Moving from the A756 to the A776 (Emulation commands)

These commands are handled differently when the A776 is in A756 emulation mode.

1B	47	enable double strike (the difference is no parameter byte req’d)
1B	48	disable double strike
1B	4C...	double density graphics command sequence

Moving from the A756, A758, or A760 to the A776 (Slip differences)

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 firmware 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.

	A756, A758, A760	A776
Impact Station Print Zone	4.7 inches	3 inches
Characters/row – Normal Mode	66	42
Characters/row – Compressed Mode	80	51

See Chapter 4: Programming the Printer for more details about the slip print zones.

Some commands have new functions for the slip and can be configured to be enabled or disabled on the slip. Existing applications that use these functions on the receipt but not on the slip may need to be disabled manually for the slip. The default is disabled for the slip.
