如何通过 COM1 向我的收据打印机发送 DOS 命令?

How do i send DOS commands to my Receipt printer via COM1?

我目前正在开发收银机软件，但在使用收据打印机时遇到了问题.我需要能够通过 DOS 向打印机发送十六进制命令.

Im currently devoloping a Cash register software, and i ran into an issue using the receipt printer. i need to be able to send hexidecimal commands to the printer via DOS.

到目前为止，我已尝试执行以下操作.

so far i've tried to do the following.

打开 CMD输入复制con:com1输入一个十六进制数按 Ctrl + Z按回车

Open CMD input Copy con: com1 input a hexidecimal number press Ctrl + Z press Enter

根据我所阅读的内容，这应该将十六进制数字作为命令发送到打印机.但它只是将数字作为字符串发送并打印出文本.

this according to what i've read should send the hexidecimal number as a command to he printer. but instead it just sends the number as a string and prints out the text.

有关打印机即时使用的一些信息:TPG A794 收据打印机.可以在此处找到有关打印机的手册:http://www.cognitivetpg.com/downloads/A794%20Spec%20Sheet.pdf

some info on the printer im using: TPG A794 receipt printer. a manual on the printer can be found here: http://www.cognitivetpg.com/downloads/A794%20Spec%20Sheet.pdf

希望有人可以帮助我，因为我已经尝试了所有方法，但似乎没有任何效果.

hope someone can help me out, as i've tried everything, and nothing seems to work.

推荐答案

不要输入Hex-Code.您需要十进制的 ASCII 码.例如:要写0xF，必须转成十进制(15)在 copy con: com1 输入三位数的十进制值 ( 015 ) 时按ALT"(按住它)，然后释放ALT".如果它是具有多个 HexNumber 的命令，则继续下一个值.完成后，按 Ctrl-Z.

Do not enter the Hex-Code. You need the ASCII-Code in Decimal. For example: to write 0xF, you must turn it into decimal (15) after copy con: com1press 'ALT' (keep it pressed) while you enter the decimal value with three digits ( 015 ), then release 'ALT'. Continue with the next value, if it is a command with more than one HexNumber. When finished, press Ctrl-Z.

它可能更容易使用，如果您将命令"写入文本文件，那么您可以将它们复制到 com1:例如:

It may be easyer to use, if you write your "commands" to a textfile, then you can copy them to com1: for example:

copy linefeed com1:

(我没有要测试的串行设备，但它应该可以工作)

(I have no serial device to test, but it should work)

我试过了

copy con bell.txt

然后我输入007(= 0x07，这是一个铃铛)，Ctrl-Z.这给出了一个长度为 1 字节的文本文件

Then I entered 007 (= 0x07, which is a Bell), Ctrl-Z. This gives a textfile with lenght = 1 byte

Type bell.txt

然后会发出哔哔声.

编辑1B"是所谓的Escape-Sequence"(多字节命令)的代码 70"是命令本身，它需要三个参数(n、p1、p2).所以完整的序列是 5 个字节长.您必须用正确的数字替换n"、p1"和p2".您会在串行设备的手册中找到这些(1B"是所谓的Escape-Sequence"(多字节命令)的代码，70"是命令本身，正如您所描述的那样，它需要三个参数(n，p1，p2).所以完整的序列是 5 个字节长.你必须用适当的数字替换n"，p1"和p2".你可以在你的序列号手册中找到这些设备(http://www.cognitivetpg.com/downloads/189-9200250C.pdf)，第 69 页.P1 和 P2 似乎描述了时间，抽屉需要打开/关闭)N 描述了您与哪个抽屉交谈.

EDIT "1B" is the Code for a so-called "Escape-Sequence" (a multi-byte-command) "70" is the command itself and it needs three parameters (n, p1, p2). So the complete Sequence is 5 bytes long. You will have to replace "n", "p1" and "p2" with proper numbers. You will find those in the manual of your serial device ("1B" is the Code for a so-called "Escape-Sequence" (a multi-byte-command) "70" is the command itself and as you describe it, it needs three parameters (n, p1, p2). So the complete Sequence is 5 bytes long. You will have to replace "n", "p1" and "p2" with proper numbers. You will find those in the manual of your serial device (http://www.cognitivetpg.com/downloads/189-9200250C.pdf), Page 69. P1 and P2 seem to describe the time, the drawer needs to open/cose) N describes which drawer you talk to.

EDIT2每个命令创建一个文件.例如.open1.bin"close1.bin"等.按照我的第一个答案中的描述创建它们.您应该首先尝试使用简单"命令(单字节命令)来验证是否可以正常工作.要执行这些命令，请使用 copy open1.bin com1: 将它们发送到 com 1.对于多字节命令，使用 copy con: file.txt 创建它们，同时按住alt"输入第一个值，释放alt"，再次按下并按住第二个值，依此类推.

EDIT2 create one file per command. eg. "open1.bin" "close1.bin" etc. Create them as described in my first answer. You should first try with "simple" commands (one-byte-commands) to verify, that this works ok. To execute the commands, send them to com 1 using copy open1.bin com1:. For multibyte commmands create them with copy con: file.txt Enter first value while you keep "alt" pressed, release "alt", press it again and keep it pressed for the second value and so on.
