Robocopy Example

The following robocopy command will transfer C:\Data to E:\Data with the following options:

robocopy C:\Data E:\Data /e /dcopy:t /sec /r:0 /np /xo /tee /log:c:\robocopy.log /mt:16
  • /e — copy subdirectories, including empty ones
  • /dcopy:t — copy directory timestamps
  • /sec — copy files with security (equivalent to /COPY:DATS (Data, Attributes, Timestamps, Security))
  • /r:0 — number of retries on failed copies: 0
  • /np — no progress (don’t display percentage copied in the log)
  • /xo — exclude older files (i.e. don’t overwrite newer files already in the destination)
  • /tee — output to console window, as well as the log file (skip if using /mt)
  • /log — output status to LOG file (overwrite existing log)
  • /mt — Do multi-threaded copies with n threads (default 8)

Dymo LabelWriter 400 printer error

I purchased an older, used Dymo LabelWriter 400 from eBay, installed it on my Windows 7 x64 desktop and printed a test page only to have it throw a very generic message: “Printer error”.

Go to your Dymo LabelWriter 400 printer properties, click the Ports tab and uncheck the “Enable bidirectional support” checkbox. While that got it working, I was a little annoyed at having to disable two-way communication between the printer and my computer. I dug a little deeper and found an old Dymo support article that mentions a firmware update to fix a similar issue. The link to the firmware update is broken, but I was able to find it at another Dymo site. After running the updater and power cycling the printer, I re-enabled bidirectional support and successfully printed several labels.
