Commands with Limited Support in Emulation Mode
The SureMark single-station printers in SBCS mode can emulate an Epson
single-station printer. Emulation mode provides full support for most Epson
commands. However, some commands are supported partially and a few
commands are not supported at all. This section describes the commands that have
each of the three levels of support and also lists the connectivity differences
between an Epson single-station printer and the SureMark single-station printers.
Commands Supported in Emulation Mode
The commands listed in Table 20 are supported in Epson emulation mode.
However, there will be some differences in the printed output, because of different
dot pitches in the print heads and the minimum distance that the paper feed motors
can move the paper. These differences will appear when there are a number of
printed lines, and the method of aligning the data is different.
Examples of the printed differences that might occur:
v Logos will appear smaller in emulation mode. The logo will still contain the same
number of dots in the width and height. However, because the SureMark print
head has a finer dot pitch, the logo will appear smaller. If text is aligned around
the logo, the text on receipts that are printed in emulation mode might not line up
the same as receipts that are printed on the Epson printer.
v If one line is aligned using spaces and another line is aligned using the relative
position commands, the data might appear misaligned. The commands, such as
the relative position and margin commands, that use the minimum unit of motion
values are based on a fraction of an inch, which eliminates the differences in the
dot pitch. Tabs and spaces are subject to pitch differences.
