Managing font metrics for a rendering device

摘要

A system for printing a document that includes one or more target fonts that are emulated with at least one substitute font in a manner that preserves the original pagination and line breaks of the document. A table is provided that lists strategies/logic for enabling the printing device to emulate each of a plurality of predetermined target fonts with a substitute font. These emulation strategies may include but are not limited to, identifying at least one of a resident font for the printing device, stretchable font, local font, downloadable font, font data provided by a 3rd party, or font data that is embedded in a received document. Target font metrics may be employed as “hints” to refine emulation information for the target font data.

1. A method for enabling a mobile hardware device to print a document at a hardware printing device, comprising:
receiving the document at the mobile hardware device, wherein the document includes text and identifies at least one target font reference for each character of the text; when the target font reference is unlisted in a font strategy table and the document includes at least one embedded target font, embedding the at least one target font data in the document, wherein the embedded target font data is employed to update the font strategy table with at least one new entry; when the target font reference is unlisted in the font strategy table and the at least one target font data is available from a 3rd party, downloading the at least one target font data from the 3rd party, wherein the downloaded target font data is employed to update the font strategy table with at least one new entry; when the target font reference is listed in the font strategy table, employing a corresponding entry in the font strategy table to identify target font emulation information that includes a substitute font that the hardware printing device is capable of printing; employing at least one metric of the target font reference to improve an accuracy of the target font emulation information, wherein the improved emulation information is provided to the hardware printing device; and providing the document and emulation information to the hardware printing device, wherein the printing device employs the provided emulation information to print each character of text included in the document.
