Driver Information And Download Destination; Epson Opos Adk - Epson TM L90 Technical Reference Manual

Note:
With TM-L90, a USB device driver is required for USB specification printers, and an IP setting utility is
required for Ethernet specification printers. For details, refer to the packaged APD manual. With the TM-
L90 peeler specification, an IP setting utility is required for Ethernet specification printers. For details,
refer to the packaged APD manual.
When the TM-L90 is connected via a serial interface, it is recommended to use the printer resident font
since use of the TrueType font will decrease printing speed due to the transfer speed of the serial interface.
For how to use the resident font, refer to the PDF User's Manual of APD.
The other interfaces (parallel, USB, Ethernet) do not pose problems in terms of the transfer speed but may
have some influence on customer applications. In that case, use the printer resident font. When OPOS is
used, this problem does not arise because only the printer resident font is available.
