Introduction Your IBM 4230 Printer is a wire-matrix printer with many features to help you perform your work efficiently. Your printer combines excellent print quality along with the ability to print in several print styles and graphics. Your printer receives some instructions from you and some instructions from the computer system. The computer does the processing; the printer prints the result. It is important that you communicate with the people who operate and program the computer so that you know when any changes are made that could affect your printer. The 4230 Printer can use one of four different forms devices to move paper through the printer. Each device does a different type of print job, depending on the type of forms you use: continuous forms for large printouts, tear-off forms such as retail invoices, or cut sheet forms. See "Forms Handling Devices" on page 3-19 for more information. The 4230 Printer has four different print quality settings: Fast Draft Quality DP (Data Processing) Quality DP Text Quality Near Letter Quality. You can set the character spacing on the 4230 Printer to the following characters per inch (CPI): 10 12 15 16.7 (Fast Draft and DP Quality only) 17.1 (Fast Draft and DP Quality only for Models 4S3 and 5S3 when parallel or serial is the active interface) 20 (Fast Draft and DP Quality only for Models 4S3 and 5S3 when parallel or serial is the active interface) Preface xix
