changes in 90° clockwise-rotation mode, the relationship between vertical and

horizontal directions is reversed.

• In page mode, vertical and horizontal directions are based on the character orientation.

• When characters are enlarged with different sizes on one line, all the characters on the

[Notice] • This command is effective only in page mode.

• If the [( nL + nH × 256) × (vertical or horizontal motion unit)] exceeds the specified

printing area, this command is ignored.

• The horizontal starting buffer position does not move.

• The reference starting position is that specified by ESC T.

• This command operates as follows, depending on the starting position of the printing

area specified by ESC T:

_ When the starting position is set to the upper left or lower right, this command sets the

absolute position in the vertical direction.

_ When the starting position is set to the upper right or lower left, this command sets the

absolute position in the horizontal direction.


• The GS P command can change the horizontal and vertical motion unit.

However, the value cannot be less than the minimum horizontal movement amount, and it

must be in even units of the minimum horizontal movement amount.

[Description] 定义Flash 位图：

· n 指定所要定义的Flash 位图的数目。

· xL、 xH指定Flash 位图的横向点数( xL + xH × 256) × 8。

· yL、 yH指定Flash 位图的纵向点数( yL + yH × 256) × 8。

[Notice] · 频繁执行该指令能损坏Flash 存储器，推荐每天最多写Flash 10次。

· 该指令删除所有的以前由该指令定义的Flash 位图，打印机不能对上一次定义的多

幅位图中的一个进行重新定义，在这种情况下，必须重新发送所有的数据。

· 由于在处理该指令的过程中，打印机处于忙状态，它向Flash 中写数据并且停止接

收其他指令，因此，在该指令的执行过程中，禁止向打印机发送其他命令，包括实

时指令。

· Flash位图是由指令FS q定义存储在Flash存储器中并用指令FS p打印的位图。

· 在标准模式下，该指令仅在行首时有效。

· 从 FS 到 yH 的七个字节数据作为命令数据处理，不是图形数据的一部分。

· 当位图数据字节数超出由它左边的xL、xH、yL、yH定义的Range，则打印机只处理

xL、xH、yL、yH定义的Range的数据。

· 在第一组Flash位图里，当xL, xH, yL, yH中任何一个参数超出定义的Range时，该

指令无效。

· 在下载多幅位图时，如果打印机处理xL、xH、yL、yH超出定义的Range，则打印机

停止执行这条指令。命令中在此之后的位图无效，在此之前的位图有效。

· d是定义的位图数据，在数据中相应位为1表示打印该点，为0表示不打印。

· 这条指令定义了 n 幅Flash位图。每个位图的序列号从 1 依次增加，因此，第一个

数据组 [xL xH yL yH d1...dk] 是Flash位图 1 的数据，最后一个数据组 [xL xH yL

yH d1...dk] 是Flash位图 n 的数据。在用FS p 指令打印位图时，也是如此。

· 定义一幅Flash位图的数据由 [xL xH yL yH d1...dk] 组成。因此，当只有一幅位图时，

n = 1。打印机占用Flash存储器字节数如下：

[位图数据字节数：（ xL + xH × 256）×（ yL + yH × 256）× 8] + [头信息：4]

· 在打印机里Flash下载空间最大为64K bits ( 8K bytes)，该指令可以定义多幅Flash位

图，但不能定义一幅大小超过64K bits的位图（不同的打印机下载空间也不相同，

请参照打印机配置信息）。

· 在写Flash 之前，打印机立即处于忙状态。

· 在处理该指令的过程中，打印机不传送状态也不执行状态查询。

· 在宏定义的过程中接受到该指令，打印机将结束宏定义，开始执行该指令。

· 如果一幅Flash位图被定义，执行ESC @命令、复位和关闭电源不能将其擦除。

· 该指令只是定义Flash位图，不执行打印，打印Flash位图由FS p指令执行。

附录附录附录附录 B：：：：打印模式及其转换打印模式及其转换打印模式及其转换打印模式及其转换

B.1 综述综述综述综述

打印机有两种工作模式：标准模式和页模式。在标准模式下，只要打印机行缓冲区满或者接收

到打印或进纸指令，打印机就打印并进纸。而在页模式下，所有的打印数据和进纸指令都被存储在

指定的内存空间里，打印机不执行任何操作。直到接收到一个ESC FF 或 FF 指令，打印机将会把

打印区域所有内容都打印出来。

例如：当打印机在标准模式下接收到“ABCDEF”<LF>时，它立刻将“ABCDEF”打印出来，

并进纸一行。而在页模式下，打印机将“ABCDEF”写到内存中的打印区域中，接下来的打印数据

放在打印区域的下一行。ESC L 指令将打印机切换到页模式，在此之后的所有数据都在页模式下

处理。这样执行ESC FF指令能将接收到的所有数据打印出来，而执行FF 指令不但能将接收到的所

有数据打印出来，而且还将打印机切换到标准模式。执行ESC S 指令也能将打印机切换到标准模

式，但是它不打印在页模式下接收到的数据，并且将这些数据清除掉。

1）有些命令（如：ESC SP、 ESC 2、ESC 3、和 FS S）既可以用在标准模式下又可以用

在页模式，而且它们的参数也相同。但是在两种模式下的设置是独立的，它们被分别存储

起来。

B．．．．3 打印区域设置打印区域设置打印区域设置打印区域设置

1）打印区域是由ESC W指令设置的。如果在接收到ESC W指令之前所有的打印和进纸操作

都已经完成，则打印机以左边（当你面对打印机时）作为打印区域的坐标原点（x0，y0）。

矩形打印区域的宽度（dx 点）在 x 向（垂直于进纸方向）从坐标原点（x0，y0）向右扩

展，高度（dy 点）在 y 向（进纸方向）。如果没有用ESC W设置打印区域，则打印区域

采用Default。

2) 打印机在打印区域和打印区域方向（由ESC T指令设置）设置之后，接收到的打印数据将会

在打印区域内按照图B.2所示位置排列，A点为打印区域的起始位置，这是个Default。（当

一个字符被打印时，A 点作为基线）

打印数据中的下载的位图或条码数据以当前位置作为其左下角（图B.3中的B点），与基线

对齐。

3) 在接收到一个包含有进纸的命令（如：LF 或 ESC J）之前，如果打印数据（包括字符间

距）已经超出打印区域，则打印机自动进纸一行（进纸多少，取决于由ESC 2和ESC 3设

置的行高），同时打印位置移到下一行行首。

4) 默认行高是4mm（约1/6英寸），相当于纵向上32点。如果在下一行的打印数据中含有在纵

向上放大超出2倍的字符，或者位图占用2行甚至更多行，以及条码比正常字符高时，打印机

进纸量不能满足需要，造成打印的字符和上一行打印的字符叠加。为了避免这些，可以增加

行高。

例如

当打印一个6个字节高度的下载位图时，用下边公式：

{纵向点数（8×6）- 打印区域起始位置的进纸点数（24）} × 纵向移动单位（203/203）

= 24，也就是说，要打印出完整的位图，需要在打印区域起始位置的基础上将打印位置下

移24点。

用下列命令：

ESC W xL, xH, yL, yH, dxL, dxH, dyL, dyH

ESC T n

ESC 3 24 �设置新的行高

LF �走纸一行

GS / 1

ESC 2 �将行高恢复到Default
