Strong cancel data
When 16KB DC1 is sent to the head of each job, the printer performs a 
special initialization operation. 
Refer to 1.4.9 Initialization (p.104) for this initialization operation.
†
Skip reading of irregular data„
Unprintable characters
It doesnt print characters including ASCII code with text print mode.
NOTE:0Ah, 0Ch, 0Dh, 11h, and 1Bh are ESCP command supported by 
the printer. The printer judges the command at the same time and 
decides whether to print it.
„
Job time out
Refer to 1.4.4.11 Job Time-out Setting (p.54).
„
Preventing the remaining data from being printed on the second cut 
sheet
If the print data size is larger than the maximum data size that can be 
printed on a single sheet (manual feed/ ASF), the remaining data that 
cannot be printed on the first sheet is not printed on the second sheet.
The remaining print data (graphic data) is ignored, and the next new 
print data is printed from the top of the second paper.

When ST of Type-B I/F sets ON State-Reply, BDC-ST is sent through DBIN- 
register. When State Reply is started, Start and End of BDC-ST characters 
are announced by sending the Main command (0Eh).
NOTE:The BDC-ST is only sent when Type-B Lv2 is used.
TYPE-B LEVEL 3 PACKET MODE
Communication between Type-B I/F card and Printer corresponds to Type-B 
Level 3 (Packet Mode) Communication Specification. (IEEE P1284.4 (Draft 
1.50) compliant)†
Packet Mode Shifting
To shift to Type-B Level 3 Packet Mode, Option Card needs to correspond 
to Type-B Level 3 (D4 character string need to be added to Option Type 
character string). If Option Card that is non-Type B Level 3 
correspondence is inserted, Type-B sends error.

Supported Packet
Apply the following communication packet.

Local MIB
According to Type-B Level 3 Packet Mode correspondence, it corresponds 
to Local MIB (Type-B/EMAP). 
Refer to 1.4.7 MIB Function (p.102).
1.6.4  SupplementsRECEIVED BUFFER FULL OPERATION
If the available buffer becomes less than 32Kbyte while receiving data via USB 
I/F or 1394 I/F with no error occurring (including Standby), the printer limits its 
receivable data size to 40 bytes/sec until the available buffer becomes 36kbyte 
or more to avoid the timeout of the host computer.
NOTE:This status is not occurred in Type-B Level 3 Packet Mode for 
Credit administration.INTERFACE SELECTION
The printer has IEEE1394 interface, USB 2.0 interface, and optional interface. 
These interfaces are selected manually by the default setting mode or selected 
automatically.†
Manual Selection
One of 3 interfaces can be selected; IEEE1394 interface, USB 2.0 
interface, optional interface.
NOTE:As for Stylus Pro 4450/4880/4880C, the IEEE1394 interface is not 
mounted and the network interface is assigned as the optional 
interface.
†
Automatic Selection
Select an interface that the printer first received data after power was ON. 
If it passes period of time (10 seconds) after interruption of data receiving, 
it will be in idle status (any interface is not selected) and will select an 
interface which the printer next receives data first.
NOTE:This status is not implemented in Type-B Level 3 Packet Mode 
for Channel administration.
To move to idle status, close the 
DataChannel.
†
Interface Selection and Interface State
When the printer is initialized or returned to the idle status (any interface is 
not selected), the USB interface becomes non-NACK reply status, and the 
option interface resets OFF-LINE bit of Main Status Register (MNSTS).  Table 1-53.
