dymosoftware / drivers Goto Github PK

When trying to use the driver for LabelWriter 550 Turbo (lw550t.ppd) I kept getting an error saying "raster2dymolw_v2 file not found". A simple fix for this is to open up the .ppd file and change "raster2dymolw_v2" to "raster2dymolw". This is what worked for me anyway.

The uploaded LW4xx Linux.zip is actually a different version of LW5xx. It doesn't contain any LW4xx PPDs and is almost identical to the LW5xx zip:

$ wget https://github.com/dymosoftware/Drivers/raw/main/LW5xx%20Linux%201.4.3/LW5xx%20Linux%201.4.3.zip https://github.com/dymosoftware/Drivers/raw/main/LW4xx%20Linux/LW4xx%20Linux.zip
$ unzip -d LW4xx "LW4xx Linux.zip"
$ unzip -d LW5xx "LW5xx Linux 1.4.3.zip"
$ diff --recursive --ignore-space-change --brief LW4xx/Linux "LW5xx/LW5xx Linux 1.4.3"
Only in LW4xx/Linux: .DS_Store
Files LW4xx/Linux/Makefile.in and LW5xx/LW5xx Linux 1.4.3/Makefile.in differ
Only in LW4xx/Linux/src: .DS_Store
Only in LW4xx/Linux/src/boost/preprocessor: debug

When following the instructions in INSTALL, it says to do ./configure and then make. When doing make, it eventually tries to access ppd/Linux which is not included in the repository.

Summary

The print density command line optional argument does not appear to work causing the printer to crash only on the LW 550 Turbo and not the LW 450 Turbo.

Removing the flag allows 550 Turbo printer to work normally. Exact command with density flag can be used on 450 Turbo.

Operating System: Raspbian 11 Bullseye
Using command: lpr

Debugging Measures Performed:

Test 1:
Remove print density flag from lpr command
Change LabelWriterDriverV2.cpp's normal flag command character to:
case pdNormal:
cmdBuffer[1] = 'e'; -> 'g' (the one for pdDark)
break;
Recompile and install drivers, print test page from cups on localhost:631
Result: label does not print

Test 2:
Remove print density flag from lpr command
Change LabelWriterDriverV2.cpp's normal flag command character to:
case pdNormal:
cmdBuffer[1] = 'e'; -> 'c' (the one for pdLight)
break;
Recompile and install drivers, print test page from cups on localhost:631
Result: label does not print

Conclusion

It would appear the driver is cannot work with the printer's embedded firmware on the LW 550 Turbo to change the print density to other than the default value.

Hello! Trying to get a LabelWriter 550 set up on my old pi 3B+, I grabbed the lw550.ppd and modified it to only use "raster2dymolw" instead of v2 since v2 didn't exist on the system.

I did try running the makefile installation process but it died at:

Makefile:472: .deps/raster2dymolw.Po: No such file or directory

Any assistance is appreciated! I have it set up in CUPS and I can see from the web UI that it is online and idle, I can send print jobs from network clients, it even shows them processing to the printer and completing, but the printer never does anything.

Hi there,

Trying to compile drivers on my RPI3 on updated version of rasbian (bullseye)

In Makefile, I had to change:

# Line 221
ACLOCAL = aclocal-1.16

# Line 226
AUTMAKE = automake-1.16

Regards,
