===== Using the Printer Card =====

Printing to a McGill uPrint printer with the ACELab printer card can be done both from the **command line** and from the **GUI**.

==== List Printers ====
First check to see if the printers are available on your machine:
<code>
me@ace-ws-00:~$ lpstat -p
</code>

Output example will be vary on Ubuntu 16 and Ubuntu 18

<code>
printer HP-color-laserjet is idle.  enabled since Thu 26 Jan 2017 02:32:24 PM EST
printer McGill_Color is idle.  enabled since Thu 16 Feb 2017 02:43:59 PM EST
printer mcgill_mono is idle.  enabled since Thu 16 Feb 2017 02:44:14 PM EST
printer mcgill_mono_beta is idle.  enabled since Thu 16 Feb 2017 02:44:00 PM EST
</code>

You can see here a local printer and the McGill uPrint printers.

==== How to print ====

* 2 UPrint cards in NW (amni16 in NW145 and amni22 in NW136)

* 1 uPrint card in 527 (amni17)

=== Print out from the command line ===

To print a file named myfile.txt to mcgill_mono using the amni16 “Evans Lab Students” account:

<code>
me@ace-ws-00:~$ lp -U amni16 -d mcgill_mono myfile.txt
request id is mcgill_mono-117 (1 file(s))
</code>
Then, find the amni16 uPrint card and release the job at the printer.

=== Print out from the GUI ===

* //Create a directory and file under your home directory//
<code>
mkdir -p ~/.cups/client.conf
touch ~/.cups/client.conf
</code>
* //Add Lab uPrint card name (amni16 e.g.) into client.conf file//
<code>
echo 'USER amni16'>> ~/.cups/client.conf
</code>
* //Set a default printer in ~/.cups/lpoptions//
<code>
lpoptions -d mcgill_mono
</code>
note: you can add all available printers into ~/.cups/lpoptions by editing the file
<code>
XXX@ace-ws-XX:~$ cat .cups/lpoptions 
McGill_Color
mcgill_mono
mcgill_mono_beta
</code>
