Looking for just an accurate laser printer...

 

Having spent a lot of time scaling a drawing to a kit, doublechecked monitor scaling wasn't messing with me.

Now it turns out a print, set at 'print at 100%", comes out at 110% or so, and I had to do test prints in 1% steps until I hit 92%!

 

The printer is a simple Laserjet 1102w, so pretty much a cheapie.

Any tips on making it do what I want, and print at 100%?

This is likely not about the printer but about the software you are using. 
So the questions are 

- what operating system? 
- what software? 

- what kind of image (raster / vector)?

Win 11

Regular HP driver

Tried with Gimp, paint, photoviewer

Image type, .jpg, and .Tif

Document settings are correct, (A4, landscape).

Dpi settings tried 600 - 1200

driver 50157037_1

Might be too obvious (but it caught me out in the past) - check that your selected paper size matches the paper you are using and that you have not selected the 'scale to fit' option on the print settings. The discrepancy might simply be having the print settings for A4 and you are using US Letter size (or vice versa)

nope, work in IT for 20+ years now, so that's stuff I check.

I just tried printing a jpg from windows photo viewer and chose the scaled option set to 100% from page set up in printer properties.

Seemed to work ok,, have you got that option in your printer properties

This is odd. 
Gimp is the right tool, not known to be too "user friendly" and doing not what was asked for so let's stick with Gimp. 
I regularly print drawings and decals and one of my printers is HP so I haven't seen any problems with scaling. 

How about 
- choose two distinct point on your pic
- switch Gimp units to millimeters, use ruller tool to measure the distance between these points 
- print with no scaling 

- measure the distant between these points with "real" ruller

- divide one measure by another, this will give you the necessary scaling factor 

- scale image, print again

 

Not ideal but will do the trick

Thanks, but that is what I'm trying to avoid!

That is how I checked for size (never mind just overlaying the part, and noticing "that's a bit big"

I'm all over the Gimp fora atm, trying to find a solution.

How do you know that your pic is of correct size?
It depends on the resolution, Gimp ruller uses image resolution to calculate measures so it is worth checking that the resolution of the pic is set correctly. Again, I would use ruller tool to measure the distance between two known points, maybe the image needs scaling. 
I would only consider further brainstorming then this possibility is eliminated

That's what I did, measure two points, then scale the image accordingly (even measured on screen, set windows scaling to 100%, set image in Gimp to 100%, measured, held the part up.....🤷‍♂️
