Section Section 6: Using the Printer Interface 91 6 Using the Printer Interface The printer interface is the physical connection point between the printer and other devices, such as a computer. The 2400 series printer offers a choice of three printer interfaces: parallel, Universal Serial Bus (USB), or serial.
Section 6: Using the Printer Interface 92 Computer to Printer Communication The parallel interface transfers data from computer to printer. The data path is 8 bits wide. The printer and the computer synchronize data transfer with the interface signals STROBE*, ACKNLG*, and BUSY.
93 Section 6: Using the Printer Interface Pin Connections The following illustration shows the pin assignments for connecting the 25-pin connector to the 36-pin connector.
Section 6: Using the Printer Interface 94 Parallel Pin Assignments Pin Line Description 1 STROBE* When the printer receives the STROBE* low from the computer , the printer reads the data from the interface and sets the BUSY line high. STROBE* must not occur when the BUSY line is high; otherwise, unpredictable r esults may occur .
95 Section 6: Using the Printer Interface Timing The following chart shows the timing in microseconds of these signals. 31 INIT* INIT* from the system r esets the printer to its initial power- on-state. The BUSY line goes high, and any received data is printed.
Section 6: Using the Printer Interface 96 Universal Serial Bus Interface The USB interface, with a signaling bit rate of 12 Mb/s (full speed), is in full compliance with the Universal Serial Bus Specification Revision 1.
97 Section 6: Using the Printer Interface Serial Cable Pin Assignments (RS-232C) The following illustration shows the RS-232C serial cable: RS-232C Serial Connector Pin Assignments Pin Signal Description 2 TXD (T ransmit Data) This line transmits data fr om the printer to the host.
Section 6: Using the Printer Interface 98 Serial Interface Cable (RS-232C) The recommended RS-232C serial cable is 50 feet long. This cable works with the IBM PS/2 series and other compatible host systems using a 25-pin male connector.
99 Section 6: Using the Printer Interface Using an IBM AT Personal Computer (RS-232C) If you are using an IBM AT or compatible computer, use a 9-pin to 25-pin EIA RS-232C cable. We recommend one of the following for a 9-pin to 25-pin cable: • IBM P/N 6450242 (254 mm or 10 in.
Section 6: Using the Printer Interface 100 The voltage reference point is the signal ground on pin 7. A timing or control line is active if the voltage is more than +3 V, or inactive if the voltage is less than -3 V. A data signal more than +3 V means that the bit is a logical 0; less than -3 V means that the bit is a logical 1.
101 Section 6: Using the Printer Interface When No parity is selected, the pritner expects no parity bit when it receives data. The printer transmits data without parity bits. When Ignore parity is selected, the printer expects a parity bit when it receives a data frame.
Section 6: Using the Printer Interface 102 The following diagram illustrates DTR Protocol Timing. Legend: 1 The R TS signal is driven dir ectly by the RS-232C line driver and is active any time power is supplied to the printer .
103 Section 6: Using the Printer Interface 2 Because all data transmissions require CTS, it must be detected prior to the XON/XOFF protocol initiating. Once CTS is detected, after POR, the printer transmits an XON command. It is not necessary for the host to detect this initial XON command prior to transmitting data to the printer.
Section 6: Using the Printer Interface 104 1 Select the printer icon. 2 Select Open . 3 Select Settings . The Printer - Settings scr een appears. 4 Select the serial port to which you want to attach the print er. The Serial Port - Settings sc reen appears.
Section Section 7: Downloading Char acters and F onts 105 7 Do wnloading Character s and Fonts This chapter explains how to download characters and provides programming examples for several escape sequences. The first part of the chapter is for 248x users; the second part is for 249x users.
Section 7: Downloading Char acters and F onts 106 Vertical Lines The following drawing shows how the printer adds dots to a vertical line. The solid dots must be specified in the font. Hollow dots are generated by the printer. Diagonal Lines These drawings show how the printer adds dots to diagonal lines.
107 Section 7: Downloading Char acters and F onts Intersections of Vertical and Horizontal Lines The drawing on the left shows how the printer adds the vertical dots to a vertical line that intersects a horizontal line. The character design must specify all dots in the horizontal line.
Section 7: Downloading Char acters and F onts 108 Diagonal Intersecting Horizontal Line This drawing shows how the printer adds dots at the intersection of horizontal and diagonal lines. The printer considers the point of intersection as a two-dot vertical line.
109 Section 7: Downloading Char acters and F onts When a diagonal line intersects a vertical line at a point other than the end of the vertical line, you should specify a horizontal dot at the intersection to improve character appearance. This ensures that the character is acceptable in Draft.
Section 7: Downloading Char acters and F onts 110 Initializing the Download Area Use the following command to initialize the download areas to the resident fonts: Downloading a Draft/NLQ Character Set The sequence to download characters for Draft/NLQ and Fast Draft is shown below: There are two parts of the ESC = escape sequence.
111 Section 7: Downloading Char acters and F onts Part Two: Specifying the Download Data Attribute byte 1 specifies the character type and additional information. Bit Bit V alues Functions 7 0 if the character is an ascender (a character using only the upper 8 wires of the print head).
Section 7: Downloading Char acters and F onts 112 Attribute byte 2 specifies proportional-spacing information. Bits 6-0 specify spacing information. Set these bits to 0 if proportional spacing is not desired. When you use proportional spacing with a downloaded font that has bits 6-0 set to 0, all 11 bytes of character data print.
113 Section 7: Downloading Char acters and F onts Designing and Downloading the Draft/NLQ Copyright (©) Symbol This example shows how the 11 bytes of printable data for the ’©’ symbol were determined. This example replaces the ’ @ ’ character with the Draft ’© ’ symbol.
Section 7: Downloading Char acters and F onts 114 The following example loads data for the copyright symbol into the printer. The data remains in the download storage area until you: • Set the power switch to Of f. • Overlay the data with download character data.
115 Section 7: Downloading Char acters and F onts Downloading an NLQ II Character Set The 248x printers can download two sets of NLQ II characters. The first set is initialized to a Courier-like font, and the second to a Courier italic-like font.
Section 7: Downloading Char acters and F onts 116 Part Two: Specifying the Download Data Each font character is made up of 48 bytes of data. There are 2 bytes of attribute data and 46 bytes of character data. This field of 48 bytes must be repeated for each character.
117 Section 7: Downloading Char acters and F onts Attribute byte 2 is not used when specifying NLQ II. Set it to zero. Bit Functions Printable Data (Columns 1 to 23) • Defines the column data for each character from left to right. • Column 24 is always blank; therefor e, only 23 columns can be defined.
Section 7: Downloading Char acters and F onts 118 When NLQ II font data is downloaded, it is compressed. By filling in-between adjacent horizontal dots, character compression by the printer is more efficient. When you want to print the ’©’ symbol: • Send ESC I x07 to the printer to select the download characters in NLQ II mode.
119 Section 7: Downloading Char acters and F onts To replace the ampersand (’&’) symbol, use the following example to download and print the copyright © symbol.

Because 1 dot-column equals 1/360 inch, 1 unit is equal to 6 dot-columns.
123 Section 7: Downloading Char acters and F onts Count Count is the number of bytes of data being downloaded starting with the font ID byte. The count is a 2-byte value downloaded as the low byte followed by the high byte. Font ID Byte The font ID byte is a 1-byte number that identifies the font.
Section 7: Downloading Char acters and F onts 124 The Lookup Table • ASCII character 255, xFF , cannot be defined. It is a mandatory space and is the same size as ASCII character 32, x20. • ASCII Character 0, x00, is the zero slash. Any character downloaded to 0, x00 r eplaces the zero.
125 Section 7: Downloading Char acters and F onts Note: The lookup tables copied using the ESC = 0 0 command point to the res- ident fonts with the current code page. After receiving an ESC = 0 0 com- mand, the download area appears empty. Any valid download com- mand activates the download access.
Section 7: Downloading Char acters and F onts 126 This example shows the design for the ampersand character (ASCII 38) from the All Characters chart. This character design does not have any occurrences where extra dots can be added, resulting in a column being identical to its predecessor.
127 Section 7: Downloading Char acters and F onts Creating the Character Data Each dot column is sent to the printer as three bytes of data. To get the values of this data, convert the binary values to hexadecimal values. The ampersand figure shows the hexadecimal value for each byte in each column of the character.

Section Section 8: Barcodes 147 8 Bar codes This section describes how to use your printer to generate barcodes. Barcode Function You can print barcodes on your printer in both IBM and Epson emulation modes.
Section 8: Barcodes 148 UPC-A and EAN-13 barcodes use a flag character for number system encoding and country code. Your printer provides the capability of printing the human readable form of this flag character either in the vertical center along the left side of the barcode, or under the barcode with the other human readable characters.
149 Section 8: Barcodes k is the barcode type. m is the module width. Module is a term defining the smallest unit of measurement within a barcode. The module width, m , is used to determine both bar and space widths. B is a space module. A is a bar module.
Section 8: Barcodes 150 An example of Code 39, with m = 0 and m = 1, follows: m = 0 (the human readable character is printed) m = 1 (the human readable character is not printed) s is the space width adjustment factor . This parameter affects only space modules.
151 Section 8: Barcodes v1, v2 define the bar height. Use the following steps to calculate the values of v1 and v2 : 1 Determine the approximate desir e d height (in inches) of the bar . 2 Let V = 2160 x (height in inches). Round V to the nearest whole number .
Section 8: Barcodes 152 b1: human readable character 0: Prints human readable character . 1: Does not print human readable character . b2: flag character position (for EAN-13 and UPC-A only) 0: Center 1: Under b3-b7: Not used An example of deriving the c parameter follows: 1 Check digit is to be printed by the printer .
153 Section 8: Barcodes Data is the actual data to be transferred into the barcode symbology . The data for the barcode data transfer command is a string of ASCII characters immediately following the n1, n2 count bytes.
Section 8: Barcodes 154 The European Article Numbering (EAN) barcode is the European version of the all-numeric, fixed length UPC symbology. k value: 178, xB2 m value: 0 to 4, x00 to x04 s value: -3 t.
155 Section 8: Barcodes Examples: V alid EAN-13 command: Since the b0 bit of the c parameter has a value of 0 (check digit by host/ software), there must be 13 data characters ( x0D ) specified in the Data Transfer Command .
Section 8: Barcodes 156 Invalid EAN-13 command: Since the b0 bit of the c parameter has a value of 01 (check digit by printer), there must be 12 data characters ( x0C ), not 13 ( x0D ), specified in the Data Transfer.
157 Section 8: Barcodes data character set: Examples: V alid EAN-8 command: Character Hex ’0’ x30 ’1’ x31 ’2’ x32 ’3’ x33 ’4’ x34 ’5’ x35 ’6’ x36 ’7’ x37 ’8’ x38 .
Section 8: Barcodes 158 Since the b0 bit of the c parameter has a value of 01 (check digit by printer), there must be 7 data characters ( x07 ) specified in the Data Transfer Command. Invalid EAN-8 command: The letter ’C ’ is not a valid data character for EAN-8; the numbers ’0’-’9’ are the only valid characters.
159 Section 8: Barcodes CODE 39 This barcode symbology uses both alphabetic and numeric characters. The printer will add a start/stop character, ’ * ’, to the barcode and human readable character automatically.
Section 8: Barcodes 160 data character set: Character Hex Character He x ’0’ x30 ’M’ x4D ’1’ x31 ’N’ x4E ’2’ x32 ’O’ x4F ’3’ x33 ’P’ x50 ’4’ x34 ’Q’ x51 ’5’.
161 Section 8: Barcodes Examples: V alid Code 39 command: <x 1B5B66 - barcode setup command prefix 0600 - setup data length (low byte first) - x0006, 6 B4 - barcode type = Code 39 04 - module width = 4 = 0.038 inches on 248x, 0.026 inches on 249x 03 - space width adjustment = 3 = 0.
Section 8: Barcodes 162 Invalid Code 39 command: The lowercase ’a ’ is not a valid data character for Code 39. <x 1B5B66 - barcode setup command prefix 0600 - setup data length (low byte first).
163 Section 8: Barcodes INTERLEA VED 2of5 Interleaved 2of5 is used to express all-numeric messages. Two bytes of data are encoded to form one barcode character. If the check digit generation flag is on (b0 = 1), the printer will add a ’0’ to the data string automatically.
Section 8: Barcodes 164 data character set: Examples: V alid Interleaved 2of5 command: Since the b0 bit of the c parameter has a value of 01 (check digit by printer), note the 0 character added to the barcode above.
165 Section 8: Barcodes Invalid Interleaved 2of5 command: Four characters are specified in the Data Transfer Command. The first three characters, "058 ", are in the character set for Interleaved 2of5. The fourth character,’ $ ’, is not valid for Interleaved 2of5.
Section 8: Barcodes 166 data character set: V alid UPC-A command: Character Hex ’0’ x30 ’1’ x31 ’2’ x32 ’3’ x33 ’4’ x34 ’5’ x35 ’6’ x36 ’7’ x37 ’8’ x38 ’9’ x39 .
167 Section 8: Barcodes Since the b0 bit of the c parameter has a value of 01 (check digit by printer), there must be 11 data characters ( x0B ) specified in the Data Transfer Command.
Section 8: Barcodes 168 POSTNET This all-numeric symbology is used to express U.S. Postal Service ZIP codes. k value: 185, xB9 m value: 0 to 4, x00 to x04 s value: ignor ed minimum v1, v2 values: ignored; POSTNET uses two dif ferent bar lengths only: a long bar and a short bar .
169 Section 8: Barcodes Examples: V alid POSTNET command: <x 1B5B66 - barcode setup command prefix 0600 - setup data length (low byte first) - x0006, 6 B9 - barcode type = POSTNET 00 - module width.
Section 8: Barcodes 170 Since the v1, v2 values for the bar length are ignored for POSTNET, 00 00 is an acceptable bar length specification . Invalid POSTNET command: The ’- ’ (dash) is an invalid character for POSTNET.
171 Section 8: Barcodes Code 128 Code 128 is a flexible symbology that uses numeric and certain alphabetic and symbolic characters. It provides three separate character sets and a method of shifting between character sets within the same barcode. The first byte of the data string defines the character set.
Section 8: Barcodes 172 data character sets: The character and corresponding hex code for each of these character sets are shown on the following pages.
173 Section 8: Barcodes data character set A : Character Hex Code Character Hex Code Character Hex Code Character Hex Code NUL x00 Space x20 ’@’ x40 FNC 3 x60 OH x01 ’!’ x21 ’A’ x41 FNC 2 .

175 Section 8: Barcodes data character set C : Character Hex Code Character Hex Code Character Hex Code Character Hex Code ’00’ x3030 ’32’ x3332 ’64’ x3634 ’96’ x3936 ’01’ x3031 .
Section 8: Barcodes 176 V alid Code 128 command: <x 1B5B66 - barcode setup command prefix 0600 - setup data length (low byte first) - x0006, 6 BA - barcode type = Code 128 00 - module width = default 00 - space width adjustment = default 0404 - height (low byte first) - x0404 = 0.
177 Section 8: Barcodes Invalid Code 128 command: The first byte of the data string defines the character set and must be either ’A’, ’B’ or ’C’.
Section 8: Barcodes 178 V alid Code 128 command using multiple character sets: <x 1B5B66 - barcode setup command prefix 0600 - setup data length (low byte first) - x0006, 6 BA - barcode type = Code 128 00 - module width = default 00 - space width adjustment = default 0404 - height (low byte first) - x0404 = 0.
179 Section 8: Barcodes Notes For Barcode Printing • Bar code printing is always performed unidirectionally (left-to-right). • The desir ed barcode will not print if the barcode print area exceeds the right mar gin of the printer .
Section 8: Barcodes 180 • The desired bar code may not print if invalid characters ar e specified in the data transfer command. Example: Since the desired bar code is POSTNET ( B9 ), the letter ’a’ is not a valid character . The numbers ’0’-’9’ are the only valid characters for POSTNET .
181 Section 8: Barcodes • The desired bar code may not print if the number of characters specified by n1 , n2 does not match the r equired number for the desir ed barcode type. Example: The desir ed barcode type is EAN-13 (B2 ). The check digit is generated by the host/softwar e (b0=0).
Section 8: Barcodes 182 • When the m parameter is set to 1 ( m = 1), the printer does not print the human readable character . Example: Although the c parameter has a value of x00 , which tells the printer to print the human readable characte r, the m parameter has a value of x01 , which causes the b1 bit value of the c parameter to be ignore d.
183 Section 8: Barcodes • Completing the barcode setup and data transfer commands is not enough to print the desired ba rcode. Before the barcode can be printed, the printer must receive suf f icient vertical movement commands (line feed, vertical tab, form feed, etc.
Section 8: Barcodes 184 Example: • Bar code data and other print data (for example, text data) are contr olled independently . It is necessary to pr ovide suf ficient horizontal space for the barcod.
185 Section 8: Barcodes In this example, suf ficient horizontal space is inserted to eliminate overlap: Example : <x1B5B66 0600 B4 00 00 3804 00> Barcode Print Sample: <x1B5B70 0300> 395 T.
