是SL811 打印机是hp1150或1160(PCL5e命令) 也可以用hp1020(ACL命令)(不建议)

要求用C编写一个模块(函数)来判断 USB打印机有没有纸,从而给出相应的提示信息

我还要提供一些相关的资料支持! 可速联系本人(有报酬) e_mail : 个人信息保护，已隐藏

只要发送获取端口状态的命令就可以获取到了,命令码如下: buffer[0]=0xA1;buffer[1]=1;buffer[2]=buffer[3]=buffer[4]=buffer[5]=0;buffer[6]=1;buffer[7]=0; /* SETUP数据,GET_PORT_STATUS */ 如果没有纸的话,那么位5的数据应该为1

先谢谢hcn~ 就知道你会回答~ 其实这个我是知道的! 但无论有纸还是没纸每次获取返回的值都是0x18 即:00011000 第五位总是0 即总是有纸~~ 不知道是不是打印机的问题 hp1150/1160都不行

那你将打印机直接接到计算机上面也是这样返回的吗?

是指用bushound发命令给打印机吗?

还是其他方法? 怎么发?

不是的,你只要将打印机的纸取走之后,过一段时间主机就会发送获取端口状态的命令,这时候你可以用BUSHOUND来抓.

哦 ? 是吗? 我抓来看看有没有~

我是没装纸 就把打印机连到电脑上 上面是用busbound抓的

获取状态的命令还没有出来,主机应该会发我上面说的命令码,这种状态要过一段时间主机才会发

请问下 现在开发usb打印机(PCL5e)驱动一般采用哪一款打印机啊? 越便宜越好!

我是等了很久的 ~没发现有其他的命令啊~~

召唤hcn~~~~ 你用Get_Port_Status来获取打印机状态 所使用的打印机是什么牌子型号的啊?? 能支持PCL命令吗? 谢谢~~

我用的是三星的打印机,具体型号记不清了,在获取端口状态的时候要很长时间,可能要几分钟才返回,你就将你的计算机一直处在打印状态的话应该就会出这个现象的

要几分钟啊? 打印个东西要检测这么久那样不合理了~ 哎~~ 还是考虑其他方案算了~
