The IBM 4226 Model 302 is a heavy-duty, unattended, serial dot matrix printer with speeds up to 533
characters/second (CPS). It is program compatible with the IBM 4202-003 Proprinter* IIIXL and the Epson** DFX-5000 printers. The 4226 fills a customer need for a low cost, high-speed, heavy-duty,
unattended, impact, continuous-form (up to six-part) printer that is attachable to the PS/2 and other IBM systems with an ASCII interface. Program compatibility with the IBM 4202-003 and Epson
DFX-5000 protects the customer's software investment.
Highlights
533 CPS maximum draft speed
Unattended operation
IBM PPDS (Personal Printer Data Stream) and Epson DFX-5000 Emulation
Heavy-duty entry printer (multipart forms, up to six-part)
EIA-232/EIA-422 and Parallel Attachments are Standard
"Clean Hands" 15 Million Character Yield Ribbon
22 Kb Receive Buffer is standard
User Productivity
The IBM 4226 Model 302 Printer provides the user with unattended continuous-form printing capability.
The automatic emulation switching (via SIC Code Commands) eliminates the need for operator intervention between jobs sent to the printer. The user-friendly operator panel is designed for the
operator/user having limited printer knowledge. The IBM 4226 Printer provides a demonstration that is easy to invoke and produces a printed page without system attachment.
Systems Management
The IBM 4226 Model 302 Printer can attach to IBM PS/2 and non-IBM PC compatible systems via a
parallel attachment. In addition, further flexibility has been provided with connectivity through the ASCII LPTX and COMX ports to the following system environments: AS/400, RISC System/6000, and System/370.
The 4226 IBM Model 302 Printer offers an ASCII version only.

Technical Description
The 4226 Printer is offered in one model, the 4226-302. The 4226-302 Printer is (533/400/100 CPS) 9
Wire Serial Dot Matrix Heavy Duty Entry System Printer. Average use is 120 million characters per year and maximum use is 144 million characters per year. The 4226-302 Printer offers multiple quality
levels of printing: Fast Draft, Draft, NLQ, and Raster Graphics. Character design for the multiple qualities are based on the same matrix as IBM 4202 models. The print quality of each level is equal to
or better than that achieved with the IBM 4224 and Epson DFX-5000 printers. The 4226-302 Resident Fonts and Character Spacings available in the printer when set in the "Proprinter Mode" are listed below:
10 CPI (Fast Draft, Draft, Gothic, Courier)
12 CPI (Fast Draft, Draft, Gothic, Courier)
15 CPI (Draft)
17.1 CPI (Draft)
20 CPI (Draft)
Proportional Spacing (Draft, Gothic)
The following list shows the various Resident Fonts and Character Spacings available in the 4226-302 Printer when set in the "Epson Emulation mode":
10 CPI (Fast Draft, Draft, Gothic, Courier)
12 CPI (Draft, Gothic, Courier)
15 CPI (Draft)
17.1 CPI (Draft)
20 CPI (Draft)
Proportional Spacing (Draft, Gothic, Courier)
The burst speed for the 4226-302 is 533 CPS in Fast draft Mode, 400 CPS in Draft Mode and not less
than 100 CPS in NLQ Mode. Line spacing of six or eight Lines Per Inch (LPI) or increments of 1/144-inch. Several modes of print emphasis are provided: Emphasized (Bold), Double Wide, Double
High, Double Strike, Underscore, Overscore, and Super/Subscripts.
There is a resident on board demo in the 4226-302 Printer which consists of a two page (only US
Version) print demo (stored in ROS) and is easily accessible through the operator panel. This demo is available to the marketing personnel to assist them in explaining the 4226-302 Printer's features and to
the customer and the CE for verifying printer functions during Customer Setup and servicing.
The 4226-302 user is not required to adjust their continuous forms, press buttons, or in any way oversee
the operation of the printer once it has been properly setup to run a print job and the printer has started printing. The 4226-302 Printer will complete multiple jobs without intervention (even switching
automatically between IBM and Epson emulation modes) provided there are sufficient continuous forms available to complete the tasks being sent to the printer.

Three to six Part Forms: 45 to 56 g/sq m (12 lb to 15 lb)
Carbon Paper weight: 30 g/sq m (8 lb or less)
Fastening limitation: Spot glue multi-part forms and crimped forms must meet the following specifications:
Gluing On Multi-part: Spot gluing. The gluing should be even on both right and left edges without significant
crumples.
Crimped Form must be fixed on both sides. Crimping must be in the direction of paper motion. The crimp of the
first-part paper must extend behind the last part paper.
Metal or tape fasteners along the edges are not supported.
Feed holes must be free of chads and crimps to avoid real/false paper jams.
Paper hole or cut is not supported in any printable area.
Perforation Strength - Strong enough for normal operation.
The tent at fold perforation is less than 1 mm high.
Notes:
Form length exceeding 11 inches may not stack correctly.
Forms less than 6 inches in length or width should be tried for satisfactory stacking and may require operator assistance.
Cut Sheet paper is not supported (Continuous Form Paper Only, up to 6 part).
Additional Attachment Information
A parallel interface cable is required for standard attachment of the 4226 Model 302 Printer and must be
ordered separately. If Serial Connection is required, the appropriate EIA-232 Serial Attach Cable P/N 6486685 must be used.
