Overview of fonts and how to troubleshoot font problems in Microsoft Word. 11/4/2019. 10 minutes to read.
Applies to: Word 2016, Word 2013, Word 2010In this article SummaryThis article contains an overview of fonts. Additionally, it describes how to troubleshoot font problems in Microsoft Office Word 2007 and later. More Information Overview of fontsA font is a graphic design that is applied to a collection of numbers, symbols, and characters. A font specifies qualities such as typeface, size, spacing, and pitch. Fonts are used to print text on various output devices and to display text on the screen. Fonts have font styles such as italic, bold, and bold italic. Outline fontsTrueType fonts and OpenType fonts are outline fonts that are rendered from line commands and from curve commands.
OpenType is an extension of TrueType. Both TrueType fonts and OpenType fonts can be scaled and rotated. TrueType fonts and OpenType fonts look good in all sizes and on all output devices that are supported by Microsoft Windows. Screen fontsClearType fonts are screen fonts that are optimized for an LCD screen.
On an LCD screen, ClearType fonts use sub-pixel information to smooth out the fonts' jagged edges. Printer fontsIn most programs that support printing, you can select among different printer fonts. Printers that offer the widest assortment of fonts include laser printers, ink-jet printers, and dot-matrix printers.
You can divide printer fonts into the following three categories:.Internal fontsInternal fonts are also named resident fonts. Laser printers, ink-jet printers, and dot-matrix printers frequently use internal fonts. Internal fonts are already loaded into the printer's read-only memory (ROM).
Internal fonts are always available for printing.Cartridge fontsCartridge fonts are stored in a cartridge or in a card that plugs into the printer. To expand a printer's set of internal fonts, you can install font cartridges. Or, you can load fonts from software.Downloadable fontsDownloadable fonts are also named soft fonts. The computer sends downloadable fonts to the printer's memory when the fonts are required for printing. Laser printers and other page printers frequently use downloadable fonts.
Some dot-matrix printers also use them. To increase printer speed, you should install downloadable fonts locally on client computers that print to Windows print servers.For each document that you print, Windows may have to send the screen fonts and the downloadable fonts that the document requires to the printer. To increase printer speed, use the following techniques:. Use fonts that do not have to be downloaded, such as internal fonts or cartridge fonts. Some printers have a feature that enables the printer to keep a list of downloadable fonts. If your printer has this feature, make sure that you turn on the feature.Not all printers can use all three types of fonts.
For example, pen plotters cannot ordinarily use downloadable fonts. For more information about the types of fonts that you can use, see the printer's documentation.
Raster fontsRaster fonts are also named bitmapped fonts. They are stored as bitmaps.
A bitmap is a pattern of dots. Raster fonts are designed with a specific size and with a specific resolution for a specific printer. You cannot scale or rotate raster fonts. If a printer does not support raster fonts, it will not print them. The following fonts are the five raster fonts:. Courier. MS Sans Serif.
MS Serif. Small. SymbolVector fontsVector fonts are useful for output devices that cannot reproduce bitmaps. For example, pen plotters use vector fonts. Vector font characters are drawn with lines instead of with patterns of dots. You can scale characters to any size or to any aspect ratio. NotePanose font mapping information is stored with the font to describe the font's characteristics.
For example, these characteristics may include serif or sans serif, normal, bold, or italic. If no Panose information is available, the font appears at the bottom of the list, and it does not appear in the List fonts by similarity to box. How to troubleshoot font problems in Word 2007 and Word 2010 Before you start to troubleshoot font problemsBefore you start to troubleshoot font problems in Word 2007 and Word 2010, review the following general topics:.Always make sure that you have installed the latest service pack for your version of Windows. Several font problems have been corrected in Windows service packs.The exact number of TrueType fonts that you can install depends on the length of the TrueType font names and of the TrueType file names.Basic steps to troubleshoot font problemsTo troubleshoot font problems in Word 2007 and Word 2010, follow these basic steps:.Make sure that you are using the correct printer driver.Your problem may be that the default printer driver in Windows is a generic/text only printer driver, an installed fax driver, or a similar driver. To change the printer driver that Microsoft Word uses, use one of the following methods.Important Do not select a generic/text only printer driver or an installed fax driver as your default printer in Windows.
In Word, click the Microsoft Office Button or File Tab (Word 2010), and then click Print. In the Namebox, click the name of an installed printer. Click Start, and then click Printers and Faxes. Right-click an installed printer, and then click Set as Default Printer.Check to see whether the problem occurs in a new document.Create a new Word document that is based on the Normal.dotm template.
To create a new document that is based on the global template, click the Microsoft Office Button, and then click New. Click Blank document, and then click Create.Based on what occurs in the new document, follow these steps:. In the new document, try a different font. If you have no problems when you use a different font, the problem may be related to a specific font in Windows. Go to the next step to continue to troubleshoot.
In the new document, use the font that you used in the original Word document. If the font problem no longer occurs in the new Word document, the original document is probably damaged.Note. If you used a template other than the Normal.dotm template to create the original Word document, the original document may be damaged. Or, the template from which the original document was created may be damaged. It is also possible that both the original document and its template are damaged.If the problem with a specific font persists in the new document, try to use the font in a new WordPad document. To create a WordPad document, click Start, point to All Programs, point to Accessories, and then click WordPad.If the problem that you experienced in Word persists in the WordPad document, the font is probably damaged.

Las operaciones de una base de datos relacional actúan en un conjunto completo de filas.Operations in a relational database act on a complete set of rows.El conjunto de filas que devuelve una instrucción SELECT está compuesto por todas las filas que satisfacen las condiciones de la cláusula WHERE de la instrucción.The set of rows returned by a SELECT statement consists of all the rows that satisfy the conditions in the WHERE clause of the statement.Este conjunto completo de filas que devuelve la instrucción se conoce como conjunto de resultados.This complete set of rows returned by the statement is known as the result set.Las aplicaciones, especialmente las que son interactivas y en línea, no funcionan siempre de forma eficaz con el conjunto de resultados completo como una unidad.Applications, especially those that are interactive and online, cannot always work effectively with the entire result set as a unit.Estas aplicaciones necesitan un mecanismo que trabaje con una fila o un pequeño bloque de filas cada vez.These applications need a mechanism to work with one row or a small block of rows at a time.Los cursores son una extensión de los conjuntos de resultados que proporcionan dicho mecanismo.Cursors are an extension to result sets that provide that mechanism.
Una biblioteca de cursores implementa un cursor.A cursor is implemented by a cursor library.Una biblioteca de cursores es software, que a menudo se implementa como parte de un sistema de base de datos o una API de acceso a datos, que se utiliza para administrar los atributos de los datos devueltos de un origen de datos (un conjunto de resultados).A cursor library is software, often implemented as a part of a database system or a data access API, that is used to manage attributes of data returned from a data source (a result set).Estos atributos incluyen la administración de simultaneidad, la posición en el conjunto de resultados, el número de filas devueltas y si puede moverse hacia delante o hacia atrás (o ambos) a través del conjunto de resultados (desplazamiento).These attributes include concurrency management, position in the result set, number of rows returned, and whether you can move forward or backward (or both) through the result set (scrollability).
Un cursor realiza un seguimiento de la posición en el conjunto de resultados y permite realizar varias operaciones fila a fila en un conjunto de resultados, con o sin volver a la tabla original.A cursor keeps track of the position in the result set, and allows you to perform multiple operations row by row against a result set, with or without returning to the original table.En otras palabras, los cursores devuelven conceptualmente un conjunto de resultados basado en las tablas de las bases de datos.In other words, cursors conceptually return a result set based on tables within the databases.El cursor se denomina así porque indica la posición actual en el conjunto de resultados, al igual que el cursor en la pantalla del equipo indica la posición actual.The cursor is so named because it indicates the current position in the result set, just as the cursor on a computer screen indicates current position.
Es importante familiarizarse con el concepto de cursores antes de continuar para obtener información sobre los detalles de su uso en ADO.It is important to become familiar with the concept of cursors before moving on to learn the specifics of their usage in ADO.
Mediante cursores, puede:Using cursors, you can:
Por ejemplo, imagine una aplicación que muestra una lista de productos disponibles para un comprador potencial.For example, consider an application that displays a list of available products to a potential buyer.El comprador se desplaza por la lista para ver los detalles y el costo del producto y, por último, selecciona un producto para su compra.The buyer scrolls through the list to see product details and cost, and finally selects a product for purchase.El desplazamiento y la selección adicionales se producen para el resto de la lista.Additional scrolling and selection occurs for the remainder of the list.En lo que respecta al comprador, los productos aparecen de uno en uno, pero la aplicación usa un cursor desplazable para examinar hacia arriba y hacia abajo por el conjunto de resultados.As far as the buyer is concerned, the products appear one at a time, but the application uses a scrollable cursor to browse up and down through the result set.
Puede utilizar cursores de varias maneras:You can use cursors in a variety of ways:
Los cursores de solo lectura ayudan a los usuarios a desplazarse por el conjunto de resultados, mientras que los cursores de lectura/escritura pueden implementar actualizaciones de filas individuales.Read-only cursors help users browse through the result set, and read/write cursors can implement individual row updates.Se pueden definir cursores complejos con conjuntos que apunten a las filas de la tabla base.Complex cursors can be defined with keysets that point back to base table rows.Aunque algunos cursores son de solo lectura en una dirección hacia delante, otros pueden desplazarse y proporcionar una actualización dinámica del conjunto de resultados basándose en los cambios que realizan otras aplicaciones en la base de datos.Although some cursors are read-only in a forward direction, others can move back and forth and provide a dynamic refresh of the result set based on changes that other applications are making to the database.
No todas las aplicaciones necesitan usar cursores para obtener acceso a los datos o actualizarlos.Not all applications need to use cursors to access or update data.Algunas consultas simplemente no requieren la actualización directa de filas mediante un cursor.Some queries simply do not require direct row updating by using a cursor.Los cursores deben ser una de las últimas técnicas que elija para recuperar datos y, a continuación, debe elegir el cursor de impacto más bajo posible.Cursors should be one of the last techniques you choose to retrieve>Cuando se crea un conjunto de resultados mediante un procedimiento almacenado, el conjunto de resultados no se puede actualizar mediante métodos de edición o actualización de cursores.When you create a result set by using a stored procedure, the result set is not updateable using cursor edit or update methods.
SimultaneidadConcurrency
En algunas aplicaciones multiusuario es muy importante que los datos presentados al usuario final sean lo más actuales posible.In some multiuser applications it is very important for the data presented to the end user to be as current as possible.Un ejemplo clásico de este tipo de sistema es un sistema de reserva de una línea aérea, en el que muchos usuarios pueden estar contratando el mismo puesto en un vuelo determinado (y, por lo tanto, un único registro).A classic example of such a system is an airline reservation system, where many users might be contending for the same seat on a given flight (and therefore, a single record).En un caso como este, el diseño de la aplicación debe controlar las operaciones simultáneas en un único registro.In a case like this, the application design must handle concurrent operations on a single record.
En otras aplicaciones, la simultaneidad no es tan importante.In other applications, concurrency is not as important.En tales casos, no se puede justificar el gasto implicado en mantener los datos actualizados en todo momento.In such cases, the expense involved in keeping the data current at all times cannot be justified.
PosiciónPosition
Un cursor también realiza un seguimiento de la posición actual en un conjunto de resultados.A cursor also keeps track of the current position in a result set.Considere la posición del cursor como un puntero al registro actual, de manera similar a la forma en que un índice de matriz señala el valor en esa ubicación concreta de la matriz.Think of the cursor position as a pointer to the current record, similar to the way an array index points to the value at that particular location in the array.
DesplazamientoScrollability
El tipo de cursor empleado por la aplicación también afecta a la capacidad de moverse hacia delante y hacia atrás por las filas de un conjunto de resultados. a veces, esto se conoce como desplazamiento.The type of cursor employed by your application also affects the ability to move forward and backward through the rows in a result set; this is sometimes referred to as scrollability.La capacidad de avanzar y retroceder por un conjunto de resultados se agrega a la complejidad del cursor y, por tanto, es más costosa de implementar.The ability to move forward and backward through a result set adds to the complexity of the cursor, and is therefore more expensive to implement.Por esta razón, debe solicitar un cursor con esta funcionalidad solo cuando sea necesario.For this reason, you should ask for a cursor with this functionality only when necessary.
