h1. Epilog Laser on Mac OS X 107

This is not working. For some reason, the printer driver is not generating proper postscript (only with Inkscape...) No idea why.

There is also a python version for this here:

<pre>

git clone http://www.as220.org/git/cups_fab.git

</pre>

And here is an adapted version that uses the PPD for parameters.

Download the attached cups-epilog.tar.gz file.

<pre>

tar -xvzf cups-epilog.tar.gz

cd cups-epilog/src

gcc -o epilog `cups-config --cflags` -funsigned-char cups-epilog.c `cups-config --libs`

sudo mv epilog /usr/libexec/cups/backend/

sudo chown root:wheel /usr/libexec/cups/backend/epilog

sudo launchctl unload /System/Library/LaunchDaemons/org.cups.cupsd.plist

sudo launchctl load /System/Library/LaunchDaemons/org.cups.cupsd.plist

</pre>

add printer

name the printer something that has to do with the material you are cutting

choose device epilog laser

device uri: epilog://<epilogIPhere>/Legend/vs=7/vp=100/r=600/

where:

<pre>

 * af	Auto focus (0=no, 1=yes)

 * r	Resolution 75-1200

 * rs	Raster speed 1-100

 * rp	Raster power 0-100

 * vs	Vector speed 1-100

 * vp	Vector power 1-100

 * vf		Vector frequency 10-5000

 * sc	Photograph screen size in pixels, 0=threshold, +ve=line, -ve=spot, used

 *      	in mono mode, default 8.

 * rm	Raster mode mono/grey/color

</pre>

make/manufacturer raw

model/driver raw

Adding class

* Under the Administration tab, click Add Class.

* Enter a Name, Description, Location and select the Members:

* #  Name = Queue Name (e.g. ZebraRAWClass)

* # Description = Human Readable Description (e.g. ZebraRaw)

* # Location = Human Readable Location (e.g. My Mac mini)

* # Members = the Queue Name of the new raw printer

make rgb postscript (.ps) files with only red (ff0000) and vectors that are .25 px wide

You need to get the QT SDK from here:

And boost

or

<pre>sudo port install boost</pre>
