I've got an EPSON TM-T20 thermal receipt printer plugged to my Windows 7 machine. The printer has a serial port connection but my PC.
Hi, we have just switched to a web based Point of Sale system and the receipts print out very slowly in Chrome. At first they printed slow from any web browser.
Thermal Receipt Printer
Hello,I am trying to install the Epson TM T88IV receipt printer on an Ubuntu Server. I have managed to install it via cups, but it is printing very slowly. This printer will print receipts in under 1 sec on windows machines.
Steps so far:1. Plugged printer into serial port on back of server.2. Verified port by running 'dmseg grep tty'. In my case the printer was at '/dev/ttyS0'.3. Made this port writable 'chmod 0777 /dev/ttyS0'.4. Checked the baud rate of the port 'stty /dev/ttyS0'.
It printed a single line at good speed.7. Fired up cups (localhost:631)8. Added the printer via the cups web interface.
When prompted for the ppd, I used the thermal rastermount ppd downloaded from the Epson website.9. Entered maintenance section of the cups website and asked the printer to print a test page, which it did, but it took 60 seconds.So, the speed is far too slow for a work environment. I have messed around with the 'printer default settings' in cups, but to no avail. I think I am missing something in the cups config. With some searches, I think it may have something to do with spooling, but I am not sure how to change this.

Any help appreciated.Thank you.
Was it 0, 5 or 500? You see, you can't really 'go back' in this case. Sha hash crack youtube.

Question
How can I improve the printing speed?
How can I improve the printing speed?
Answer
There are a few factors that slow down the printing speed. Check the following.
1. Serial communication
1-1. If you use serial communication, check the baud rate.
1-2. Run the Self test of the printer to check the configured baud rate.
1-3. If the baud rate is low, change the Dip S/W settings to increase the speed.
1-4. When you change the Dip S/W Setting of the printer, the Baud rate of the application software and Windows driver should be set to the same value
as that of the printer. -> The printing data will be corrupted if the baud rates do not match.
1-5. If the printing speed is slow after increasing the baud rate, check the following.
2. Software
2-1. The printer has built-in fonts.
2-2. Application software can send commands to the printer to print with the built-in fonts.
2-3. Using the Windows fonts instead of built-in fonts makes the printing slow as the image of the font has to be transferred for printing.
2-4. If you cannot check the settings in the application software, contact the software company (POS program developers) to check the abovementioned
items.
3. Initially the printing speed was fast, but it is getting slower
3-1. Sometimes the printing speed becomes slower over time although the printing speed at initial setting was fast.
3-2. Check the application software in this case.
3-3. The printer prints out what it receives from the PC or POS system, so printer itself cannot become slower over time
3-4. The following factors may slow down the printing speed 1) Changes in settings 2) Larger data size 3) Changes in printing method.
3-4-1. Check the settings to see whether any of the settings have been changed.
3-4-2. Check the application software to see whether the printing method has been changed.
3-4-3. The size of data (DB) was not big at initial setting stage of the software and the search speed was fast, but the search speed becomes slower
as the data size grows. In this case, the printer is not the cause and you should check with the software company as it takes more time for the
PC to process the data.
* The difference between printing using built-in fonts and image printing is more than double.
