Question about Samsung BIXOLON® STP-103 Printer

1 Answer

Samsung STP-103 Thermal Printer will not print lines correctly

I have an "ALGE Timy" timing computer connected to a Samsung STP-103 printer. Both units use ASCII 1 start, no parity, 8 data,1 stopbit.
Yet when printing each line of information (which is set to 21 characters) the print carries on without starting on a new line (like it has not seen the stop bit, tnnew line). I have tried changing the dip switch on the back of the 103 which give two options for how many characters per line but neither works correctly only the character spacing changes.
Your suggestions.

Wow, serial communications still in use. Naturally, both units have to use the exact same protocol N81 for instance, so make certain the sending unit is set to the same, then check the cable to verify that the appropriate pins are connected and or crossed. I believe your symptoms can be caused by using hardware handshake and having pins 6,8,20 (20 only if a 25pin connector) shorted on the printer end. If possible, you can try switching both devices to software handshake.

I think this printer has a cash drawer open version and a standard non-cash drawer version. Make sure you have the right model of the unit. If the setting on the driver is not "holding" it is likely a user access setting issue (UAC). make sure you have admin privileges. Depending on what type of windows you have it'll be different.

Zebra 105Se missing line

Try cleaning the thermal printhead. Zebra makes thermal printhead cleaners or you can use a qtip and some isopropyl alcohol.

Make sure the printer is turned off before doing this.
