Compatibility And Limitations - IBM 6400 Setup Manual

Compatibility and Limitations

The following are some compatibility and limitation considerations you
should be familiar with before attaching this printer with your system.
Compatibility
The Proprinter III XL emulation is very similar to the datastream used by
the IBM 4202–003 Proprinter but contains more features. This protocol
enables this line matrix printer to closely emulate a moving–head serial
matrix printer but does not support downloaded fonts. In addition, NLQ
compresses to 17.1 CPI, not 20 CPI.
The Epson–FX emulation does not support downloaded characters or print
justification. In addition, near letter quality (NLQ) compresses to 17.1 CPI not
20 CPI.
For Printronix P–Series emulation, differences in supported fonts and control
codes may exist between the IBM 6400 and Printronix printers. Downloaded
character overlays and downloaded character sets are not supported. Detailed
information on supported fonts and control codes can be found in the 6400
ASCII Programmer's Reference Manual.
For Printronix P–Series XQ Variant, the IBM 6400 only prints condensed print
at 15 CPI, like the Printronix P600, but unlike the P300, which printed
condensed print at either 13.3 or 16.7 CPI.
Emulation differences may exist between the IBM 6400 with Epson FX 1050
emulation and the Printronix MVP 150B, which used the Epson MX emulation.
Application differences may exist between the IBM 6400 and the Printronix
MVP–150C printers due to additional print quality modes which the 6400 does
not support.
Printronix printers with an "L" in the model design indicate the printer has the
capability to print smaller dots. The IBM 6400 will print text–only applications
that were printed by L–Series printers. Applications requiring the printing of
anything other than text will not be supported.
DAVFU, DVFU, NVFU and CVFU Vertical Format Units, along with the
optional uses of the Serial Data Bit 8, are not supported.
Printronix P6XX0 models using older C1 controllers, which are primarily
installed in Europe, are not supported.
The following printers, which are similar to Printronix printers, are not
supported by the IBM 6400 printer: KPG Panda, TRILAx (Trilog Inc.) and
Gentry REVerse Paper Feed.
