-The printer itself is a Lexmark E120n.

-It is reachable over the LAN, at ''drucker.realraum.at'', and you can print to it using JetDirect.

-===== LPRng configuration ======
+^ Printer ^ Where ^ Papersize ^ Colour ^ Tech ^ cost ^ recommended connection ^
+| HP LaserJet 8000          | W2 hallway | A4/A3 | no | laser | cheap        | via drucker.realraum.at |
+| HP Business Inkjet 2250tn | W1 CX      | A4    | yes | ink   | ~           | via USB                 |
+| HP Color Laserjet CP2025 | W2 hallway  | A4     | yes | laser | less cheap | via USB (LAN untested)  |
-You can use directly LPRng to print from your computer, no CUPS needed!
+==== Printing via drucker.realraum.at ====
-The packages you will need (on Debian Stretch) are:
+To view status of or cancel print-jobs use the [[http://drucker.realraum.at:631/jobs/|CUPS Administrative Interface]]
-  * ''printer-driver-hpijs''
-  * ''ghostscript''
-  * ''foomatic-filters'' and ''foomatic-db''
-  * ''lprng'' (obviously!)
-==== Enabling the LPRng daemon ====
+The BeagleBone drucker.realraum.at will automagically switch the big printer on and off.
-  sudo checkpc -f # Fix various directory permissions
+  * any system (experimental):
-  sudo systemctl enable lprng
+    * goto http://drucker.realraum.at
-  sudo systemctl start  lprng
+    * upload a ''.pdf'' or ''.ps'' or ''.png'' or ''.jpg'' file with A4 paper size
+    * wait up to 20 seconds
+  * on Linux:
+    * CUPS will automagically list the available printers without installing it in your printing dialog.
+    * All you need to do is
+      - be in the realraum Network
+      - select the desired printer when printing something
+  * on Windows:
+    - Browse to ''\\drucker.realraum.at\''
+    - Right click on ''HP Laserjet 8000 PCL fast'' and choose ''install''.
+    - Choose to select a custom printer driver
+    - Select ''HP Laserjet 5200 Series PCL 5'' or ''HP LaserJet PCLm Class Driver''  or download original Driver
+    - Print
-Autostarting the LPRng daemon is relatively safe: by default, it only listens on a UNIX socket.

-The printer driver needs a PPD file, that you can create out of the foomatic database as follows:
+=== known Problems with drucker.realraum.at BeagleBone ===
-  foomatic-ppdfile -p Lexmark-E120n | sudo tee /etc/lprng/Lexmark-E120n.ppd > /dev/null
+  * Printer does not power on: Wait, the script checks for print-jobs only every 30s. Also, some <del>morron</del>well-meaning-person might have disconnected the BeagleBone, the Printer or the power or switched off the printer manually.
+  * Does not print but printer powers on. (Printers displays "STANDBY" not "PROCESSING"): Check if green LEDs on Belkin USB-Hub are lit. If not, unplug USB-Hub from BeagleBone, unplug USB-Hub-Power and plug everything back in.
-==== Configuring LPRng ====
+  * If it does not work: Check if the tiny white usb-hub has power. Disconnect and Reconnect all USB-cables and power from the tiny white usb-hub. That should be all that's needed, unless the USB-LPT cable has a loose contact inside the cable.
-LPRng comes with an example ''/etc/printcap'' file, that you may or may not use.
+  * Printing slow: recently we switched the Laserjet from PCL driver (fast) back to PostScript-Driver (slow) since only the PostScript-Driver supports A3.
-In any case, here is the configuration you actually need:
-  .common:
+  * Injket Error page: The CUPS support for the 2250TN is poor. Currently there is a choice between one driver that crashes the printer after one page or another driver that prints successfully but with one error-page after each print-job. We choose the later.

-==== Make GTK 2 applications use LPRng ====
+  * It's printing garbage: Use the correct autodiscovered CUPS printer. Don't configure something yourself.
-Write ''gtk-print-backends = "file,lpr"'' in ''~/.gtkrc-2.0''.
+  * on a recent test, a 32 page paper printed, though on some pages only 66.6% text was printed. We assume it was the devils work, as no other possible reason or log entry came forth and plead guilty
-Unfortunately, AFAIK GTK 3 has no support for LPR.
+=== Trouble shooting===
+In the unlikely case that the printer does only print PS or PCL commands, abort the print job directly on the printer or you might end up with hundreds of useless pages.
