Nat*_*han 3 c# printing image bitmap zebra-printers
我写了一个库,它从一些用户输入创建一个位图图像.然后使用斑马打印机打印该位图.我遇到的问题是斑马打印机打印的图像上的一切都非常微弱和模糊,但如果我将位图打印到激光打印机,它看起来很正常.有没有人遇到这个,如果是这样,他们是如何解决它的?我已经尝试了几乎所有我能想到的打印机设置.
更新了我如何创建位图图像的代码.
public static Bitmap GenerateLabel<T>(T obj, XmlDocument template)
{
try
{
int width = Convert.ToInt32(template.SelectSingleNode("/LABELS/@width").Value);
int height = Convert.ToInt32(template.SelectSingleNode("/LABELS/@height").Value);
if (obj == null || height <= 0 || width <= 0)
throw new ArgumentException("Nothing to print");
Bitmap bLabel = new Bitmap(width, height);
Graphics g = Graphics.FromImage(bLabel);
XmlNodeList fieldList = template.SelectNodes("/LABELS/LABEL");
foreach (XmlNode fieldDetails in fieldList)
{
//non important code...
g.DrawImage(bBarCode, field.Left, field.Top);
using (TextBox txtbox = new TextBox())
{
// more non important code...
Rectangle r = new Rectangle(field.Left, field.Top, field.Width, field.Height);
txtbox.DrawToBitmap(bLabel, r);
}
}
return bLabel;
}
catch (Exception ex)
{
throw new Exception("Unable to create bitmap: " + ex.Message);
}
}
