Poster Printing

Basic information regarding the poster printer can be found here and here. Note that parts of the infos there are misleading or maybe outdated.

Short how-to for printing a poster (format A0)

Open the poster with your preferred reader. Supported formats (probably) are DVI, PDF and PostScript. The easiest/best format usually is PDF.
Send your print request to the printer queue zedat_poster5_a0. You have to supply your file either in A0 or in A4 format. If you use A4 the printer will rescale your file from A4 to A0. Note that this may cause quality loss.
Go to the PrintService Website and login. Under "orders" (Aufträge) you should now see your request pending (at most 1-2 minutes after you sent the request). Here you have the opportunity to see a preview of your poster. If you are happy with the preview you can confirm your poster request (freigeben) and put the job into the real printing queue. Your poster will not be printed unless you do this!
When the poster is finished you can pick it up at room Bora nearby the Zedat PC-Pools. Since the poster will be printed on an even larger piece of paper you will also find a device there to remove the white borders from your poster.

You can only print one poster at a time to avoid misprints.
On the PrintService Website you can check the printer queue (Druckerstatus) for the printer poster5 in order to see how many print jobs are currently pending for this device.
Telling by experience, the printer takes about 15 minutes per poster.
There seems to be no way to see what your current position in the queue is. It seems to follow a first-come-first-serve principle, however.
Once your job is finished it simply vanishes from the list of open print orders on the PrintService Website. You will get no notification via email or whatsoever.
If you submit a poster that turns out to be in too poor quality, then it is possible that the PrintService stops/pauses your job even if you confirmed it already. In that case you should try to solve the quality issue and resubmit your request.
There is a known issue of text fonts not scaling properly from A4 to A0. The solution to this is to explicitly specify the paper format as A0 in the printer dialog settings in order to let your computer do the rescaling instead of the printer.
