Programming Notes
Selecting Escape Codes
Select escape codes from Figure B-3, and type in the required escape sequence
combinations. Always use the escape character and the code 1F at the beginning and end
of a file to clear the 1330 to normal character style. Escape code 1F resets escape codes
10 through 1E, and assures that italic, boldface, underlined, or elongated characters set
by another operator will not affect your printed output.
Escape codes 30 through 39 are used in printing bar codes. When escape code 32 is used,
the bar code type is dependent on the interface used.
Helpful Information for Using Escape Sequences
• The codes 10, lC, lD, and 1E have a toggle function. The first entry turns on the
function, and the second entry turns it off.
• A carriage return control code should precede sequences 8C through 90. If it doesn’t,
the 1330 automatically inserts its own carriage return, which may produce an
undesirable printed result.
• Using proportional spacing may cause unpredictable results, because the characters
per inch (CPI) cannot be measured.
• Under LU1, escape code functions will affect print quality, CPI, LPI, and underline
in the same way as SCS control codes.
• Powering off and on the 1330 will change the escape sequence settings back to the
parameter settings selected from the operator control panel.
• Changing parameters from the operator control panel while a print job using
datastream escape sequences is in progress is not recommended. Wait until printing
stops, and then retransmit the desired escape sequences.
• When you want to turn off the italic function in the middle of a line, insert an italic
blank space after the last italic character in the string, before the escape sequence
that turns off the italic function. Inserting a blank allows space for the forward
slant of the last character. Without the space, the character may not be printed
completely. It is not necessary to insert an italic blank at the end of a line.
