Printer interfaces 145 When this is set, use the copy command to copy to the communications port again: copy 'filename' lptx Windows® 95/98/Me/2000, Windows NT 4.0, Windows XP, and Windows Vista®: Select Hardware in the Flow Control field for correct operation of the RS-232C serial interface while setting up your communications port. For more information, see "Setting up the communications port" on page 133. RS-232C port compatibility The RS-232C port (on the RS-232C Serial Interface Card or the RS-232C Serial/Parallel 1284-C Interface Card) is compatible with the Plug and Play External COM Device Draft Specification, Rev. 0.86. Devices that are compatible with Plug and Play COM can do the following: • Detect attachment of serial devices • Identify the device • Locate a driver for the device • Detect detachment of serial devices Network support The standard network connection or installed network connection enables you to connect your printer to a local area network (LAN). The following network interfaces are offered: • 10BaseT-Conforms to the IEEE 802.3i standard • 100BaseTX-Conforms to the IEEE 802.3u standard • 10BaseFL-Conforms to the IEEE 802.3j standard • 100BaseFX-Conforms to the IEEE 802.3u standard • 1000BaseT-Conforms to the IEEE 802.3ab standard • Wireless-Conforms to the IEEE 802.11b/g standard and the IEEE 802.11n draft 2.0 standard, if applicable For information on installing a print server in your printer, see the documentation that came with your printer. Input buffer The maximum size of the input buffer for each printer interface depends upon the amount of RAM memory installed. The input buffers serve the same purpose as a print spooler. The printer can allocate automatically the input buffers. Note: The size of the input buffer may be modified or disabled from the control panel menus or through MarkVision Enterprise. If NPAP is active on a port, two-thirds of the buffer memory are reserved for NPAP and one-third is set aside for the input buffer. If NPAP is not active, all the memory is available for the input buffer. The following table shows the sizes automatically selected for the buffers when the buffer size is set to Auto in the menus.

RS-232C port compatibility
The RS-232C port (on the RS-232C Serial Interface Card or the RS-232C Serial/Parallel 1284-C Interface Card)
is compatible with the Plug and Play External COM Device Draft Specification, Rev. 0.86.
Devices that are compatible with Plug and Play COM can do the following:
•
Detect attachment of serial devices
•
Identify the device
•
Locate a driver for the device
•
Detect detachment of serial devices
Network support
The standard network connection or installed network connection enables you to connect your printer to a
local area network (LAN). The following network interfaces are offered:
•
10BaseT—Conforms to the IEEE 802.3i standard
•
100BaseTX—Conforms to the IEEE 802.3u standard
•
10BaseFL—Conforms to the IEEE 802.3j standard
•
100BaseFX—Conforms to the IEEE 802.3u standard
•
1000BaseT—Conforms to the IEEE 802.3ab standard
•
Wireless—Conforms to the IEEE 802.11b/g standard and the IEEE 802.11n draft 2.0 standard, if applicable
For information on installing a print server in your printer, see the documentation that came with your printer.
Input buffer
The maximum size of the input buffer for each printer interface depends upon the amount of RAM memory
installed. The input buffers serve the same purpose as a print spooler. The printer can allocate automatically
the input buffers.
Note:
The size of the input buffer may be modified or disabled from the control panel menus or through
MarkVision Enterprise.
If NPAP is active on a port, two-thirds of the buffer memory are reserved for NPAP and one-third is set aside for
the input buffer. If NPAP is not active, all the memory is available for the input buffer.
The following table shows the sizes automatically selected for the buffers when the buffer size is set to Auto
in the menus.
