In Epson emulation mode, the SureMark printer supports all Epson commands
except the page mode commands and smoothing. Table 30 lists the commands that
are not supported.

Connectivity differences
The connectivity differences between an Epson single-station printer and the
SureMark printers are:
v The Epson printer offers a parallel interface that the SureMark printer does not
support.
v The following EIA-232 modes of communication, which are supported by the
Epson single-station printer, are not supported by the SureMark printer:
– 2400 kbps and 4800 kbps baud
– 7 bits of data
– Parity
– More than one stop bit
– 25-pin D shell
v To attach the printer to a standard PC serial port:
– The Epson single-station printer requires a Null Modem cable.
– The SureMark requires a standard 9-pin D-shell EIA-232 cable.
Functional differences
The following limitations must be considered when using a single-station SureMark
printer to emulate an Epson single-station printer:
v When applications switch from Epson printers to IBM printers, there is sometimes
a difference in the receipt line spacing. The receipt appears double spaced
because, by default, the SureMark printer treats carriage returns (CRs) the same
as line feeds (LFs). To change this behavior see “Mode Option” MCT #30 (1E
hex) in Table 17 on page 125.
v To provide a more seamless transition between OPOS-driven Epson and IBM
printers, IBM now supports an OEM Printer Emulation setting in the OPOS
printer device configuration dialog. Enable this setting to produce behavior that is
more consistent with that of an Epson printer. (Refer to the Application
Programming Guide for your driver.)
