Printing Speed Mode Selection This printer is designed to control the printing speed according to the power supply voltage and printhead temperature. When the power supply voltage drops to the limit, the printer stops printing, then resumes the job at a slower speed to print the remaining data for the line. When the printhead temperature rises to the limit, the printer stops printing. Then it resumes printing at a slower speed if the printhead temperature recovers to the specified level. The printing speed mode is determined according to the flowchart shown in Page 1-6.

Description The strobe pulse. Read-in of data is performed at the falling edge of this pulse. The data 0 to data 7 signals represent data bits 0 to 7, respectively. Each signal is at a HIGH level when data is logical 1 and a LOW level when data is logical 0. This signal is a negative pulse indicating that the printer can again accept data. When this signal is at a HIGH level, the printer is not ready to accept data. When this signal is at a HIGH level, the paper empty status is detected. Always at a HIGH level when the printer is powered on. Not used. The falling edge of a negative pulse or a LOW signal on this line causes the printer to initialize. Minimum 50 us pulse is necessary. When the printer detects an error, this signal goes LOW. Not used. Pulled up to +5V via 3.9 K-ohm resistor. Pulled up to +5V via 3.3 K-ohm resistor. Chassis ground. Signal ground. Not connected.

1.4.5 Prevention Hosts from Data Transfer Time-out
Generally, hosts abandon data transfer to peripherals when a peripheral is BUSY continuously for dozens of seconds. To prevent this kind of time-out, the printer receives data very slowly, several bytes par minute, even the printer is in a busy state. This slowdown starts when the remainder of input buffer drops under several hundreds of bytes. Finally, the printer is BUSY continuously when the input buffer is full.
1.4.6 Interface Selection
The EPSON DLQ-3000+ has three types of interfaces: Parallel, Serial, and optional Type-B. Each interface can be selected manually by SelecType or automatically. Both modes are selected thorough the default setting mode.
Y Manual selection
One of the 3 interfaces can be selected by SelecType.
Y Automatic selection mode (Enabled by SelecType)
When the printer is powered on, the printer is initialized to the idle state scanning which interface receives data. Then the interface that receives data first is selected. When the host stops data transfer and the printer is in stand-by state for the seconds specified by SelecType, the printer is returned to the idle state. As long as the host sends data or the printer interface is busy state, the selected interface is left as it is.
Interface selection and interface state Interface selection and the corresponding interface states are as follows: Y When an interface other than parallel interface is selected, the interface goes into the BUSY state. Y When an interface other than serial interface is selected, the interface sends XOFF and sets the DTR signal MARK. Y When an interface other than optional interface is selected, the printer sets "OFFLINE" bit of MNSTS register to the optional interface. Y When the printer is initialized and returned to the idle state: · The parallel interface goes into ready state. · The serial interface sends XON and sets the DTR SPACE and the printer resets OFFLINE bit of MNSTS register to the optional interface. Note: An interrupt signal such as /INIT signal on the parallel interface is not effective while that interface is not selected.

Basically, all button operations are always effective except for the following cases. · During printing, only the Pause button is effective. · The SelecType button is only effective during the printer is in the standby status. · Load/Eject and "Pause" buttons are not effective during the SelecType mode. · Press the Pause button to stop printing. · Press the Pause button again to resume printing. Even if the Pause button is pressed, the interface continues to receive data until the input buffer is full and the CR moves to the ribbon changing position. Press the Pause and Load/Eject buttons simultaneously to initialize the printer. Refer to Section 1.5.5.

When the printer is in the tear-off state, these functions are performed after returning from the tear-off position. 2. Once a sheet is manually inserted, the printer enters manual insertion mode. While the mode is active, even if data is remaining in the buffer, the printer goes into a paper-out error state at each end of a sheet and waits for the next sheet to be inserted. CSF insertion is enabled again by loading sheets into the CSF or by initializing the printer. 3. and buttons are used as described below: · Pressing the button continuously feeds paper forward*/backward* with a increment of 1/180 inch. · Pressing the button continuously feeds paper forward*/backward* slowly. · When the printer is in the tear-off state, these buttons are used to adjust tear-off position.
