Selecting character code table in ESC/POS command - hex
I need print non-english chars on print receipts, use thermal POS receipt printer. Xprinter XP-58III thermal POS receipt printer suppport generic ESC/POS commands.
As I know this should be done by setting character code table. In my case, target code page is 21.
The ESC/POS command for setting Code Page is 'ESC t n' (ASCII) or '1B 74 n' (Hex) where 'n' is page n of the character code table.
I case use of Hex form of command: shold I convert '21' to hex value, or I should use this number without converting, i.e. '1B 74 21'?
Also, where should be added thnis command, right after initialization code?
0x1B 0x40 0x1B 0x74 0x21
I use hex editor to add/edit ESC/POS codes inside the binary file.
EDIT: I solved the issue myself. In order to print any non-english characters on the POS receipt printer, we have to fulfill two conditions: 1) set the correct Code Page, and 2) set the corresponding encoding in receipt file or POS software (same encoding as Code Page). The correct Code Page for this POS printer model is 25 [WPC1257].
I solved the issue myself: the problem was in wrong Code Page set. The correct Code Page for this POS printer is 25 [WPC1257]. We have also set the corresponding encoding in receipt file (same encoding as Code Page).
Page 21 would be "Thai Character Code 11", where 21 is represented in decimal and you need to say "0x15" in binary. Then the command will look like "0x1B 0x74 0x15".
Regarding the command position, the ESC/POS commands are executed in place and affects thereafter in general. There may be no problem it you put it just after the initialization command. Just try.

How does 95cd 21eb fc from Farbrausch's "fuenf" translate into
In 2001 German scene group Farbrausch released a demo called "fuenf" (in your face). pouet.net It contains a 5 Byte executable which could be rather considered a troll approach than a demo. If you run it your hear a weird sound and it could crash your computer. At least it produces a sound. Whatever. The hexadecimal content is: 95cd 21eb fc And the binary representation is: 10010101 11001101 00100001 11101011 11111100 Using xxd I also get the printable chars from the content, which are: ..!.. And that makes me a little confused. Looking up the values in the ASCII table (e.g. here), I get this as a result: •Í!ëü At least the exclamation mark is correct. But how does 95cd21ebfc translate into ..!..? Side note: file -bi fuenf.com sais the encoding is not known: charset=unknown-8bit And iconv -f ISO-8859-1 -t UTF-8 fuenf.com returns Í!ëü Which leads to the assumption, that XXD simply cannot decode the content and therefore just uses default results, like the dot?
First of all, this is not a text file, so looking at it as one makes no sense. It's instructions. Secondly, even if it could be interpreted as text, you would need to know the encoding. It's definitely not ASCII, because that only defines symbols in the range 0-127 (and the 3rd byte here is the only one in that range, which maps to '!'). The "extended ASCII" table you link to is only one of many possible code pages that give meaning to the value from 128-255, but there are many of those code pages. Calling it "extended ASCII" is misleading, because it suggests that ASCII created an updated standard for this, which they did not. For a while, computer vendors just did whatever they wanted with those additional characters, and some of them became quasi-standards by virtue of being included in DOS, Windows, etc. Or they got standardized by ISO (you tried iso-8859-1, which is one such standard).
Boxing captor arduino nano 33 ble : problem excel
(sorry for bad english) I make a project for school : it's a boxing captor made with the Arduino nano 33 ble sense. I only use the accelerometer and gyroscope include on the card. I want to know the acceleration of the boxer's hit in order to deduce the hit power of the boxer. Also the inclinaison of the punching bag will be useful. The captor will be put on the punching bag. The simple programm of accelerometer works but when i try to edit it in order to transfer the data excel i have a error message "Error :DATA < ASCII 10 or >ACSII 200 with PLX-DAQ....". I can't fix it.. can you help me please ? thanks you for your help !! the code is here
The error says that PLX-DAQ won't accept ASCII characters < 10 or > 200. \t, horizontal tab is decimal 9. Make sure you only send characters which are decimal 10-200 in the ASCII table. https://en.wikipedia.org/wiki/ASCII From the PLX-DAQ manual: For simple error checking, PLX-DAQ will indicate an error anytime that a string containing characters < ASCII 10 or > ASCII 200 is received. Values of ASCII 10 (Line Feed) are replaced with ASCII 13 (Carriage Return) prior to processing. I suggest you use comma instead of horizontal tab to separate the values.
Understanding a few iTerm2 default keycode mappings
What are the following used for in iTerm2? For example: ^2 through ^9 and ^- --> Send Hex Code 0x00 .. 0x7f ? ⌥↑ and ⌥↓ --> Send Hex Codes: 0x1b 0x1b 0x5b 0x41... To put it all into one here are the ones in question in a nicely formatted way:
Short answer: For compatibility with old terminals. Real terminals that were dedicated pieces of hardware, not applications in a window system! About the ^0...^9 ones: Terminals would typically use 7-bit ASCII codes, with character codes ranging from 0 to 127, inclusive. Codes 32-126 where used for letters, numbers and punctuation (as they still are in Unicode). 127 was usually the DELETE key (though sometimes that key would send code 8, "backspace" instead, leading to problems which persist in FAQ lists to this day. CTRL-A to CTRL-Z would generate the corresponding ASCII code minus 64, i.e. 1-26. The remaining codes could be a bit harder to generate. CTRL-# usually gave you a 0, but sometimes that was on CTRL-space instead. The 27-31 range was usually at CTRL plus the "ASCII minus 64" position, so for example CTRL-] would give you 0x1D, but there were some terminals where those codes were mapped to CTRL-number instead, and those mappings in iTerm2 seem to be there to cater to people used to such terminals. As for alt-arrow giving 1b 1b 5b 41, that is ESC ESC [ A . Now ESC [ A is a fairly common sequence for the up arrow alone, and prefixing it with an extra escape probably makes Emacs users happy, because it makes the Alt key work as a Meta key for them. I have not looked at the other multi-byte sequences, but I guess they have similar explanations.
How concat multiple fields for a GS1 Data-matrix (BXN) in Zebra Programming Lang (ZPL)
I'm trying to show some data in a GS1 Datamatrix which has field separators (FNC1,GS) pass within the variable to a zpl template. Originally, in ZebraDesigner I couldn't get zpl to allow me to pass the separators within the parameter/variable. The separators would only show as text within the data, not as control characters for the scanner. (I was able to pass the separators as Fix Data, however it needs to work with a parameter). Alternatively, I was hoping to edit the zpl and concatenate the control characters and QR values into one printed data for the Datamatrix. This is zpl using one variable QRCode: (This works but not with passed separators) ^BY208,208^FT448,1123^BXN,8,200,0,0,1,~ ^FH\^FN18^FDQRCode^FS This is using fixed data where FNC1 is \7E and GS is \1D: (This works but doesn't use variables/parameters) ^BY208,208^FT448,1123^BXN,8,200,0,0,1,~ ^FH\^FD\7E188text234567890\1Dmoretext^FS This is my attempt to concat the separators and variables QRData1...: ^BY208,208^FT448,1123^BXN,8,200,0,0,1,~ ^FH\^FD\7E^FN18^FDQRData1^FN22^FD\1D^FDQRData2^FD\1D^FN23^FDQRData3^FS Unfortunately, the QR code only shows the value for the last var QRData3
Escape your field seperator hex codes with an _ (underscore), not with a backslash. And use only one ^FD command like in your second example. For reference see the pages of the commands ^FD, ^FH and ^BX in the Zebra ZPL II Programming Giude As the OP found out, the field seperator _d029 worked for him! This is the hex value (0xD029) for the control character.

Please help identify multi-byte character encoding scheme on ASP Classic page
I'm working with a 3rd party (Commidea.com) payment processing system and one of the parameters being sent along with the processing result is a "signature" field. This is used to provide a SHA1 hash of the result message wrapped in an RSA encrypted envelope to provide both integrity and authenticity control. I have the API from Commidea but it doesn't give details of encoding and uses artificially created signatures derived from Base64 strings to illustrate the examples.
I'm struggling to work out what encoding is being used on this parameter and hoped someone might recognise the quite distinctive pattern. I initially thought it was UTF8 but having looked at the individual characters I am less sure.
Here is a short sample of the content which was created by the following code where I am looping through each "byte" in the string:
sig = Request.Form("signature")
For x = 1 To LenB(sig)
s = s & AscB(MidB(sig,x,1)) & ","
Next
' Print s to a debug log file
When I look in the log I get something like this:
129,0,144,0,187,0,67,0,234,0,71,0,197,0,208,0,191,0,9,0,43,0,230,0,19,32,195,0,248,0,102,0,183,0,73,0,192,0,73,0,175,0,34,0,163,0,174,0,218,0,230,0,157,0,229,0,234,0,182,0,26,32,42,0,123,0,217,0,143,0,65,0,42,0,239,0,90,0,92,0,57,0,111,0,218,0,31,0,216,0,57,32,117,0,160,0,244,0,29,0,58,32,56,0,36,0,48,0,160,0,233,0,173,0,2,0,34,32,204,0,221,0,246,0,68,0,238,0,28,0,4,0,92,0,29,32,5,0,102,0,98,0,33,0,5,0,53,0,192,0,64,0,212,0,111,0,31,0,219,0,48,32,29,32,89,0,187,0,48,0,28,0,57,32,213,0,206,0,45,0,46,0,88,0,96,0,34,0,235,0,184,0,16,0,187,0,122,0,33,32,50,0,69,0,160,0,11,0,39,0,172,0,176,0,113,0,39,0,218,0,13,0,239,0,30,32,96,0,41,0,233,0,214,0,34,0,191,0,173,0,235,0,126,0,62,0,249,0,87,0,24,0,119,0,82,0
Note that every other value is a zero except occasionally where it is 32 (0x20). I'm familiar with UTF8 where it represents characters above 127 by using two bytes but if this was UTF8 encoding then I would expect the "32" value to be more like 194 (0xC2) or (0xC3) and the other value would be greater than 0x80.
Ultimately what I'm trying to do is convert this signature parameter into a hex encoded string (eg. "12ab0528...") which is then used by the RSA/SHA1 function to verify the message is intact. This part is already working but I can't for the life of me figure out how to get the signature parameter decoded.
For historical reasons we are having to use classic ASP and the SHA1/RSA functions are javascript based.
Any help would be much appreciated.
Regards,
Craig.
Update: Tried looking into UTF-16 encoding on Wikipedia and other sites. Can't find anything to explain why I am seeing only 0x20 or 0x00 in the (assumed) high order byte positions. I don't think this is relevant any more as the example below shows other values in this high order position.
Tried adding some code to log the values using Asc instead of AscB (Len,Mid instead of LenB,MidB too). Got some surprising results. Here is a new stream of byte-wise characters followed by the equivalent stream of word-wise (if you know what I mean) characters.
21,0,83,1,214,0,201,0,88,0,172,0,98,0,182,0,43,0,103,0,88,0,103,0,34,33,88,0,254,0,173,0,188,0,44,0,66,0,120,1,246,0,64,0,47,0,110,0,160,0,84,0,4,0,201,0,176,0,251,0,166,0,211,0,67,0,115,0,209,0,53,0,12,0,243,0,6,0,78,0,106,0,250,0,19,0,204,0,235,0,28,0,243,0,165,0,94,0,60,0,82,0,82,0,172,32,248,0,220,2,176,0,141,0,239,0,34,33,47,0,61,0,72,0,248,0,230,0,191,0,219,0,61,0,105,0,246,0,3,0,57,32,54,0,34,33,127,0,224,0,17,0,224,0,76,0,51,0,91,0,210,0,35,0,89,0,178,0,235,0,161,0,114,0,195,0,119,0,69,0,32,32,188,0,82,0,237,0,183,0,220,0,83,1,10,0,94,0,239,0,187,0,178,0,19,0,168,0,211,0,110,0,101,0,233,0,83,0,75,0,218,0,4,0,241,0,58,0,170,0,168,0,82,0,61,0,35,0,184,0,240,0,117,0,76,0,32,0,247,0,74,0,64,0,163,0
And now the word-wise data stream:
21,156,214,201,88,172,98,182,43,103,88,103,153,88,254,173,188,44,66,159,246,64,47,110,160,84,4,201,176,251,166,211,67,115,209,53,12,243,6,78,106,250,19,204,235,28,243,165,94,60,82,82,128,248,152,176,141,239,153,47,61,72,248,230,191,219,61,105,246,3,139,54,153,127,224,17,224,76,51,91,210,35,89,178,235,161,114,195,119,69,134,188,82,237,183,220,156,10,94,239,187,178,19,168,211,110,101,233,83,75,218,4,241,58,170,168,82,61,35,184,240,117,76,32,247,74,64,163
Note the second pair of byte-wise characters (83,1) seem to be interpreted as 156 in the word-wise stream. We also see (34,33) as 153 and (120,1) as 159 and (220,2) as 152. Does this give any clues as the encoding? Why are these 15[2369] values apparently being treated differently from other values?
What I'm trying to figure out is whether I should use the byte-wise data and carry out some post-processing to get back to the intended values or if I should trust the word-wise data with whatever implicit decoding it is apparently performing. At the moment, neither seem to give me a match between data content and signature so I need to change something.
Thanks.
Quick observation tells me that you are likely dealing with UTF-16. Start from there.
