Appendix C. Host Attachment
• The IBM Coax/Twinax feature will not support P–series or EVFU
control codes coming from the host. The IBM Coax/Twinax feature may
not be compatible with some older applications running on an installed
Printronix printer. In that case, the Multi–Platform Interface
Coax/Twinax feature should be installed.
• The coaxial portion of the IBM Coax/Twinax feature of this printer is
subject to the following limitations:
Minimum dot matrix of 9 wide by 8 high
Minimum dot matrix of 4 or 7 wide by 8 high
NOTE: The following features are not supported:
IBM 3287 Models 1C and 2C
Programmed symbols 2 and 4, 190 character downloadable fonts
Data analysis = APL feature
Graphic escape
• The twinaxial portion of the IBM Coax/Twinax feature of this printer is
subject to the following limitations:
Minimum dot matrix of 9 wide by 8 high
Minimum dot matrix of 4 or 7 wide by 8 high
Print lines greater than 198 characters
• IBM 6400 vs 4234 IPDS Comparisons –– 4234 Emulation Differences
The 4234 emulation will not support Load Symbol Sets (LSS)
The 4234 emulation will use Courier for all Near Letter Quality
(NLQ) mode printing, whereas 4234 NLQ mode was Gothic for
13.3, 16.7 and 18 CPI.
The dot sizes are different. Also, the 6400 has a single dot size vs
three with the 4234. For bar code applications, some combinations of
unit module width, wide–to–narrow ratio, and element height may
affect read rates.
The 4234 emulation will support image and font resolution of 120 x
144 pel, compared to 144 x 144 pel in the 4234. This will cause
images to change size in the vertical dimension.
• Proportional Space Mode (PSM) is not the same. Some differences will
occur.
