77
78 Pages are counted by the printers and quota system. In **duplex** mode (default) the count is per printed side of the paper. Color pages count double that of black and white pages. A3 pages count as two A4 pages. The page count will be displayed on the cardreader during printing and changes accordingly.

102 == Printing using various programs ==
103
104 === Printing with Document Viewer (Linux): ===
105
106 The first clues to the error can already be found here
107
108 The print menu can be called up with **File** → **Print** (Alternativ: **Strg+P**).
109
110 *First setting:
111
112 When your printing for the first time, some default settings need to be changed, otherwise the printers will not be able to print your received job. These are the settings for page size and Paper Scource. Since the printers are loaded with A3 and A4 size paper, error messages sometimes occur if the job was not sent in either format. And since the paper size is clearly linked to the paper source, the default value **Tray 1** (A3) is not always correct. It should be configured as follows:
113
114 [[image:print1.png||width="550"]]
115
116 Adjust color:
117
118 If you want to print in color, you should not click on Color, but on Advanced. **Automatic** means colored here.
119
120 [[image:print2.png||width="550"]]
121
122 Send a print job:
123
124 As already mentioned in the topic Available printers, check that followme is selected before sending your Print job. In this step, you should also select the number of copies that you need.
125

127
128 == Troubleshooting ==
129
130 === I clicked on print, but the printer just does not print! ===
131
132 ==== Case 1 - Is there enough quota? ====
133
134 In the Linux machines simply select **Applications** -> **System** -> **Print Quota**
135
136 or just enter in Terminal (in the Computer hall under **Applications** -> **Accessories** -> **Terminal**)
137 {{{lpquota }}}
138 and check how many pages are available. The output is similar to this:
139
140 {{{|===== Abfrage des Druckerquotas fuer 'user' =====|
141
142 Kontingent 300 Seiten
143
144
145 }}}
146
147 Often, problems are occured when you dont have enough quota left to print a document. This must then be purchased again from the Fachschaft.
148
149 ==== Case 2 - I have enough quota - but no expression ====
150
151 Has the queue **followme** been selected?
152
153 In some cases the printer has not been selected, a click has been made or **Print to File** has been specified. In the lab currently only the queue **followme** configured.
154
155 Will you print directly from Firefox? In this case it often helps to select **Print to file ...** in Firefox and create a PDF file. This can then usually be printed out without any problems.
156
157 ==== Case 3 - I selected **followme** and quota - but no printout ====
158
159 Just have a look at our helpdesk (Kleine Rechhnerhalle 00.07.023 in the rear). It may be necessary to refill paper or it may be a different error condition that needs to be resolved.
