We are trying to change our print format from the middle receipt to the one on the left. We have a lot of white space at the bottom of the receipt
This space is coming from the current used print format. You need to check the print format code and change it.
Print Preview Different From Print Output
Yup. @bghayad is correct. This is a print format issue. The printer doesn’t know when to stop printing and cut the paper
So it depends on the size that is written in the format print code. Could be the size is long?
