Type:        Software for Printserver Products
Target:      printserver ONE (HW 4.x)

md5sum: 	 be201156297ee02aad1c7bf3f82fa369
SHA-256:	 22eb5c2ab31ea4504ed9b3e402a80374baedc09bbbf7a52d79e81b3b2ca62d8f

Checksum Info:
The checksum allows to check whether the update file is the file provided by SEH before installation. 

A check can simply be done with e.g. the „shasum“ under macOS/Linux, „sha256sum“ under Linux 
or under Windows with the „ certutil“ tool, or in Powershell with the "Get-FileHash“ tool. 
The comparison can then be done manually (the hash values differ dramatically with a slight change) 
or with the -c option of the checksum commands in one step (see the following example for macOS/Linux):

Example macOS/Linux:
shasum -a 256 [FILENAME]
➔ echo '12dcb35076b40671d85262c265e80b8905e7839417da4119368fe5390faf36ed *d-sys-ps-10.4.40.bin' | shasum -c
d-sys-ps-10.4.40.bin: OK

Example Windows:
Windows command prompt:
CertUtil -hashfile [FILENAME] SHA256
C:>certutil -hashfile d-sys-ps-10.4.40.bin SHA256
SHA256 hash of d-sys-ps-10.4.40.bin:
12dcb35076b40671d85262c265e80b8905e7839417da4119368fe5390faf36ed
CertUtil: -hashfile command completed successfully.

- Contains important fixes and improvements
           
2) Fixes/Improvements:
----------------------
- [FIXED] printserver ONE: Printronix thermal printer products could encounter garbled printout.
  These thermal printers are not prepared to handle USB status requests while printing.  
  As a countermeasure our USB stack simply suppresses our periodical status requests.
- [FIXED] Under rar conditions the device could flood a network with DHCP DISCOVER packets.
  As a countermeasure the device is now limited to only send a DHCP message every 500ms.
