They are listed in order by decreasing compatibility as you go down the list: select one from as high up on the list as possible, based on what is available from among the drivers supplied with your software.

  • Page 41: Okidata Software Drivers

    Don’t be surprised if boldfaced items are printed twice, underlines are misplaced, wide spaces are left between lines or the printer behaves chaotically (turn off the printer if the latter occurs). These are all characteristics of an incompatible driver selection.

  • Page 43: Software Driver Selection

    Embedded Commands In some cases, commercial software packages will permit you to create and/or modify the printer driver. Even if a driver specifically designed for the printer is available, this option can provide additional room for customization. Typically, the driver modification routine will present a list of operations with some method for entering printer commands, permitting substitution, such as entering the italic command in place of the underline command.

  • Page 85: Custom Character Commands: 24-Pin Printers

    Utility Proportional Note: If the printer is in superscript or subscript mode, only the first two or last two bytes are needed for each column. Characters are designed on a grid made up of columns of 24 dots. Each column, in turn, is divided into three 8-dot groups, and each 8-dot group is represented by a byte of data.

  • Page 86: Ibm Custom Character Commands For 24-Pin Printers

    Your arrangement of dots is translated into code that tells the printer the exact locations of each dot in each column. The example below shows how this works. Byte 1 Byte 2 Byte 3 The width of the grid in dots depends on the printing mode in use. This example character is 27 dots wide and has 4 blank columns on either side.
