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 4I3 and 5I3
when parallel or serial is the active interface)
20 (Fast Draft and DP Quality only for Models 4I3 and 5I3 when
parallel or serial is the active interface)
