PQ-8P, PQ-8S

Command Pass-Thru may change the horizontal spacing.

Although the command is displayed on the screen, the PQ-8 treats it as a command and does not print it. If part of the sequence is printed, an error has been made entering the codes. Check the document and make sure the correct format and EBCDIC hexadecimal characters are being used.

Avoid sending codes that would move the print position during Command Pass-Thru. Since the PQ-8 does not process these commands, it cannot keep track of the print position changes. This may affect the position of characters that follow the command and the page layout.

6.2 User-Defined Strings

To avoid keying in frequently used printer commands (which would appear in the document as hex values imbedded in Command Pass- Thru delimiters), you should take advantage of the User-Defined Strings feature.

Using Host/PC download command 04, assign the numbers 0 through 9 to frequently used printer command strings.

After a command string has been defined, activate it by typing the

delimiter (&% or alternate CPT start delimiter) followed by the string number (U0 through U9) into the document or on the screen. When the document or screen is printed, the PQ-8 will recognize the &%U and send the command assigned to the string number to the printer.

For example, if command number U1 is assigned to a command string to turn on shadowed printing (hex codes 1B 28 73 31 32 38 53) for a Lexmark 4039 printer, then simply enter &%U1 in the document at the point where shadow printing is to begin.

Some commands (such as emphasized (bold) printing) may continue until another string is encountered that returns printing to normal, or for some host systems, until the next page is sent to the printer.

The PQ-8 self-test prints out a list of command numbers and the command strings assigned to them.
