The following advice is based on guesses, although I have a reasonable amount of experience with resolving printer issues on Windows 7. If this is not the only thermal receipt printer you must use, perhaps purchasing a different printer, from a better-known manufacturer such as Epson, might be the solution. It will cost more initially, but you'll probably get better support.
The error message appears to be generated by the printer driver installation package rather than Windows, so I don't know what problem it is referring to.
If you have never installed this printer or other printers from the same manufacturer, perhaps attempting the installation from a "clean boot" configuration will work.
- Click Start, type msconfig in the Search box, and press Enter
- On the "General" tab, select "Selective startup"
- Clear the box next to "Load startup items"
- Select the "Services" tab
- Check the box at the bottom left to "Hide all Microsoft services"
- Click "Disable all"
- Click "OK"
- Click "Restart"
Attempt to install the printer following the manufacturer's instructions.
Whether you succeed of not, when you are done, open msconfig again, select "Normal startup" on the "General" tab, click OK, and then restart.
If you HAVE previously installed, or partially installed, this printer or other thermal receipt printers, one possible solution is to clean out your printing system. There are several methods for doing this. The following is the basic and simplest method.
A. Clean out any stuck print jobs --
- Open an Elevated Command Prompt: Click Start, type Command Prompt in the Search window, right-click the link for Command Prompt, and select "Run as administrator." Respond as needed to the UAC prompt
- Type the following in the black Command Prompt window and press Enter after each line
net stop spooler
del /Q "%windir%\system32\spool\PRINTERS\*.*"
net start spooler
exit
B. Clean out the corrupt printer driver
- Uninstall printer-related software, if any, from Control Panel > Programs and Features
- Open an Elevated Command Prompt (see above)
- Type the following in the black Command Prompt window and press Enter
printui /s /t2
exit
Be sure to remove the driver AND the package.
C. Reinstall printer using freshly-downloaded software package.
There is a more involved method that essentially restores the Windows printing subsystem to the state it was in when Windows was freshly installed, but I doubt this would be necessary in the situation you've described or effective in solving your problem.
