用C語言 基于三星2410 ARM920 usb芯片是SL811 打印機是hp1150或1160(PCL5e命令) 也可以用hp1020(ACL命令)(不建議)

要求用C編寫一個模塊(函數(shù))來判斷 USB打印機有沒有紙,從而給出相應(yīng)的提示信息

我還要提供一些相關(guān)的資料支持! 可速聯(lián)系本人(有報酬) e_mail : 個人信息保護(hù)，已隱藏

只要發(fā)送獲取端口狀態(tài)的命令就可以獲取到了,命令碼如下: buffer[0]=0xA1;buffer[1]=1;buffer[2]=buffer[3]=buffer[4]=buffer[5]=0;buffer[6]=1;buffer[7]=0; /* SETUP數(shù)據(jù),GET_PORT_STATUS */ 如果沒有紙的話,那么位5的數(shù)據(jù)應(yīng)該為1

先謝謝hcn~ 就知道你會回答~ 其實這個我是知道的! 但無論有紙還是沒紙每次獲取返回的值都是0x18 即:00011000 第五位總是0 即總是有紙~~ 不知道是不是打印機的問題 hp1150/1160都不行

那你將打印機直接接到計算機上面也是這樣返回的嗎?

是指用bushound發(fā)命令給打印機嗎?

還是其他方法? 怎么發(fā)?

不是的,你只要將打印機的紙取走之后,過一段時間主機就會發(fā)送獲取端口狀態(tài)的命令,這時候你可以用BUSHOUND來抓.

哦 ? 是嗎? 我抓來看看有沒有~

我是沒裝紙 就把打印機連到電腦上 上面是用busbound抓的

獲取狀態(tài)的命令還沒有出來,主機應(yīng)該會發(fā)我上面說的命令碼,這種狀態(tài)要過一段時間主機才會發(fā)

請問下 現(xiàn)在開發(fā)usb打印機(PCL5e)驅(qū)動一般采用哪一款打印機啊? 越便宜越好!

我是等了很久的 ~沒發(fā)現(xiàn)有其他的命令啊~~

召喚hcn~~~~ 你用Get_Port_Status來獲取打印機狀態(tài) 所使用的打印機是什么牌子型號的啊?? 能支持PCL命令嗎? 謝謝~~

我用的是三星的打印機,具體型號記不清了,在獲取端口狀態(tài)的時候要很長時間,可能要幾分鐘才返回,你就將你的計算機一直處在打印狀態(tài)的話應(yīng)該就會出這個現(xiàn)象的

要幾分鐘啊? 打印個東西要檢測這么久那樣不合理了~ 哎~~ 還是考慮其他方案算了~
