10 | ||
11 | <P>CUPS is the software you use to print from applications like the web browser | |
12 | you are using to read this page. It converts the <em>page descriptions</em> | |
13 | produced by your application (put a paragraph here, draw a line there, and so | |
14 | forth) into something your printer can understand and then sends the information | |
15 | to the printer for printing.</P> | |
16 | ||
17 | <P>Now, since every printer manufacturer does things differently, printing can | |
18 | be very complicated. CUPS does its best to hide this from you and your | |
19 | application so that you can concentrate on printing and less on <em>how</em> to | |
20 | print. Generally, the only time you need to know anything about your printer is | |
21 | when you use it for the first time, and even then CUPS can often figure things | |
22 | out on its own.</P> | |
23 | ||
24 | <H2 CLASS="title"><A NAME="WORK">How Does It Work?</A></H2> | |
25 | ||
26 | <P>The first time you print to a printer, CUPS creates a <em>queue</em> to keep | |
27 | track of the current status of the printer (everything OK, out of paper, etc.) | |
28 | and any pages you have printed. Most of the time the queue points to a printer | |
29 | connected directly to your computer via a USB port, however it can | |
30 | also point to a printer on your network, a printer on the Internet, or multiple | |
31 | printers depending on the configuration. Regardless of <em>where</em> the queue | |
32 | points, it will look like any other printer to you and your applications.</P> | |
33 | ||
34 | <P>Every time you print something, CUPS creates a <em>job</em> which contains | |
35 | the queue you are sending the print to, the name of the document you are | |
36 | printing, and the page descriptions. Job are numbered (queue-1, queue-2, and so | |
37 | forth) so you can monitor the job as it is printed or cancel it if you see a | |
38 | mistake. When CUPS gets a job for printing, it determines the best programs | |
39 | (<em>filters</em>, <em>printer drivers</em>, <em>port monitors</em>, and | |
40 | <em>backends</em>) to convert the pages into a printable format and then runs | |
41 | them to actually print the job.</P> | |
42 | ||
43 | <P>When the print job is completely printed, CUPS removes the job from the queue | |
44 | and moves on to any other jobs you have submitted. You can also be notified when | |
45 | the job is finished, or if there are any errors during printing, in several | |
46 | different ways.</P> | |

50 | <P>Click on the <var>Administration</var> tab. Click on the <var>Add Printer</var> button and follow the prompts.</P> | |
51 | ||
52 | <BLOCKQUOTE>When you are asked for a username and password, enter your login username and password or the "root" username and password. On macOS<sup>®</sup>, the login username (or "short name") is typically your first and last name in lowercase.</BLOCKQUOTE> | |
53 | ||
54 | <P>After the printer is added, CUPS will ask you to set the default printer | |
55 | options (paper size, output mode, etc.) for the printer. Make any changes as | |
56 | needed and then click on the <VAR>Set Default Options</VAR> button to save | |
57 | them. Some printers also support auto-configuration - click on the <VAR>Query | |
58 | Printer for Default Options</VAR> button to update the options automatically.</P> | |
59 | ||
60 | <P>Once you have added the printer, you can print to it from any application. | |
61 | You can also choose <VAR>Print Test Page</VAR> from the maintenance menu to print | |
62 | a simple test page and verify that everything is working properly.</P> | |
