Short description of the document printer
The document printer has a document printing point with which single documents,
multiple documents (sets of forms) and passbookscan be processed. The printer
canalso be equippedwitha magneticstripereader (MSR), a magnetic ink card rea-
der (MICR) or a single sheet feeder as an option.
Document printing point
The term ’document’ includes all single documents, for example, cheques, unprinted DIN A4 papers (blank documents), forms of various sizes or passbooks.
All documents are fed by the document printer over a flat bed according to the
principle of single- sheet processing, are processed and ejected again. The processing of a document is begun when each single document is put forward.
The form feed of the documents can be freely selected. The feeding of the documents is supported by an automatic alignment. The print characters can be positioned relative to all the document edges.
The following provides a comprehensive list of the characteristics of the document printing point:
– 90 printing points with 10 characters/ inch
– Automatic document alignment
– Automatic print head adjustment
– Automatic document edge detection
– Print head with 24 needles
– 2 print modes (LQ, Draft)
– ’24- bit’ and ’8- bit’ graphics
– The print rate is dependent on the horizontal density of the character font
selected in each case. There are two different print rates for the print modes
LQ (Letter Quality) and Draft. The document printer can also process type
fonts, print qualities or multi- phase characters, which vary from the pixel
data structure of the standard character sets. More than two print rates are
possible due to the respective character font.
T5023/5023+ - Programming Guide 7
Options Short description of the document printer
Options
Magnetic stripe reader (MSR)
As an option, the document printer can be delivered with a magnetic stripe reader (MSR device) for passbooks. This enables reading and updating from the
magnetic stripe on passbooks depending on certain recording modes (DIN /
IBM). It is possible to changebetween various recording modes via the program.
MICR
Magnetic ink character reader for the fonts CMC7 and E13B.
Feeder
Single sheet feeder for 500 sheets A4.
Memory extension
The memory extension is necessary e.g. for journal data or asiatic fonts.

Programming interface (General)
This chapter contains general information on how the functions of the document
printer can be activated by a user program, i. e., how the document printer can
beprogrammed. This chapter also explainsthe functionswhich can be activated
by means of the program in a short, comprehensive summary.
Encryptions/Codes
The print functions of the document printer are initiated from aprogram in which
uniquenumeric encryptions (codes)representing charactersand commandsare
transmitted from the computer to the printer. The individual codes stand for printable characters (letters, numbers, punctuation marks, mathematical symbols)
or control codes, which cause certain actions (for example, document ejection,
deletion of characters, carriage return).
T5023/5023+ - Programming Guide 13
Encryptions/Codes Programming interface (General)
ASCII code
A code table specifies how the printable characters and control commands, for
example, for document ejection and carriage return are encrypted binarily in the
computer or printer. The encryption is expressed by a corresponding hexadecimal or decimal number. A certain character then lies in hexadecimalnotation or
in the decimal representation, for example, in the range hex 00 to hex FF or decimal 0 to decimal 255 (8- bit encryption).
Examples:
Character Meaning Decimal Hex
A
a
4
LF
ESC
With the document printer and with most computers the basis for the encryptions is
the code system ASCII ( A merican S tandard C ode for I nformation I nterchange),
which only differs in certain characters for special foreign languages (national ASCII
table). The ASCII code is encrypted via 7 bits, whereby 128 different meanings are
possible

Escape sequences / CSI sequences
As the ASCII table provides fewer control codes than print functions, the commands
for the printer normally consist of a sequenceof two or more ASCII characters. Such
a code sequence is always preceded by the encryption of the control code ESC (Escape) (ASCII code 27 (decimal) or 1B (hexadecimal). This signals to the printer that
the encryptions following ESC are to be interpreted as commands for
the printer.
There are two kinds of code sequences for the document printer:
– ESC ...
Code sequences, which begin with ESC or the appropriate encryption, are
called ESC sequences.
– CSI ... = ESC [ ...
Code sequences introduced with CSI (Control Sequence Introducer) are
called CSI sequences. CSI sequences are introduced with encryptions of
the character sequence “ESC [” and concluded with the encryption of two
14
T5023/5023+ - Programming Guide
Programming interface (General) Encryptions/Codes
characters depending on the command I (= Intermediate Character) and F
(= Final Character). The CSI sequences are used to control special document printer functions for document and MSR processing (see “document
printer specifications” in this chapter and the chapter “Additional commands”).
Examples (ESC sequences):

Activating the document printer functions
Thecontrolcodes or ESC or CSI sequences must beaddressedtothe printer directly
and uniquely via corresponding program commands. Depending on the respective
programming language, this is, e. g., via PRINT or WRITE instructions.
Example:
Three lines are to be printed. Lines 1 and 3 are printed in normal print, line 2 in
italic print.
Pseudo code:
BEGIN
PRINTLF(" first line")
PRINT(ESC 4)
PRINTLF(" second line")
PRINT(ESC 5)
PRINTLF(" third line")
END
Conversion into BASIC
10 LPRINT "first line"
20 LPRINT CHR$(27);" 4";
30 LPRINT "second line"
40 LPRINT CHR$(27);" 5";
50 LPRINT "third line"
Result:
In this manual the program examples are depicted exclusively in the
form of a pseudo code and the control codes or code series are given
in decimal ASCII encryption or directly as characters. The corresponding information must then be converted into the appropriate programming language.

Print effects
The design of a print product is dependent on the print quality, type font, type
size or character width and highlighting text, e. g., by underlining or bold print.
Print quality
Theprint quality is characterized bythe density of the print characters and bythe
print rate. The document printer provides two print qualities:
– LQ mode (Letter Quality)
The LQ mode has the higher print quality and lower print rate.
– DQ mode (Draft Quality)
The DQ mode has a lower print quality, but a higher print rate.
Example:
The print quality can be selected by means of the corresponding ESC sequences via a program or the menu.

Fonts
In addition to the DQ font for drafts, the default fonts Roman, Sans Serif, OCR A
(OCR A1 Eurobanking) and OCR B (OCR B1 Eurobanking), as well as the character set ISO 8859 with the following versions are available for Letter Quality
(LQ mode):
– East Europe
– Cyrillic
–Greece
–Hebrew
–Turkey
The DQ, Roman and Sans Serif fonts are selected via corresponding ESC sequences in the program.
The OCR- A, OCR- B and ISO 8859 fonts, as well as all special, non- Epsoncompatible fonts, can only be selected via CSI sequences. The character fonts
thus selected are treated like normal LQ type fonts, this means that all standard
commands (print quality, character size, print type) are also effective for these
fonts.

Font size / character density
The width of a printed character is expressed in ’characters per inch’ (cpi) and is
often called ’character density’, for example
10 characters per inch = 10 cpi
The document printer can print in the character widths 10, 12 and 15 pitch. Each
individual character is then the same width.
Example:
The font size can also be influenced by proportional type, as well as by elongated or condensed print.
Proportional type
With proportional type each character takes up a different amount of space accordingto its size(for example, ’I’takes up lessspace than ’B’or ’t’ lessthan ’g’).
Texts in proportional type are normally shorter than in normal print.
Example:
Elongated print
With elongated print, each character is represented in double width. It is possible, for example, to highlight page headings in a text.

Condensed print
If printing takes place in 10 or 12 pitch in condensed print, each character can
be reduced to 60% of its width in normal print.
