Getting Started
Calibrating a printer
Do it once per printer, then save it as a profile.
Calibration measures the difference between where ChequeKo asks your printer to put the text and where it actually lands, then stores the correction as a printer profile.
The calibration sheet prints a 100 mm measuring bar. Measure it with any ruler. If it does not measure 100 mm, your browser or printer driver is rescaling the page — fix that in the print dialog before adjusting any offsets, otherwise you will be correcting a moving target.
Once the bar measures correctly, use the printed grid to read how far off the fields are, then nudge in 0.5 mm, 1 mm, or 5 mm steps and re-test.
