  • Page 108: Chapter 9 Download Characters

    hapter 9 DOWNLOAD CHARACTERS With this printer you can create new characters and symbols, download their dot data, and have them printed in place of selected characters in the regular character set. Characters that can be generated in this way range from simple but useful symbols like the check mark through to complex Chinese or Japanese characters.

  • Page 109: Assigning The Character Data

    Photocopy the grid in Figure 9-1 to help design your new characters. We will use a tiny representation of a telephone symbol for our example. Figure 9-1. Use this grid (or one similar to it) to define your own characters. Assigning the character data Now, we calculate the vertical numerical values of the columns of dots, and enter them underneath the grid.

  • Page 110: Assigning A Value Of Character Space

    Assigning a value of character space Besides being able to specify the actual width of the character, this printer allows you to specify the position in the standard grid where the character will print. You must specify the dot column in which the printed character starts and the dot column in which the character ends.

  • Page 113: Defining Your Own Characters With Ibm Mode

    DEFINING YOUR OWN CHARACTERS WITH IBM MODE Downloading fonts in IBM mode requires downloading character Dot Pattern data and character Index Table data. Dot pattern data controls which pins fire when printing a character. Index Table data is placed in a “lookup table” that provides information on where Dot Pattern data is stored in memory and defines certain attributes of the character.

  • Page 114: Assigning The Character Dot Pattern

    Assigning the character dot pattern We will use a tiny representation of a telephone symbol for our example. Figure 9-3. Telephone symbol with LQ pica. After you have designed the character pattern, you need to compress the Dot Pattern. Data compression allows you to store more download characters than without compression.

  • Page 115: Assigning The Index Table Data

    After you have written the compression mask bit data, line up all the character data for the compression mask bit that requires “0”. The telephone symbol looks like Figure 9-5. Figure 9-5. Compressed character pattern of telephone symbol. Now we calculate the vertical numerical values of the columns of dots, and enter them underneath the grid.
  • Page 116 The third byte, m3, indicates the character type and the dot pattern data width in the mamory. If the character is normal, simply enter the width of the dot pattern in the memory. If your character is block graphics, add 128 to the width of the dot pattern in the memory.

    hapter 10 MS-DOS AND YOUR PRINTER When using your printer with an IBM PS/2, PC-AT or compatible, you will probably be using PC-DOS or MS-DOS as the operating system. A number of software tricks may be useful here. This chapter is not, however, a substitute for the operating system manuals supplied with your computer.
  • Page 121 See your DOS manual for further information about the PRINT command. If your system does not include PRINT.COM, you can print files by using the PRN device name in COPY or TYPE commands such as the following: COPY and TYPE do not permit you to execute other commands while the file is printing.
  • Page 122 ^V indicates that the following character is a control code. ^V[ enters the <ESC> code <ESC> has character code 27, and “[” is the 27th character from A in the ASCII sequence. Similarly, ^VA enters the control code <1>. See your DOS manual if you need further information about EDLIN. You can now set up the printer by sending it the file LQELITE.DAT.

  • Page 123: Programming With Basic

    PROGRAMMING WITH BASIC As an example of programming the printer on Microsoft BASIC, we have listed the program for the IBM-PC. This program runs in the downloadable condition.
  • Page 129 How the program works This program begins by assigning a number of printer commands to BASIC string variables (lines 1000 to 1060). You can find most of these commands near the beginning of chapter 8. The WIDTH “LPT1:” 255 statement in line 1080 means infinite line width. It prevents the IBM-PC from inserting unwanted carriage returns and line feeds in graphics data.
