    Having trouble printing on custom paper sizes. Can you help me figure out the max width I should use on a form for it to print nicely on receipt paper (72mm wide) with a default resolution of 203 dpi? Also, how can I shrink the blank spaces between lines on the form so that it isn't as long? Thanks!

    Form width is measure in pixels.  72mm equals roughly 272px.  Most formatting, including line spacing, can be updated using the form designer:

    Line spacing will be under the "Line Layout" tab. 

    If you want to decrease the spacing further, you can add this code to your form:


    .form-line,.form-input-wide {
        margin-top : -10px;
        margin-bottom : -10px;

    Increase the negative value to decrease the spacing.  Positive values will increase spacing.
