Test Print Page
Dibe Naro
I set up a receipt under Accounts & Settings/Receipts. under the Logotype, there is a statement that says "Please test print your receipt to confirm actual print quality.", but, I find no "test print" button, nor any instruction as to how one can print a 'test receipt'.
From the Square Terminal, press Transactions at the bottom of the screen. Select a transaction and press the ">" button to the far right. Press the "New Receipt" button and it will print you a new receipt with the current custom settings.
I am having problem with printing invoice, when ever i am printing invoice some standard page (SAP Test print page) is also printing , this issue is onley in quality and production, in development it is working fine.
The printed contents in the printer test print(self-printing) can be confirmed the firmware version(*), memory switch settings, and interface settings. (*)The firmware version is printed in the title section of the printer information (1st page).
After binding to the printer (and our collection will consist of only one printer, because DeviceIDs must be unique) we call the PrintTestPage method, capturing the return value in a variable named errReturn. If errReturn is 0 that means the test page printed successfully; if errReturn is anything but 0 then something went wrong and the test page could not be printed. Either way we echo the appropriate message to the screen.
Like we said, pretty easy. What makes this especially nice is : 1) because this is WMI, we can print test pages from remote machines just as easily as we can from the local machine; and, 2) the return value will tell us whether or not the print test succeeded. No need to walk all the way to the printer only to find out that, for some reason, the print test failed.
Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
