-"Resolution" is a word that is used with little concern for its
+Le mot « résolution » est un mot qui s'emploie sans se soucier de ses multiples sens dans le domaine du matériel informatique. Le mot suggère une mesure de ce qu'un observateur (peut-être l'œil humain) peut distinguer ; pourtant, nous voyons régulièrement des publicités pour des imprimantes dont la résolution est de [[wpfr>Point_par_pouce|1200 dpi]] --- bien plus fine que ce que l'œil humain peut distinguer sans aide. Les publicités parlent ici de la précision avec laquelle l'imprimante peut placer des points sur l'image imprimée, ce qui affecte la finesse de la représentation des polices et la précision du placement des glyphes et autres marques sur la page.
-multiple meanings, in computer equipment marketing.  The word suggests
-a measure of what an observer (perhaps the human eye) can resolve; yet
-we regularly see advertisements for printers whose resolution is
-dpi&nbsp;&mdash; far finer than the unaided human eye can distinguish.  The
-advertisements are talking about the precision with which the printer
-can place spots on the printed image, which affects the fineness of
-the representation of fonts, and the accuracy of the placement of
-glyphs and other marks on the page.
-In fact, there are two sorts of "resolution" on the printed page
+En fait, il existe deux types de « résolution » sur la page imprimée que nous devons prendre en compte pour les besoins de <latex>\TeX</latex> ou <latex>\LaTeX</latex> :
-that we need to consider for (La)TeX's purposes:
+  * la précision de positionnement ;
+  * la qualité des polices.
--  the positioning accuracy, and
+Dans le cas où la sortie <latex>\TeX</latex> ou <latex>\LaTeX</latex> est envoyée directement à une imprimante, dans le langage « natif » de l'imprimante, il est clair que le processeur DVI doit connaître tous ces détails et doit tenir compte des deux types de résolution.
--  the quality of the fonts.
-In the case where (La)TeX output is being sent direct to a printer,
+Dans le cas où la sortie est envoyée vers un format intermédiaire, qui a un potentiel d'impression (ou d'affichage), nous ne savons pas comment le traducteur final, qui se connecte directement à l'imprimante (ou à l'écran), a connaissance des propriétés de l'appareil : le processeur DVI n'a pas besoin de le savoir et ne doit pas prétendre le deviner.
-in the printer's "native" language, it's plain that the DVI
-processor must know all such details, and must take detailed account
-of both types of resolution.
-In the case where output is being sent to an intermediate distribution
