English
Communication between the driver and a host-based printer is often through proprietary or undocumented protocols, making them functional only on the most common operating systems.
Context English Chinese (Simplified) (zh_CN) State
Most network printers understand print jobs sent with the <acronym>LPD</acronym> protocol. A print queue name can also be specified. Some printers process data differently depending on which queue is used. For example, a <literal>raw</literal> queue prints the data unchanged, while the <literal>text</literal> queue adds carriage returns to plain text. 大多数网络打印机可以认得使用<acronym>LPD</acronym>通信协定所送出的打印工作,打印队列(Print queue)的名称也会在这时指定。部份印表机会依据使用的队列来决定处理数据的方式,例如<literal>raw</literal>队列会打印原始数据,而<literal>text</literal>队列则会在纯文字上增加换行符号(Carriage return)。
Many network printers can also print data sent directly to port 9100. 大部份网络打印机也可打印直接传送到端口号9100的数据。
Wired network connections are usually the easiest to set up and give the fastest printing. For direct connection to the computer, <acronym>USB</acronym> is preferred for speed and simplicity. Parallel connections work but have limitations on cable length and speed. Serial connections are more difficult to configure. Cable wiring differs between models, and communication parameters like baud rate and parity bits must add to the complexity. Fortunately, serial printers are rare. 有线网路连线通常是安装最简单的方式,且可以提供快速的打印。若要直接连接到电脑,较建议使用<acronym>USB</acronym>,由于较快速、简单。并列联机仍然可以使用,但有缆线长度与速度上的限制。而序列联机则比较难设定,不同型号的缆线布线方式不同,且通信参数如传输速率及同位检查增加了复杂性,所幸序列打印机并不多。
Common Page Description Languages 常见的页面描述语言
Data sent to a printer must be in a language that the printer can understand. These languages are called Page Description Languages, or <acronym>PDL</acronym>s. 传送给打印机的数据必须使用打印机能够理解的语言,这些语言称为页面描述语言(Page Description Languages)或<acronym>PDL</acronym>。
<acronym>ASCII</acronym> <acronym>ASCII</acronym>
Plain <acronym>ASCII</acronym> text is the simplest way to send data to a printer. Characters correspond one to one with what will be printed: an <literal>A</literal> in the data prints an <literal>A</literal> on the page. Very little formatting is available. There is no way to select a font or proportional spacing. The forced simplicity of plain <acronym>ASCII</acronym> means that text can be printed straight from the computer with little or no encoding or translation. The printed output corresponds directly with what was sent. 纯<acronym>ASCII</acronym>文字是传送数据到打印机最简单的方式,一个字元对应一个要打印的文字:数据中的<literal>A</literal>会打印一个<literal>A</literal>在页面。可以使用的格式非常少,没有办法选择字体或者比例间距。强迫使用简单的纯<acronym>ASCII</acronym>为的是让文字可以直接从电脑打印只需一点或甚至不需要编码或转译,打印的结果可直接对应传送的内容。
Some inexpensive printers cannot print plain <acronym>ASCII</acronym> text. This makes them more difficult to set up, but it is usually still possible. 部份便宜打印机无法打印纯<acronym>ASCII</acronym>文字,这让这些打印机较难设定。
<trademark class="registered">PostScript</trademark> <trademark class="registered">PostScript</trademark>
<trademark class="registered">PostScript</trademark> is almost the opposite of <acronym>ASCII</acronym>. Rather than simple text, a <trademark class="registered">PostScript</trademark> program is a set of instructions that draw the final document. Different fonts and graphics can be used. However, this power comes at a price. The program that draws the page must be written. Usually this program is generated by application software, so the process is invisible to the user. <trademark class="registered">PostScript</trademark>与<acronym>ASCII</acronym>几乎相反,与简单的文字不同,<trademark class="registered">PostScript</trademark>程序语言有一套指令可以绘出最终所要的文件,可以使用不同的字体与图形,但是,这样强大的功能是有代价的,绘制页面需要搛写程序语言,通常这个程序语言会由应用程序产生,所以使用者是看不到的。
Inexpensive printers sometimes leave out <trademark class="registered">PostScript</trademark> compatibility as a cost-saving measure. 便宜的打印机有时会移除<trademark class="registered">PostScript</trademark>的兼容性来节省成本。
<acronym>PCL</acronym> (Printer Command Language) <acronym>PCL</acronym>(打印语言)
<acronym>PCL</acronym> is an extension of <acronym>ASCII</acronym>, adding escape sequences for formatting, font selection, and printing graphics. Many printers provide <acronym>PCL5</acronym> support. Some support the newer <acronym>PCL6</acronym> or <acronym>PCLXL</acronym>. These later versions are supersets of <acronym>PCL5</acronym> and can provide faster printing. <acronym>PCL</acronym>由<acronym>ASCII</acronym>延伸而来,加入了跳脱序列(Escape sequence)来标示格式、选择字体以及打印图型。大部份打印机都支持<acronym>PCL5</acronym>,少数支持较新的<acronym>PCL6</acronym>或<acronym>PCLXL</acronym>,这些后来的版本是<acronym>PCL5</acronym>的超集合(Superset),并可以提供更快的打印速度。
Host-Based 以主机为基础(Host-Based)
Manufacturers can reduce the cost of a printer by giving it a simple processor and very little memory. These printers are not capable of printing plain text. Instead, bitmaps of text and graphics are drawn by a driver on the host computer and then sent to the printer. These are called <emphasis>host-based</emphasis> printers. 制造商可能会使用简单的处理器和较小的內存来降低打印机的成本,这些打印机无法打印纯文字,相反的,文字与图形会先在机器上的驱动程序画完后传送到打印机。这些称为<emphasis>以主机为基础(Host-based)</emphasis>的打印机。
Communication between the driver and a host-based printer is often through proprietary or undocumented protocols, making them functional only on the most common operating systems. 驱动程序与以主机为基础的打印机通信通常会透过专用或无文件的通信协定,这让这些打印机只能在最常用的操作系统上运作。
Converting <trademark class="registered">PostScript</trademark> to Other <acronym>PDL</acronym>s 转换<trademark class="registered">PostScript</trademark>至其他<acronym>PDL</acronym>
Many applications from the Ports Collection and FreeBSD utilities produce <trademark class="registered">PostScript</trademark> output. This table shows the utilities available to convert that into other common <acronym>PDL</acronym>s: Port套件集与FreeBSD工具集有许多可以处理<trademark class="registered">PostScript</trademark>输出的应用程序,此表整理出了可转换<trademark class="registered">PostScript</trademark>成其他常用<acronym>PDL</acronym>的工具:
Output <acronym>PDL</acronym>s 输出<acronym>PDL</acronym>格式
Output <acronym>PDL</acronym> 输出<acronym>PDL</acronym>
Generated By 产生由
<acronym>PCL</acronym> or <acronym>PCL5</acronym> <acronym>PCL</acronym>或<acronym>PCL5</acronym>

<literal>-sDEVICE=ljet4</literal> for monochrome, <literal>-sDEVICE=cljet5</literal> for color 单色使用<literal>-sDEVICE=ljet4</literal>、彩色使用<literal>-sDEVICE=cljet5</literal>

For the easiest printing, choose a printer that supports <trademark class="registered">PostScript</trademark>. Printers that support <acronym>PCL</acronym> are the next preferred. With <package role="port">print/ghostscript9-base</package>, these printers can be used as if they understood <trademark class="registered">PostScript</trademark> natively. Printers that support <trademark class="registered">PostScript</trademark> or <acronym>PCL</acronym> directly almost always support direct printing of plain <acronym>ASCII</acronym> text files also. 为简化打印过程,请选择支持<trademark class="registered">PostScript</trademark>的打印机。其次是支持<acronym>PCL</acronym>的打印机。通过使用<package role="port">print/ghostscript9-base</package>,这些打印机可以直接打印<trademark class="registered">PostScript</trademark>文件。支持<trademark class="registered">PostScript</trademark>或<acronym>PCL</acronym>的打印机几乎总是支持直接打印纯<acronym>ASCII</acronym>文本文件。
