Hi Hank, here is my letter to LightBurn and down the end is there answer:
Noooooooooooooo,
Something wrong with LightBurn. I printed on my hpdeskjet 5550 and it came out 16mmx89,6mm
There are nothing wrong with my printers, I do have 50 other programs, well no , but Photoshop, office, Publisher, EmClient, visma Förening, Ashampo PDF , ACD See Photo Studio and do not no how many more and they all are working very well. Never had any
problems writing but now from LightBurn
What is wrong???
And as I said earlier, it is as you can see, smaller than an A4 paper. It is 120 mm x 21 mm. A4 is 210mm x 297mm

Next time, this time please read my letter better and try to understand my poor English. The print is smaller than A4 and is
not writing what I whant.
This is what Hank writes.
I just tried printing a QR code that is 1" (25.4mm) square and it printed at 0.39" (9.9mm).
That’s pretty useless.
Is there a trick to making things print correct size?
Have a nice day 
Ulf

Hi Ulf,
Check your printer settings. I checked this myself and my printer was set to resize items for printing. In general if the image on screen is smaller than the page size of the printer, it will print at exact size. If it is larger than the page size of the printer, it will scale to fit, though as mentioned you should check your printer settings.
Cheers,

Hej,
When I have a rectangle with text in it in LightBurn 21 x 120 mm and
printing it out on my printer (paper) it will not keep the measure. It
is only 16 mm x 92 mm. I do use Arkiv, print and print colors no diff.
How is that?
For ex in Carveco it comes out in right dimensions.
It does not matter what printer I use, Brother or HP
Why do I print on paper? Well it is easy to see if it comes out as
wanted and simple to use to compare with instead
of burning on wood
Have a nice day 
Ulf
