我正在尝试在连续纸上打印一些长度可变的凭证。问题是打印机拒绝打印超过大约 2300 点（大约 26 厘米或 10.4 英寸）的任何东西，只是假装它不存在。非常轻的代码会触发问题，因此这不是缓冲区问题。打印机还设法读取“打印”命令，并且所有行的格式都完全相同，因此也不是格式问题。这是一个不太简单但几乎可以说明我观点的代码示例：
N //clear buffer
Q10,0 //set paper to continuous mode with 10 points between documents
R0,0 //set reference point
ZT //print from top to bottom

如 EPL2 手册 (http://www.zebra.com/content/dam/zebra/manuals/en-us/printer/epl2-pm-en.pdf) 中所述，第一个“N”之前有一个空行. 将命令发送到打印机时，我也不包括注释。但是，这只会打印到“ASDFQWERTY 2300”行并忽略除此之外的所有内容。非常感谢任何帮助。
