Printing labels

Open antonis27 opened this issue 1 year ago • 3 comments

I would like to print labels to a thermal printer. If I know the height of each label, can I dynamically add empty lines to reach the label height? If so, do I need to get the current height of each label and compare it with the remaining space? Is it possible to get the current height ?

Someone already do that with this library, he used dot feed to align printing to the next sticker.

I tried to use dotsFeedPaper, but when I set dotsFeedPaper to 255, the position on the next label changed and is not at the correct position. I also noticed in some posts that there might be an issue with the maxValue of dotsFeedPaper and that larger feed values don't work as expected.

Printing dots to determine is a long and unstable process since the distances between the labels ( pages) may not be divided perfectly into dots. On the other hand, some printers have pagemode and related commands (like GotoNextLabel()). Is there a way to initiate these modes using this library? I mean, can we send raw commands to the printer?
