Overview

HP Roman is a family of

thermal printers since 1986.[7] The latest off-spring of the family is HP Roman-9, which was introduced in 1999 to include the euro sign.[8] PCL Ventura International
is based on HP Roman-8.

Character set

Roman Extension

The character set was originally introduced by Hewlett-Packard as extended ASCII 7-bit codepage named HP Roman Extension,[9][10] which existed at least since 1978.[11][12][13][14][15] This character set was used as a secondary character set in conjunction with the primary character set, which was identical to ASCII, except for character 127, which was a medium shaded box instead of the delete character. The first 32 characters, that normally functioned as C0 control codes, also had graphical non-control alternatives, that could appear during self-test or display functions mode. Switching between character sets was done using the Shift Out and Shift In characters, or alternatively, on systems supporting 8-bit mode, using the high bit of the character. Before the name "Roman-8" was established for the 8-bit variant in 1983, this was sometimes called "8-bit Roman Extension" or "HP Roman-8 Extension". Over the years both variants were revised to include more characters. The final 1985 revision of the secondary character set was also standardized by IBM in 1989 as code page 1050 (CP1050 or ibm-1050).[16]

Although strictly speaking not part of Roman Extension, the following table shows those rows of the primary character set that differed from ASCII. Note that the first two rows are normally the same and only appear as graphical characters in special circumstances, as described above. Although some of the Unicode control pictures conventionally use three characters rather than two, those "diagonal lettering glyphs are only exemplary; alternate representations may be, and often are used in the visible display of control codes".[17]

    £ and whether this character has a single or double bar is merely considered a typographical variation of the same character. U+20A4 ₤ exists solely for compatibility with this character set, HP Roman-8, in which the singly barred glyph is coded as BB16 and the doubly barred glyph as AF16.[18]

Roman-8

HP Roman-8 is an 8-bit

single byte character encoding that is mainly used on HP-UX[2] and many Hewlett-Packard[7] and PCL compatible printers. The name Roman-8 appeared in 1983,[1] but a precursor of the character set was already used by the HP 250 and HP 300 workstations since 1978/1979 as 8-bit Roman Extension.[12][13][14][15]

The original 1983/1984 version of Roman-8 still had some code points undefined.

ð).[4][20][21] This final revision of the character set was also standardized as codepage 1051 by IBM in 1989.[22][23]

In contrast to the newer HP Roman-9, HP Roman-8 does not provide a code point for the euro sign.

The following table shows the latest 1985 definition of the HP Roman-8 character set (with some remarks regarding former definitions and alternative interpretations). Each character is shown with a potential Unicode equivalent and its decimal code, however, sources differ in the recommended translations for some of the codes even among definitions from Hewlett-Packard[2][21] and IBM.[22][23]

    This file has remained essentially unchanged since it was imported from cdctables.zip in 1995; only a few flags have been changed:
    In July 2000 some characters were marked as mapping only from Unicode, but not back:

    Fullwidth ■ \xFC # SM470000 → Fullwidth ■ \xFC # SM470000 |1
    These are all cases where multiple characters map to the same byte.
    In November 2000 some characters were marked as mapping only to Unicode, but not back:
    - \xF6 |0 → - \xF6 |3
    ` \xA9 |1 → ` \xA9 |3
