    To do this you have to have the printer shared and know your computer name. You would then use the command at a dos prompt of:

    Netuse lpt3: \\computername\sharename

    You substitute the name of your computer and the sharename you have given the printer. If you get the command loaded successfully then you would copy the file to lpt3.

    Use this Attached Doc serial.doc Edit the file using the DOS editor to substitue your correct serial number and other info.

    You then would type at the command prompt: copy serial.doc lpt3 and hit the enter key.

      I can not imagine why is the counter so important on a cheap desktop printer? I do not want to be rude,just curious.

            Formatter costs 80% of the printer and you spend probably many hours to realize that failure is on formatter.

                  From service manual

                  WARNING! Do not install a replacement formatter PCA and DC controller PCA at the same time.The formatter PCA and the DC controller PCA store important product configuration information(NVRAM data) that is lost if both PCAs are replaced at the same time. When the product power isturned on, the DC controller restores the NVRAM data on the replacement formatter.
                  If it ain't broke, don't fix it
