barcode-printing

问题 Based on my understanding* of the check digit calculation for Code128 barcodes (which differs radically/drastically from most of the other standard barcode types), my code below is correct. However, I would appreciate a "sanity check" by those who may know better/have some empirical observations/mud from the trenches attached to their trench (or lab) coats. This is my understanding: Each character in the barcode, from the left, is first converted into its ASCII code (IOW, a barcode character

问题 I'm trying print several barcodes using the Zend\Barcode namespace. The problem is reading the manual I can't print more than one barcode. I can't print a echo before the barcode too. How can I print several barcodes and texts together? The code I'm using is similar to this one: use Zend\Barcode\Barcode; $barcodeOptions = array('text' => '123456'); $rendererOptions = array(); Barcode::render( 'code39', 'image', $barcodeOptions, $rendererOptions ); $barcodeOptions = array('text' => '654321');

问题 We use SATO CL412e printers to print labels (3x7), with the label coming from a local SSRS report. Until recently, this setup worked without issue. A few months ago we modified the label, and implemented (new implementation) at one site (Site A). Then a few weeks ago, we pushed the change out to another site (Site B) that had previously been using this label (old version). Since we did this, the label at Site B is... weird. The barcode is quite clearly not right, and all the normal characters

问题 I am trying to generating IDAutomationHC39M for number 50 or 51 the barcode for that gets generated but on scanning I am not able to get the Detail number for that. Same way I am able to create the barcode for 14757 and in that case I am able to scan that barcode properly. How should I scan 2 digit generated Barcodes. Is there some thing I am doing wrong in below code. public void generateBarcode(int id) { if (plBarCode != null) { string barCode = ""; barCode = Convert.ToString(id); System

问题 This is my first post on this website, can't seem to solve the problem. How do I emulate key function Ctrl + B to a barcode so i can scan the barcode with a scanner without pressing Ctrl + B . I've tried reading the ASCII Control Codes ASCII control codes Please help me. 回答1: As one of your tags demonstrates, you are already aware of the code 128 symbology. You will want to use the code128A start code (103) and the same character as a lower case 'b' in code128B (66). Finally, after adding

问题 Currently I'm programming a label-writer (Brother QL-570, if it matters, in Java) to print barcodes with different ID's. The length of the barcode data can vary from ~17 characters to ~3. However, given that I've understood the barcode-concept correctly, the more data - the wider will the barcode become. I'd prefer if all barcodes had the same, contstant size: no matter data-length. (It won't look good if the barcode doesn't fill up the label, nor will it (work) if it's too large) How can one

问题 I have a Zebra Gk420t printer that allows me to make stickers and I need to print an image on them. I read that the images must be in GRF format (pure hex). Someone knows how can I convert the images to GRF format in Linux? I read about Ztools software on Windows, but nothing interesting on Linux... 回答1: Zebra provides a Java API that can convert graphics to GRF. You can use the command line interface to convert images to GRF like so : java -jar ZSDK_API.jar graphic myImage.jpeg -s
