Using the example above, the fixed text header "GSE Scale Systems" is to appear on every printed ticket.
Since this is the first element of the transmit table, begin entering the header text at P1000.
To enter text using the alpha keypad or serial port, simply key in the desired character(s) and press
[ENTER].
To enter text using the scrolling method proceed as follows:
1. Press [F1] to scroll through the character set.
2. Once the desired character is displayed, press [F5] to shift right to the next character position.
3. Repeat steps 1 and 2 until the entire name is displayed ending at step 1.
4. Press [ENTER] to accept and insert the entered text into the transmit table.
Note: Pressing [F4] will scroll backwards through the character set.
Pressing [F3] will shift left, or backspace.
Pressing [CLR] will delete an entry in process.
To enter text using the [ALPHA] key proceed as follows:
1. Press the [ALPHA] key if the ALPHA icon is not displayed.
2. Press the key, which contains the desired character on the numeric keypad.
3. The character will automatically advance depending on the time limit set at P841 or press the desired
key for the next character.
4. Repeat steps 1 and 2 until the entire name is displayed ending at step 1.
5. Press [ENTER] to accept and insert the entered text into the transmit table.
Note: Pressing [0] and [CLR] or [F3] simultaneously will also backspace through the transmit table.
Note that the text appears in the custom transmit table exactly as entered.

Control codes are generally considered to be non-displayable ASCII characters such as a carriage return
<CR > or line feed <LF>. Since you cannot see these characters, control codes must be entered using their
ASCII value as shown below. Refer to the ASCII chart in Appendix A for a complete list of control codes.
Having entered the fixed text for the header line of the ticket in the previous example, we must next account
for the blank line that follows and position the print 'cursor' at the beginning of the third line (the 'cursor' now
resides at the end of 'Systems'). Positioning the 'cursor' requires use of special non-displayable characters
call control codes. Our example requires the use of two common control codes - carriage return <CR> and
line feed <LF>.
A carriage return <CR> positions the 'cursor' to the left-most position of the current line.
A line feed <LF> moves the 'cursor' down one line without moving it left or right.
Therefore, to move the 'cursor' from the end of the first line to the beginning of the third line we must
transmit a carriage return and two line feeds <CR><LF><LF>. Similarly, a <CR> and <LF> will be required
after each subsequent line as illustrated below. Note the form feed <FF> at the end of the ticket. This is
another control code, which is used to advance the printer paper to the top of the next ticket.
