HP-UX 11i v3 International Printing Features

Some of the built-in options are, in fact, aliases of PPD options listed in the following table. Therefore,

specifying the corresponding PPD options is equivalent to using the built-in options.

Text Printing Notes

Most European mono-spacing fonts, such as Courier, have glyphs with a width-to-height aspect ratio

of about 0.6. Most CJK fonts containing ideographic characters have glyphs shaped like a square

with an aspect ratio of 1. As an ideographic character is expected to have the same width as two

ASCII characters, those ASCII characters must have an aspect ratio of 0.5. That is why ASCII

characters printed in an Asian locale sometimes look taller and narrower than ASCII characters

printed in the C or other European locales. Many CJK fonts also contain half-width ASCII characters

with an aspect ratio of 0.5 and are adjusted for a better match with the corresponding ideographic

characters.

When printing Unicode files, the psfontpf print filter determines whether any full-width characters,

like a CJK ideographic character, appear in the text file. If the file contains no full-width characters,

the other characters are printed with the natural aspect ratio of 0.6, unless this ratio is overridden by

the use of another font containing narrow characters with a 0.5 aspect ratio. When the file contains

some full-width characters, the half-width ASCII characters are printed with an aspect ratio of 0.5.

By default, the Courier font in the printer is used to print ASCII characters. To make the ASCII

characters look better when mixed with full-width ideographic characters, you might need to substitute

(download) the glyphs of the half-width ASCII characters in the CJK fonts, as you would with the

ideographic character. This can be done if the psfontpf configuration file defines 12 as the value

of the latin1 font type entry.

In portrait mode, letter-size paper holds 60 lines of 80-column text, whereas A4-size paper holds 66

lines of 80-column text by default. In landscape mode, the default is 45 132-column lines for both

paper sizes. For other paper sizes, the psfontpf print filter defaults to the use of 11-point fonts with

number of lines per page and characters per line determined by the current page size and page

margins.

You can change these default values by explicitly specifying the following groups of options, in

descending order of priority:

• hmi, vmi

• cpi, lpi

• width, lines/length

These options are interrelated, and changing one might force the others to change. For example:

lines-per-inch = lines/(page-height – top-margin – bottom-margin)

In such cases, an option you specify at a later time might invalidate a previously specified, related

option. For example, a letter-size page (8.5 inches x 11inches) with a page margin of 0.5 in and 6

lines per inch typically prints 60 lines per page. If you specify 66 as the number of lines per page

(lines) forces the lines-per-inch value to become 6.6.
