Problem with printing pdf documents?

Question

Seal

the task looks like this: to facilitate the process of receiving goods from suppliers and relieve warehouse employees.
solution: to shift to suppliers the task of labeling with a barcode, the goods that they ship to us.
implementation: together with information about our need, we send a link to a pdf document , where there are already generated stickers. stickers are printed on conventional laser printers on self-adhesive die-cutting. here's a picture of that cut.
what is the problem: when printing, acrobat scales any document up to 94% -96%.
this results in barcodes being unreadable. despite having VERY detailed instructions, suppliers' employees cannot print without scaling. the reason is carelessness.
here is such a situation.
I will be grateful for recommendations.

Answer 1

See the help section in Acrobat:
"Create print presets
A PDF can contain a set of print presets, a group of document-specific values ​​that is used to set basic print options. By creating a print preset for a document, you can avoid manually setting certain options in the Print dialog box each time you print the document. It's best to define print settings for a PDF at the time that you create it, but print presets provide a means to add basic print settings to a PDF at any time.
1. Choose File > Properties, and click the Advanced tab.
2. In the Print Dialog Presets section, set options and click OK.
The next time you open the Print dialog box, the values ​​will be set to the print preset values. These settings are also used when you print individual documents in a PDF Portfolio.
Note: To retain a print preset for a PDF, you must save the PDF after creating the print preset.
Print Dialog Presets
Page Scaling
Prepopulates the Page Scaling option in the Print dialog box with the option you choose:
Default
Uses the application default setting, which is Shrink To Printable Area.
None
Prevents automatic scaling to fit the printable area. This setting is useful for preserving the scale of page content in engineering documents, or for ensuring that documents print at a particular point size to be legal.”

Answer 2

Give them a layout with a picture?
EPS for the same vectors, TIFF for raster, for example.

Answer 3

You can do something like this:
Instead of pdf, give a link to a static html with a gif (a barcode of one fig b / w) and a script that, when onload opens 1-1 markup scale and all that remains is to poke "Print".
