hp eurosign fonts

Introduction

HP has produced two styles of Euro soft fonts, EuroSign and EuroSign Mono. Eurosign is a proportionally spaced typeface, while Eurosign Mono is a fixed-spaced or mono width typeface. These fonts contain only two characters - the space character and the Euro character. The design has allowed us to provide these fonts to you free of licensing, and we encourage you to use them in your applications that require a soft font solution.

It is the intent of this document, along with the accompanying sample files, to provide you with the information you need to implement the HP EuroSign Fonts.

The HP EuroSign Fonts have been designed to work with all of the LaserJet printers that can accept soft fonts. This has been achieved by including a variety of soft font formats. To be specific, the HP EuroSign Fonts come in the following formats, TrueType, PCLeTTo, Bitmapped and PostScript Type 1 scalable.

Table 1 below provides a mapping between the HP Euro font files, their associated font format and pertinent charactersitics. Before you integrate any of these fonts into your application, make sure the targeted LaserJet printers can accept the font formats you choose!

This section provides the metric information for the Euro character. Table 5 below depicts each typeface and the Euro width value. The width value, expressed as HorzEsc, is taken either from the Bitmap or TrueType font directly. As a result, each value represents the width of the Euro relative to the Bitmap font resolution or the TrueType design window, respectively. You can find information for converting these data into PCL Units of Measure immediately following Table 5.

In the case of bitmap typefaces, the metric data is resolution specific. The metric data describes the width of the Euro in either 1/300- or 1/600-inch increments. To convert this value inches, simply divide it by the appropriate resolution.

The following examples convert 300 and a 600 dpi, bitmap font metric data into inches:

eu300m10.sfp

30

----- = .10 inches per character

300

eu600p12.sfp

73

----- = .12167 inches per character

600

In order to convert TrueType font metrics into PCL Units of Measure, you must use the following formula:

EMsize = round(c * b * dpi)

x = round(d/e * EMsize * uom/dpi)

Where:

EMsize = size of EM in device resolution dots

c = point size of font

b = inches per point

dpi = device resolution

x = desired metric value in units of measure

d = metric value in Design Units (HorzExt)

e = number of Design Units in the design EM

uom = PCL Units of Measure

As you can see, most of the values for these variables are supplied by your application, and depend upon the font selection criteria at print time. The exceptions are 'd' and 'e'. Table 5 supplies the value for the variable 'd', while 'e' is the constant value 2048.

Here's an example usage of the TrueType metric conversion formula supplied above.

TrueType Method:

Arial

11 point at 600 dpi, 300 uom

Assume the following values:

b = 1 inch/72 points

c = 11 points

d = 1485 Design Units

e = 2048 Design Units

dpi = 600 dots per inch

uom = 300 PCL Units of Measure

EMsize = round(11 * 1/72 * 600)

= round(91.66)

= 92 dots

x = round(1485/2048 * 92 * 300/600)

= round(33.354)

= 33 PCL Units of Measure

We have provided some sample print jobs to help demonstrate the usage of the HP EuroSign Fonts. Table 6 provides a description of each sample. Each sample contains the font data as well as page data that selects and positions the Euro. Please feel free to use these files to aid your understanding of Euro implementation using HP's EuroSign Fonts.
