Wrong scaling with "optimal" Printer settings for dymo 450 or just wrong settings?

Open freaky-m0 opened this issue 3 years ago • 4 comments

Hi,

I have a problem with the newest release on Windows 10 with my Dymo LabelWriter 450. I want to print a picture on the label (the original dymo software has horrible print quality with this and with Gimp I got no luck to print it in the right orientation) but when I print it without changing anything, the quality is not good (right on picture). When I set the printer to "optimal" or something else I get the result on the left... What am I doing wrong? Its with the 99012 labels. Thanks in advance! IMG_1261

It seems it doesn't matter which size of label I try. With the "optimal" (or 300x600dpi) settings it's always scaled like this. Even normal text labels. When I print a normal image (correct size in mm) with the windows print dialog, it work's fine. So I guess it's not the fault of the driver.

At least on linux I get weird results (like one print spanning multiple labels) when I select any printer resolution with two dpi numbers (e.g. 300x600dpi). When using something with only one dimension, then it works for me.

Hmm so it seems that there is something wrong with those settings. (300x600)

Hi, I can confirm this is an issue caused by DYMO's driver. The High Quality (300x600 dpi) setting causes faulty scaling by upscaling the image disproportionally. I'm currently trying to get this to work. Will get back to you if a solution presents itself. Current workaround is generating the source image in a wrongly scaled, "squished" way - half as high as it should be - that way the driver scales it up to the correct sizing.
