Because the printer is being shared between the parallel port and the 3270 host, careful attention should be paid to setting up the PC so that jobs are not automatically terminated because the printer is. busy.
This problem may be helped by setting the PC timer “off by writing "mode 1pt1:,,p" (in case of an LPT1 printer) in DOS.
Use of the DOS PRINT command or a spooling program for the PC is recommended.
If your printer supports intelligent Emulation Switching (IES), make sure your printer’s IES timeout period is less than the command 50 timeout setting.
EXAMPLE: &%Z50,10 Sets the time interval to 10 seconds
COMMAND 51: COAX PORT TIME OUT
Selects the time interval that the interface waits for receipt of additional data from the coax host before automatically switching to check for data from the alternate (PC) host.
VALUE DESCRIPTION
00The interface never checks for parallel port data (parallel shared port is disabled).
01Time interval in number of seconds
to
*10 Factory Default is 10 seconds
NOTE: The alternate (PC) host is responsible for sending any needed format commands required by the printer prior to sending printable data.
If your printer supports Intelligent Emulation Switching (IES), make sure your printer’s IES timeout period is less than the command 51 timeout setting.
EXAMPLE: &%Z51,05 Sets the time interval to 5 seconds
