! — Format header

Every CPCL job opens with it: vertical offset, horizontal and vertical resolution (dpi), label height and copy count on one line.

Engine status: Rendered

This command produces visible output in the preview.

Syntax

! <offset> <xres> <yres> <h> <qty>

Example

! 0 200 200 210 1
PAGE-WIDTH 576
PRINT

Open this example in the preview →

Open the validator →

Rendered example

Output of the example above in our renderer (203 dpi). Not verified on a physical printer.

Parameters

Parameter	Meaning
`offset`	Vertical offset of the label; accepted, not applied by the Labelixa preview
`xres`	Horizontal resolution; accepted, the preview always draws at 203 dpi
`yres`	Vertical resolution; accepted, the preview always draws at 203 dpi
`h`	Label height in dots; the preview clamps it to 32–4064
`qty`	Number of copies; the preview counts 1–999

Common mistake

Leaving out the ! header: label height and copy count come only from it, so without it the preview falls back to a 600-dot height and the validator warns.
