I apologize if I haven't tested out everything you suggested, as I thought
I did, where "google is your friend" was done well *before* I even opened
this thread.

So I've tested Libre Office, Irfanview, Paint Shop Pro, HP Deskjet 6940
printer driver, Adobe Reader, Sourceforge poster-printer beta 1.0, an older
version of fineprint for which I had a serial, all of which failed on the
first pass until I got to Rasterbator which worked easily on the first
pass, creating 4-page PDF with alignment marks and the non-printable
borders already lined off.

I apologize if I didn't test one of your suggestions.

Looking back at *all* your posts to see what I missed:

Create in LibreOffice Draw custom size paper, i.e. full scale 12"x18"
Do Tile printing

LibreOffice's "PowerPoint" is Impress not Draw. If you were making a
graphic then PowerPoint was the wrong too to start with. PowerPoint is
for presentations...multiple "slides". I would try exporting PowerPoint
slide as PDF then import PDF into LibreOffice Draw.

Illustrator, CorelDraw, Inkscape, ... closest thing MS made was Publisher.

As I have pointed out there are *free* applications at your disposal.

With the *proper* tool this is a snap:

(which appears to be Corel Draw which is not a freeware tool)
You can even set overlap and registration marks to facilitate the process.

It was CorelDraw but that was not my point. My point was
using a program specifically for "making signs" or other such graphics
is the best (and easiest) way to get the job done. You *could* use a
word processor or spreadsheet program to do the job but it would be
neither easy, nor "best", nor even suitable for the task.

If you resample a 1200x1800 to 3600x5400 you will lose clarity. The
"tween" pixels must be extrapolated.You cannot "gain" information that
does not exist. CSI on TV is really fantasy.

I thank you for letting me know that the one suggestion of yours that I
didn't already test was this thing called "Inkscape", which, googling,
appears to be somewhere he

But it's not there, so maybe it's here?

Which points to here for the download:

So you were right!

I'll install Inkscape as that seems to be the only vector-based
sign-creation with alignment marks and border control Windows freeware
you've suggested that I haven't already tested.

Thanks for reminding me of your helpful suggestion that I had missed.
