I have a ​Samsung ML-1750 printer with a ​TL-Link TL-PS110P Single Parallel Port Fast Ethernet Print Server functioning as my BW laser printer for a long time.

The Linux drivers still ​work like a sharm, yet on Windows on every new release it becomes more and more a struggle to keep the printer running. In order to keep it running under Windows 10 x64 it is a challenge.

FreeBSD CUPS Server within jail

My printer is connected via usb and exposed as ulpt(4) which is exposed via devfs.rules(5) to the jail.

Note: usb descriptors are be named or numbers differently per instance, printer or configuration. Sample of mine setup:

host# dmesg

ugen0.6: <Samsung Electronics Co., Ltd. Samsung ML-1750 Series> at usbus0
ulpt0 on uhub5
ulpt0: <Samsung Electronics Co., Ltd. Samsung ML-1750 Series, class 0/0, rev 2.00/1.00, addr 6> on usbus0
ulpt0: using bi-directional mode

Windows 10 (x64) instalation

Background

• The PCL6 version of the printer is 3.15 (03-03-2003), I have tried printing with the Samsung generic PCL6 driver, yet this yield "PCL6 ERRROR", so imcompatible PCL6 commands are issued
• The PCL5e 1.63 (03-06-2003) yet I cannot not find a generic Windows default driver for it.
• The EPSON/IBM 1.02 (01-23-2003) has also no compatible driver.
• The SPL 1.16 (12-30-2002) the Samsung Printing Language is luckaly still supported by the generic driver.

Instalation

I have done the following steps:

• Install the "Universal Print Driver ver V2.50.06.00:03, Win 2000/XP/2003/2008/Vista/Win 7/Win 8(32/64bit) (MULTI LANGUAGE)" from the ​support page Altough it does not list "Win 10" it will still install fine.
• Install and configure the TL-PS110P acording to its ​manual

Printing now works yet it only prints one job and this job never finishes (sticks in the queue). Searching for the answer, Brooksnet ​provided me with a usefull hint about enabling the LPR Byte Counting. I guess this is required for the TL-PS110P to handle my print requests properly:

Just to be sure I also checked the Samsung driver details page and set the protocol to SPL and selected the correct model:
