Quite interesting that 2 customers asked the same question today.
Another dealer told me last night that we"assume" that everyone knows the answers... So PLEASE help us to help you. Ask, ask, ask! 4POS can MOST LIKELY do what you have wondered about....!
To print your logo on the A4-invoices, simply copy your logo to the 4POS folder with a name called 4POSLogo.bmp Obviously you need to play around with the sizing etc.....
To print your logo on your receipts, simply copy your logo to the 4POS folder with a name called 4POSLogoslip.bmp Obviously you need to play around with the sizing etc.....
Also, on your receipts, ensure you have the proper driver loaded & your configuration in 4POS :
On 4POSScan - Ctrl-C
On 4POSTouch - Option Menu - Ctrl-C
Then : Option 3 "Print Graphics" is ticked & "Print Logo" is ticked.
