Forgotten printer parameter

This week I visited a new client of WaiterOne: Svenska Baren in Puerto Rico, G.C. Armed with my MacBook Pro and my iPad mini, I would tackle a ticket printer layout bug. As I don’t have an Epson TM-T20II here to test, I just made an appointment with the owner of the place to test it onsite. Connect my hardware to his network, …, ready, set, … debug :

As you see, the ticket width doesn’t seem to be used completely. But then again, the total of the ticket seems to be well aligned, also the text printed in the header and the footer seems to be exactly in the middle. Strange no? As my personal printer on my work place, seems to be working perfect. Small detail, it is not an Epson TM-T20II, but a Epson TM-T88V with wifi interface.

It didn’t took me long to see that the printing was just that little bit smaller then my own test prints. So if it prints smaller, then it probably also prints more columns?

Downloaded the Epson TM-T20II and the Epson TM-T88V specs and indeed, the first printer prints in Font A 48 characters, in Font B 64 characters on 1 line, the latter printer does 42 characters and 56 characters respectively in Font A and Font B. Eureka!!

As soon as I changed in WaiterOne the characters to 64 on the bill printer (data -> printers -> bill -> ticket : characters) all seems to be working as it should. Everybody happy, table foosball puppet included :

Rongta printers

WaiterOne is already working with a lot of POS printers. We have printers from Epson, Citizen, Star, Bixolon, … One of our Australian support technicians, Ian, suggested a new printer brand. Especially as the common models used here in Europe and the US are crazy expensive in Australia. Don’t know why but actually all hardware seems to be quite expensive down under. On the other hand if you should go to Canada once, can I assume that this is up above then, go tech shopping, as prices there seems to be incredible cheap at this moment.
Ian suggested to check out the printers from Xiamen Rongta Tech. Some of the models seems to have all the specs WaiterOne needs at an exceptional low price. And if I say low, I really mean low. Imagine that you can buy a POS printer with a wifi interface for a third of the price of an Epson TM-T88V. In case you are looking for a cheap POS printer, have a look at Rongta. We will test one very soon now, if you can get your hands on one, let me know how it performs!
