Printers for virtual desktops and apps
Centralizing applications and desktops has many advantages. However, printing and print management are complex challenges. When printing with virtual apps and desktops, the following challenges are particularly important:
- Printer driver management and incompatibilities
- Large print data and slow printing
- Connection and preparation of printers
- Security of print data
Because of the many printer models on the market, there are thousands of printer drivers that are used on the PC's and must also be used on the virtual desktops. If the drivers do not match, errors occur, even if printer drivers are not compatible with the virtualization technologies.
In order to avoid problems, universal / virtual printer drivers should be used which work with all printer models and support as many functions as possible, e.g. Stapling, punching, or printing multiple pages per sheet. This allows virtual desktops and application servers to function free of printer drivers.
It is even better if the virtual printer driver can also be used on the workstations and printer drivers can only be held centrally in one place - on a central print server. A central print server also has the positive effect that remote desktop servers are freed from the workload of printing. This allows up to 20% more users per server to be supported.
Large print data and slow printing
Print data is easily ten times larger than the file to be printed, often 100 MB or more. This data must be transferred from the virtual desktop to the printers. Large print data can adversely affect the speed of printing as well as the application performance, thereby reducing user acceptance for virtual desktops.
Print data compression and caching ensure a reduction in the data to be transferred. It is important that these functions can also be used in conjunction with a print server, from the creation of the printout to the location of the printer. In addition, the compression should take effect when using the virtual protocols (RDP, HDX, PCoIP) as well as for network printing (TCP / IP).
For the speed of printing, the streaming of the print data is important. This means that the first page is transferred and printed out while the pages are still being printed on the server. This results in a much faster start of the printout. This prevents users from pressing the print button again and waiting for unnecessary print jobs.
In order to prevent a negative effect of the print data on the application performance, connection-oriented bandwidth control is the medium of choice. This ensures that printing does not interfere with other processes, no matter how many users print at the same time.
Providing the printer in the right place
BD users should have the local and network printers they need at the location they are working on, even if they change devices and locations.
Print management should provide flexible options, take local printers into account, and designate standard printers. An enormous challenge is the connection of network printers in masked networks - which can be used almost everywhere - for example when a print task itself is making use of secure gateways. Here, a software client or a printing device can make a secure connection to the central printing system in an external site.
The print solution should allow printers to be provided automatically and flexibly, based on various criteria, such as printer or username, and be especially dependent on the IP address range.
Virtual desktop users are also increasingly working on tablets, especially iPads. Here an app makes it possible to use not only network printers, but also local printers in the to facilitate the task.
Security of print data
Print files contain just as sensitive data as the original documents and should therefore be transmitted encrypted - from the data center to the printer locations. Therefore, make sure that your print solution provides encryption of the print data. A special tip: When printing in the DMZ, your print solution should only open ports in the direction of DMZ and not store any data in the DMZ.
