目前，我正在用標籤編寫器（Brother QL-570，如果它很重要，用Java編寫）來打印具有不同ID的條形碼。條碼數據的長度可以從約17個字符變化到約3個。如何實現條形碼的恆定寬度;不管條形碼數據如何
但是，鑑於我已經正確理解了條形碼概念，數據越多 - 條形碼變得越寬。
我寧願如果所有條形碼都具有相同的恆定大小：不管數據長度。 （如果條形碼沒有填滿標籤，它不會看起來不錯，如果它太大，也不會（工作））
如果標籤的尺寸是固定的（即29mm x 90mm）？你/你的公司是如何解決這個問題的？二維條碼不是一個選項。可悲的是。
如果您必須並排比較不同寬度的條形碼，這看起來有點兒有趣，但是我的公司通過定義每個符號的方式來解決這個問題。位圖並將其擴展至應用程序所需的大小。例如，除Stop之外的每個代碼128符號的寬度爲11像素。我們的「字體」則定義了107個字符，每個字符都是1x11的黑白位圖（PNG）。
如果您對垂直和水平尺寸有很大的控制權，它可以使條碼更容易裝配到空間中。
下面是類似於上面的圖片了一個簡單的例子：

123456789注意，尺寸爲每個字符指定，條形碼可將通常在8或更高的寬度掃描（取決於打印質量）。條形碼中的所有字符都需要相同的寬度。請記住，您的水平安靜區域是條寬度的函數，因此請儘量在標籤上保留至少兩個字符寬度。
我認爲做的最好的事情是你墊的數據，即
123
變爲
0000000000000
剛剛從思考其他地方如何做到這一點，我已經在我以前的日常生活中絕對看到零填充條形碼。我認爲最好的做法是選擇一些您認爲足夠多年的數字，並將您的應用程序編碼爲該數字。如果你最終不得不超越它，那麼，這是一個很好的問題，不是嗎？
我不是條碼專家，但你可以打包嗎？與'00000000000000123'有什麼不同？ – durron597
@ durron597我不這麼認爲，最大數據長度取決於數據庫中項目的數量，17個數據庫是一個近似值，數據庫中有10.000個項目;我不能保證我會有這麼多的東西。也沒有任何保證，我不會有更多的.. – Zar
