Combining escape sequences

Combined sequence that specifies the Courier font
Combined sequence that specifies the Coronet font

You can combine PCL emulation commands by linking them if the first 3 bytes of the commands are identical. The combined short form sends the first 3 bytes only once in the string. To combine commands, do these tasks:

Use the first 3 bytes (characters) of the command only once at the start of the command string.
Make the last letter of each command in the string lowercase.
Capitalize the last letter of the string.

With some PCL printers, you can combine multiple commands with the encoding setting. The following command is a concatenation of two other commands:
```
<ESC/>(s<var name = "fontPitch"/>H4099T
```
It is 3 bytes shorter than the long form:
```
<ESC/>(s<var name = "fontPitch"/>H<ESC/>(s4099T
```

Combined sequence that specifies the Courier font

The following sequence specifies the Courier printer-resident font on a Lexmark 644 PCL printer:

<ESC/>&amp;t0P<ESC/>(19U<ESC/>(s0p<var name="fontPitch"/>h0s0b4099T

The following table describes the meaning of each sequence expression in the above example.

Sequence expression	Meaning
(<ESC/>&t0P)	Character codes are interpreted as 1-byte characters (text-parsing method).
(<ESC/>(19U)	Windows 3.0 character encoding.
(<ESC/>(s0p<var name= "fontPitch"/>h0s0b4099T)	A combined escape sequence that comprises the following parts (shown in their non-combined form): `<ESC/>(s0P` specifies constant primary spacing (monospace). `<ESC/>(s<var name="fontPitch"/>H` specifies the number of characters per inch. (See Use of variables in sequences .) `<ESC/>(s0S` specifies the font style as upright (default). `<ESC/>(s0B` specifies a medium stroke weight (default). `<ESC/>(s4099T` specifies the Courier font.

Combined sequence that specifies the Coronet font

The following sequence specifies the Coronet printer-resident font on a Lexmark 644 PCL printer:

<ESC/>&amp;t0P<ESC/>(19U<ESC/>(s1p<var name="fontSize" />v1s0b4116T

The following table describes the meaning of each sequence expression in the above example.

Sequence	Meaning
(<ESC/>&t0P)	Character codes are interpreted as 1-byte characters (text-parsing method).
(<ESC/>(19U)	Windows 3.0 character encoding.
<ESC/>(s1p<var name="fontSize" />v1s0b4116T	A combined escape sequence that comprises the following parts (shown in their non-combined form): `<ESC/>(s1P` specifies proportional primary spacing. `<ESC/>(s1S` specifies font style as italic. `<ESC/>(s0B` specifies medium (default) stroke weight. `<ESC/>(s4116T` specifies Coronet font.
