D is Duplex which mean it has the duplexer installed when manufactured. This could be added on older machines.  The new one is a problem as it requires a different approach.

T Mean it had additional tray supplied when sold, Again this can be added later

N mean it was supplied with a network card.

With the newer one that use X can not find the price list that explained all options.  But the ones I purchased did have network card, second tray and had Duplex working (so it a DTN).  The problem is upgrading these if you want duplex as the unit is built in already but not operational N or TN.  The A is USB Only but has duplex.

Never give up never give in.

There are no short cuts to anything worth doing   

Printer Models:
No extension  → Base model.
DN → Duplexer + Networkcard + extra memory.
DNM → DN + harddisk (Mopier).
DTN → DN + extra Tray.
DTNLS → Same as DTN but at reduced speed. Low budget model.
GN → Harddisk + Networkcard (Special edition of CLJ 9500)
HCI → High Capacity Input (1500 Sheets or bigger)
HDN → Harddisk + DN and usually extra tray & extra memory.
HNS → High capacity (typically 2000 or more sheets) + networkcard + stacker.
L → Low budget model. Limited expansion posibilities. Low speed, low memory & usually only one tray (manual). Typically host-based also.
LN →  Same as the L-model + Networkcard.
M → Mac compatible model !
MFP → Multi function printer (Digital copier/sender).
N → Networkcard (Might be embedded!).
NW → Networkcard + Wireless and/or Bluetooth.
TN → Extra Tray + Networkcard.
Si → Base model (LJ 5Si only).
SiMX  → Harddisk + extra memory + networkcard.
SiNX  → Networkcard + extra memory.
PH+ → Extra trays Paper Handling Plus (6 in total on the CLJ 4700 PH+)
X → Duplexer + Networkcard + extra tray.
NF → Networkcard + fax.
FXI → Networkcard + fax + card reader.

There are probably more extensions out there but those are the ones I know...

 

>> Some older/obscure ones: Cse, Cxi (or just x, i).

I believe that these would traditionally be DeskJet models.

C represents "Color", and the se, xi, x or i represents either the software bundle or the reseller.

For example, Staples used to sell the DeskJet 722Cse, whereas OfficeMax or Office Depot was selling the 722Cxi.

Same printer, different vendor, and possibly slightly different software bundle inside.

Cse and Cxi were inkjets, I believe.

SI was for series 3 and 4 Laser.  It was the Canon epn engine. The series III (3) was the first printer to use PCL5. It was 600dpi when other were only 300dpi.  The 4 had the SI, M and the unmaked 4. Like the II (2) the 3 also had a D model.
