The customer has never used Purchase Orders in NetSuite. They created a Purchase Order forms and the logo size on the printed version of the PO is much too small. The customer need help identifying why it's small. They did not select a logo on the entry form, as because they want the logo to pull from the subsidiary record.
Check the following:
Check the Logo Scaling Factor to see the scaling percentage of Logo on Basic PDF, Setup > Company > Printing & Fax > Logo Scaling Factor and adjust when needed.
Check the size of the logo uploaded on the Subsidiary record, if the uploaded image has a low resolution, it could be the reason why the logo is showing much too small on printed forms
