I have a client who absolutely needs to print their work orders using a dot matrix printer. I am having a strange issue where the printing shifts downwards by a very small amount after every page printed.
The first page comes out fine, by the 10th page the printing has shifted down by approximately 5mm.
These printers are connected locally via USB to their PC's. They log onto an ERP system hosted as a remoteapp.
Printing locally is fine, testing the ERP system locally the print job never shifts. However by logging on through remoteapp the print job shifts.
Previously we were using the EasyPrint driver but I have now installed the appropriate driver onto the server itself. This has made no change.
We suspect that the problem is in the paper size used. They use a non-standard paper size called A4 fanfold. This paper is approximately 0.6mm shorter than a regular A4 piece of paper.
We set this paper size on the local machine's printer driver properties and we can see it under the "available paper" section on the first tab.
However once RDP'ed onto the RDSH server the redirected printer reports that it has A4 paper in the available paper section. We do not know if this is simply the default thing it reports. You cannot change the paper selection in the last tab of printer properties as it is all greyed out like you can on the local print driver.
One thing we did discover with the epson print driver was that going into printer preferences we can specify the paper size used in the tractor feed. However doing this does not change the reported paper available nor does it fix the issue.
I have read on one kb article that this problem maybe due to the form ID's used for paper size's not matching between the client and server. However installing the printer driver onto the server should have resolved this according to the kb article. Which it didn't.
One thing that makes me suspect we are having a paper size issue in combination with RDP is that we are having the same exact issue with an Oki dot matrix printer as well. With the Oki driver though it does not even give us A4 fanfold as a choice in the printer preferences unlike the epson.
