Moving from the A756, A758, or A760 to the A776 (Slip dierences)
The impact station print zone on the A760 is 4.7 inches wide and the print zone on the A776 is 3.0 inches. To compensate for
the narrower print zone on the A776 the rmware will provide the following functionality:
1. For applications that currently use narrow forms with 42 or fewer columns, an option is provided to delete x leading
spaces. No application or form changes should be required.
2. For applications that use narrow forms with 51 or fewer columns, an option is provided to default to compressed
mode. No application or form changes should be required.
3. For applications using wide forms that print on less than 51 columns, options 1 and 2 above are combined with the
option to delete trailing spaces. There should be no changes required to the application but a new form will be
required.
4. For applications using wide forms that print on more than 51 columns, the data will wrap to the next line. If you
don’t want data to wrap you will need to change the application and the form.
