I can not find anything!
I know that I need to change the printer.
thanks anyway
I found this guide:
the problem is that I can not send the command through XCT
has anyone tried or can recommend me?
thanks
I also found this document, clearer
I send the command, but the printer does not change the settings!
So you have tried
XCT 27,33,48
Iāve tried it!
I also tried with XCT 27, 33, 176 and I print with underline
but the size does not change
If it prints underline it shows you can send the correct command. Did you tried 16 or 177 as well?
16 I tried but nothing! 177 print underline but still smaller
I contacted epson and told me that the command 27,33, 32 and right!
is there a way to send the command to the printer, maybe from the terminal?
Spanky you can send command to printer because it understands underline but for a reason it doesnāt change size. Iām thinking if using <Lxx> resets size or not. Your printer does not support GS ! command but it may reset font size. Can you try without using a tag before line?
I tried just putting
<XCT> 27, 33, 176
hello
but nothing!
the TM U220 does not support <L00> or <C00>
but only double-height and double-width.
What does it say GS!?
Hi i want to know whether your printer problem resolved or not beacuse i was about to buy epson tm u 220
any suggestion whether i should buy or not
is thermal better than dot matrix
speed wise and setup wise?
Here are 5 reasons why a thermal receipt printer is superior to a dot matrix receipt printer.
- Speed
Thermal printers print at an incredible rate when compared to dot matrix printers. The average dot matrix printer will print around 3 lines per second. Thermal printers average in excess of 20 lines per second.
- Print Quality
Thermal receipt printers have a much better image and print quality than dot matrix receipt printers. The name ādot matrixā helps explain the major difference between the two very different technologies.
The dot matrix or impact printer creates characters by impacting a ribbon with up to 8 small wires that are aligned vertically in a dot head. As the dot head travels horizontally across the ribbon/paper these dots impact like small hammers making the impression on the ribbon and then the paper. Look closely at a receipt printed by a dot matrix printer and you will see these very small dots that make up the characters.
These dots simply do not have the quality of image that a thermal receipt printer does.
- Logo Images
Dot matrix receipt printers go not have the ability to print a quality logo image on the receipt. Thermal receipt printers not only have this ability the image does have some very fine detail and is easy to download to the printer to be stored in the printerās RAM.
- Reliability
MTBF stands for Mean Time Between Failure. This is the standard for measuring the average time between failure for any device. In the case of printers it is either the average number of lines printed before a failure occurs or the average feet of paper that can be printed before a failure occurs.
In either case, the thermal receipt printers win across the board.
There are some thermal receipt printers that are better than others, but dot matrix printers simply do not have the staying power of a thermal printer.
This is due to fewer moving parts on a thermal printer and the fact that dot heads break due to the dot pins snagging on ribbons or are damaged when coins are dropped into the printer mechanism.
Thermal receipt printers do not have these extra moving parts as the paper is pulled across a stationary heat mechanism that heats the thermal paper to make the characters and images.
- Cost of Ownership
This goes beyond simply the cost of supplies. This analysis should also include downtime and the cost of repairs.
Thermal paper does cost more than dot matrix paper. However, the added cost of ribbons for the dot matrix printer sends the cost of ownership for supplies higher for the dot matrix receipt printer.
When you add in the cost of repairs and the more frequent repairs for the dot matrix receipt printers the cost of ownership clearly swings in favor of thermal receipt printers.
The only good thing that I know of dot matrix printers is that they can be used in hot areas and the printouts are not affected by heat.
I could not!
but surely there will be a way or a command that allows you to do so.
Thatās the concept but I would not go with dot matrix and simply position a thermal away from heat but still close enough for the chef.
why is it hard to configure and setupā¦not fully supported by sambapos or wht?
Hi Morshed,
You are right, thermal printers are good.
However in a lot of countries matrix printers are mandatory for bills.
As you see on this photo, only matrix (mechanic) printer can print a 3-papers roll:
- 2 for the customer (red and white)
- 1 rolled inside the printer (yellow) and has to be kept 3 years for tax control purpouse.

We are using GS! command to increase font size and as shown on the documentation that posted on top of this thread TMU 220 model does not support this command. Iāve requested a printer from our hardware vendor to test ESC! command. They donāt have a TMU220 for testing but Iāll implement support for that command. If TM U220 supports ESC! as advertised we may solve font size issue.
