I use the printer zebra printer model zd410 and have designed a label with some keyboard inputs that I want to provide in a ZPL payload, instead of using their software for actually filling out a formula since we already have the data from the application that should print the labels.
The label has these 4 Variable keyboard input with following prompt texts.
barcode = text
reservation = text
department = text
size = text
So by sending
LABEL.ZPL^XA
^XFE:LABEL.ZPL^FS
^XZ
I can print a label with the empty values. I was hoping that I could fill them out by doing something like:
LABEL.ZPL^XA
^XFE:LABEL.ZPL^FS
^department=M3
^size=XL
^reservation=0008734
^barcode=000000000001
^XZ
However this does not work, I was wondering how one would achieve something similar.
What you want to do is possible, but requires the recalled format to contain "placeholders" where the data is to be displayed. In the E:LABEL.ZPL format, you need to define numbered fields like:
^FO150,125^A0N,36,20^FN1^FS
Where the ^FN1^FS is the placeholder for the field #1 data. The ^FN#^FS can be placed in the format anywhere you would normally put a ^FD...^FS data field (text and barcode data).
Then you recall the format and supply the data for the placeholder using:
^XA
^XFE:LABEL.ZPL^FS
^FN1^FDMY VALUE^FS
^XZ
That will substitute ^FDMY VALUE^FS for any occurrences of the ^FN1^FS placeholder in the recalled format.

I am working on Epson dot matrix printer and printing using Esc/p command. But I have problem when i want to print a border of table. The table border will use the extended ASCII :
So I want to use character : 179, 180, 185, 186, etc.... But when I send it to printer, it print strange character. So how to make it work?
I am trying to select character set but it seems still not work. If anyone know about, please let me know.
There are several sets of ASCII tables in the printer.
The printer documentation shows which table is default.
To send extended character to printer, it must be written as hex byte:
data="\xC9" # example extended byte
If you need more precise answer, please let us know which printer you are using, show example of your code.
I have a DBEdit control, connnected to an ADO record set displaying a floating point number. This number has been masked as a currency through the field editor of the record set. This causes a currency sign to be displayed at the front of the number, eg 1.5923432 -> £1.59. I'd like the user to be able to edit the number, and then click a button that pushes the edited number to the database. However, when I get the text content of the box (using strtofloat(DBEdit1.text)) the result produces an error as the text of the dbedit does of course include the currency sign, so cannot be converted to a number.
How can I get the plaintext contents of the DBEdit, (without the currency symbol) without any masking? Would simply deleting the first character from the front of the string be an effective way to do it or is there a simpler way?
I figured it out. You can get the contents of a dbedit with no masking by using: DBEdit1.Field.AsReal or DBEdit1.Field.AsInteger
This will give you the numerical value contained within the dbedit, with no currency signs or commas.
I'm hoping that there are some more options for formatting simple emails formatted as text (not HTML) when using a mailer in a Rails app.
By trial and error, I've found that this markup works in the mailer view (i.e. example_mailer_view.text.erb):
This will be regular text.
==
This text will be formatted in the large, standard HTML Header1 format.
==
The space at the left side of this line will cause it to be smaller text.
>The bracket on the left side of this line will cause it to be indented once.
>>This text is indented twice.
>>This text is indented three times.
_Italicized text_
*This text will be bold.*
Multiple returns...
...between these two lines get compressed into just one blank row.
Is there full documentation of all markup options? Do you know of other markup options that are not listed here? It would be great to have heading2, heading3, etc. Thanks!
Simple text emails are, by definition, simple text. They cannot be formatted. There is no bold simple tyext, nor large simple text, nor italicised simple text. If you see them so, it is because your mail agent is choosing to interpret your plain text emails as if they were written in Markdown; but know that users with other user agents will most likely not see them so. The only way to get rich text emails (i.e. formatted emails) in every email agent (apart from text-only agents such as mutt) is to use an HTML body.
I would like to build invoice text base to have following format:
https://gist.github.com/samnang/9d35a8622af5779a9228
But when I try to render as text format from my controller, then I find out it's very to control how it look because those text are dynamic like company name could be short or long. I don't want to other texts move position depend on something else because those format will be sent to print company to match print out paper.
Is there any examples, gems, or suggestions how to build invoice text base?
You are going to have to truncate some fields to fit into the defined tab area. If you allocate 20 characters of description data, then you need to only allow 20 characters on the output your_text[0..19]
I think working in text for this type of work is going to be overly complex, and you should look at converting the output to pdf to have more control. Take a look at https://github.com/prawnpdf/prawn
I need to print a receipt from my web based apps using dot matrix printer epson tm-u220d (pos printer).
I need to know, should I generate the receipt in html or in plain text ?
I ever saw some commands for dot matrix printer to change the font size, line feed etc .. but I don't remember that commands. if I have to use plain text I need to use that commands. anyone knows where i can get the references ?
Thanks
There is a very good chance that these printers support Esc/P2 which was the Escape codes required to do some formatting on the printer...Here's a link to the RawPrinterHelper...
How are you connected to the printer? Parallel, USB, You may need to add a generic text print driver to allow the means of writing raw escape code sequences to be sent to the printer...for an example, here's an example code that needs to be sent to the printer, depending on how you implement this, to give additional flexibility, the class could parse for simple html codes and re-interpret them as Esc/P2 codes
This will be printed in bold

0x1b0x69This will be printed in bold0x1b0x70
0x1b is Escape, 0x69 is E (Turns on Bold)
0x1b ' " , 0x70 is F (Turns off Bold)
It appears that this printer has a windows driver:
http://www.posguys.com/12_12/Epson-TM-U220_502/
If that is the case, then you can try to print via html. If that doesn't work and you have the ability to create pdf's, you can print the pdf to the windows driver and you should be set. Most pdf generation libraries permit changing the size of the paper, so with some experimentation you can probably make it work. I actually have a web app that does this ... it generates a pdf sized for the printer and the user prints to a label printer from acrobat.
