One-line answer: The default invoice format decides
whether every invoice prints as an A4 page, an A5 page or a thermal
receipt (Customized). Set it once in Settings and all editions
(Restaurant, Retail, Retail 2nd Edition, Salon, Laundry, Weigh Scale and
ERP) will use it for POS Invoice and Sales Invoice printing.
Before you start
- Log in as admin (default user
admin). - Your printer must already be installed in Windows and selected in
Admin → Print Settings. - Decide the format: A4 for full-page invoices with logo and bank
details, A5 for half-page, Customized for 80 mm / 58 mm thermal
receipts.
Steps
- Open Admin → Settings. The SETTINGS screen opens on
the General1 tab. - Click the POS Settings tab. You see the POS options
such as POS Inv Form Option, POS Print
and Invoice Print Option. - Under Invoice Print Option choose A4
Print, A5 Print or
Customized.
- Click Apply. A confirmation message appears.
- Open Admin → Print Settings and check
Format and POS Inv Print Option match
your choice. Here you can also set Header Height,
Footer Height, Footer Note,
Stamp and Signature for A4 and A5.

- Click Apply on the Print Settings screen.
- Restart Vatrix so the new format loads on the invoice screen.
Check it worked
Make a test invoice in Transaction → POS Invoice and
click PRINT PREVIEW. The preview should open in the
format you selected. 
Common problems
- Invoice still prints as a receipt → Settings were
changed but Vatrix was not restarted. Close and open the software
again. - A4 prints without logo or address → Upload the logo
in Admin → Company Info and tick Company Name
in header in Print Settings. - Wrong printer used → Set the correct printer in
Admin → Print Settings and click Apply.

FAQ
Can I use A4 for Sales Invoice and thermal for POS
Invoice? Yes. Sales Invoice (ERP) uses the A4/A5 layout while
POS Invoice follows the POS Inv Print Option in Print Settings.
Does the format change old invoices? No. Old
invoices are reprinted in the new format only when you open and print
them again.
Can each location have its own format? Yes. In
Master → Location Master there is an Invoice
Print Format option per location.
