Canon PIXMA iP7220 and Graphtec - Print & cut projects for CD labels, case insert, and boxes

[Cool Games]

I tried on my own to get things to work but now need help as it may need re-programming by open source volunteers.

**New Canon PIXMA iP7220 Inkjet for CD labels
old Graphtec CC100-20 Craft Robo - print then cut - blade plotter
Both devices work on loaner latest MacOS with Easy PhotoPrinter and Silhouette Studio so suspect
Linux (Ubuntu Studio 17.04 on System 76 Lemur laptop)

I am testing by Canon printing CD template with registration marks then trace outline with pen in Craft Robo device.
I also can cut accurate size paper CD then tape to Tray J in Canon to not waste printable CDs.
Later I want to make case labels and boxes for CDs.

I suspect Inkscape changes are culprit.
DPI changed from 90 to 96 DPI as warned when loading the registration template SVG from ROBOCUT.

Canon CD Glabel printout is wrong place on CD in Tray J with Ubuntu drivers 5.2.12 from repository
Activity I find...
https://sourceforge.net/p/gimp-print/mailman/message/34558344/
and
http://gimp-print-devel.narkive.com/I65VHZKB/canon-mg6700-cd-tray-offsets-will-test
and WINE can't see USB printer to try to use Easy PhotoPrint EXE.

Robo Master EXE not seeing USB device.
Silhouette Studio won't install with wine.

Outline is not in right place using Inkscape-Silhouette extension.

or ROBOCUT from repository

How can I get to third parties to help fix GITHUB, SOURCEFORGE and WINE ?

I am trying Virtual Box with Windows 10 but HATE to use that much disc space just to print CD labels and make cutter projects !

Still waiting for fix or instructions for work around and now on Ubuntu Studio 18.04.

READ past 2012 comments on patch but not sure where to get and apply patch.

I can help debug and verify but I am not a programmer to be resposible for any fixes in sources.

I have installed and built from source 5.2.13 and am ready with 5.2.14 if there is any reason to install before released.
Driver: Canon iP7200 series - CUPS+Gutenprint v5.2.13 (color, 2-sided printing)
