ETHERNET TO TWINAX/COAX PRINT SERVER

h. Command Pass-Thru: Command Pass-Thru (CPT) is a useful feature that

allows access to printer features that may not be available through the

standard ASCII driver. When using CPT, printer-specific commands are

sent with the print data from the host. The commands are in EBCDIC hex

format and are flagged with the CPT identifiers &%. When the print

server receives CPT commands, it will not attempt to interpret them, but

will “pass the command through” to the printer. The options are No and

Yes (default).

5. If there are any other configuration changes you wish to make, do so. Then

click on the Apply Changes button and reset the print server to complete the

process.

7.4 Command Pass-Through

The Black Box Command Pass-Thru (CPT) feature can be used to access all of the

built-in features of a SCS or SCS/DSC printer, even if those features are not

normally available through the ASCII host software, especially if you must use a

generic print driver (such as in Windows). Printer-specific command sequences are

inserted into the data sent to the twinax or 3270-coax non-IPDS printer from the

host. The Print Box recognizes these special sequences and “passes the command

through” to the printer. The steps below describe how to use Command Pass-Thru.

1. Find the command for the print feature in the printer’s manual.

2. Convert the printer command to EBCDIC hexadecimal.

3. Place the Command Pass-Thru delimiter &% into the document at the point

where the feature is to take effect. This signals the start of the print feature.

Enter the printer command in EBCDIC hexadecimal code, then enter the

delimiter &% again. You may enter a space between hexadecimal code pairs

to make the command easier to read; however, do not put spaces between the

delimiter and the hexadecimal characters.

4. To change the print feature back, move the cursor to the point in the text

where the print feature is to be changed. Enter the delimiter, the new printer

command, and then the delimiter again.

For example:

2B D2 04 29 00 0F is the command in EBCDIC hexadecimal code for 15 CPI

printing on printers supporting this feature. 2B D2 04 29 00 0A is the

command in hexadecimal for 10 CPI printing. So, to begin 15 CPI printing,

enter the command as follows:
