DUAL PRINTER SUPPLEMENT

<P1> - Print on ticket path #1. This command must be sent prior to any other data or commands for this ticket.

<P2> - Print on ticket path #2. This command must be sent prior to any other data or commands for this ticket.

NOTE: We recommend sending <P1> and <P2> on every ticket printed on a dual printer.

Commands which have been modified in relation to dual mode.

<pl> - Permanent print length command. This command was changed to allow both ticket paths to have a

permanent printing length. This command only works on the current ticket path. This means that if a change is

required on the other ticket path (or if both ticket paths need to be changed), a <P1> or <P2> command needs

to be issued before the print length command to determine which path will be affected. The <pl> command will

change the printing length of the ticket permanently by storing the new value in nonvolatile memory.

<PL> - Temporary print length command. The changes to this command are the same as the <pl> command

above, with the exception that the new values are not permanently stored. This routine only effects the program

variables and not the permanent variables. If the printer power is turned off, the printer will re-initialize the print

length to the previous values determined during initialization. The new print length becomes effective

immediately.

<dpl> - Delete permanent length command. This command will delete both permanent length variables

(permanent ticket length and permanent printing length). This command, like the <pl> command, only works on

the current path. If the non-active path or both paths need to be cleared, then a <P1> or <P2> command needs

to be issued before the <dpl> command. This command becomes effective only after the printer has been turn

off and back on.

<tl> - Permanent ticket length command. The ticket length command was changed to effect both paths. This

routine only works on the current path. If both paths need to be changed, send <P1> or <P2> before the ticket

length command. This routine affects both permanent and program variables and become effective

immediately. When the printer is turned off and back on, the stored ticket length will be used and the tickets will

not be measured. The permanent ticket length will be in effect until the delete permanent length command

(<dpl>) is sent.

<h> - Print / Cut and hold ticket image. This command is not applicable to Mag and Dual printers.

<r> - Print / No Cut and hold ticket image. This command is not applicable to Mag and Dual printers.

Brief comparison of the different dual modes.

Dual Mode

Paths can be different sizes (both paths are measured).

Both paths must be loaded at all times.

Does not distinguish status messages.

Printer goes busy if it runs out of paper on either side.

Dual Supply Mode

Paths must be the same size (only one path is measured).

Only one path needs to be loaded.

Does not distinguish status messages.

Automatically prints on the other side after running out of paper.

Ventek Dual Supply Mode

Paths can be different sizes (both paths are measured).

Only one path needs to loaded.

Distinguishes status messages with path number.

Automatically purges all remaining data on a path if it runs out of paper.
