hp euro SIMM (C4211A)

Introduction

Hewlett-Packard has made available the Euro SIMM (C4211A) hardware solution for use with the LaserJet 5, LaserJet 6P, LaserJet 5Si and LaserJet 5Si Mopier printers. When installed into the appropriate LaserJet printer, the Euro SIMM hardware integrates the Euro character into the printer as a device font. In other words, the Euro SIMM makes the Euro character available for your application's use in the same manner that the printer makes characters from its original, on-board fonts available. It is the intent of this primer to provide you with appropriate font selection and metric information so you can access the Euro and position it on the page as required.

Table 3 below lists the symbol sets, supplied by the Euro SIMM, which contain the Euro character. It is important to note that in order to print the Euro, the unbound typefaces on the Euro SIMM must be used in conjunction with one of the symbol sets that contain the Euro character. The unbound typefaces listed in Tables 1 and 2 can easily be identified by the underscore ( __ ) in their Symbol Set value field. This character indicates that you can fill in this field with any valid symbol set value. Remember, only those symbol sets listed in Table 3 contain the Euro character.

This section provides the metric information for the Euro character. Table 4 below depicts each typeface and the Euro width value. The width value, expressed as HorzEsc, is taken either from the TrueType, Intellifont or Bitmap font directly. Each value represents the width of the Euro relative to the TrueType design window, the Intellifont design window or the Bitmap font resolution, respectively. You can find information for converting these data into PCL Units of Measure immediately following Table 4.

In order to convert TrueType metric information into PCL Units of Measure, you must first determine whether the typeface used requires single or double  rounding calculations, and then use the appropriate formula. You will find that each typeface is listed in the appropriate rounding secton.

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 4 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:

Albertus ExtraBold

11 point at 600 dpi, 300 uom

Assume the following values:

b = 1 inch/72 points

c = 11 points

d = 1360 Design Units

e = 2048 Design Units

dpi = 600 dots per inch

uom = 300 PCL Units of Measure

EMsize = 11 * 1/72 * 600

= 91.66 dots

= 92 dots

x = round(1360/2048 * 91.66 * 300/600)

= round(30.433)

= 30 PCL Units of Measure

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

Here is 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 = 1139 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(1139/2048 * 92 * 300/600)

= round(25.583)

= 26 PCL Units of Measure

In the case of the LinePrinter typeface, the metric data is resolution specific. The resolution of the LinePrinter supplied by HP Euro DIMM is 300 dpi. As such, the metric data describes the width of the Euro in 1/300-inch increments. To convert this value inches, simply divide it by 300.
